-# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
-# $ac_aux_dir to '$srcdir/foo'.  In other projects, it is set to
-# '$srcdir', '$srcdir/..', or '$srcdir/../..'.
-#
-# Of course, Automake must honor this variable whenever it calls a
-# tool from the auxiliary directory.  The problem is that $srcdir (and
-# therefore $ac_aux_dir as well) can be either absolute or relative,
-# depending on how configure is run.  This is pretty annoying, since
-# it makes $ac_aux_dir quite unusable in subdirectories: in the top
-# source directory, any form will work fine, but in subdirectories a
-# relative path needs to be adjusted first.
-#
-# $ac_aux_dir/missing
-#    fails when called from a subdirectory if $ac_aux_dir is relative
-# $top_srcdir/$ac_aux_dir/missing
-#    fails if $ac_aux_dir is absolute,
-#    fails when called from a subdirectory in a VPATH build with
-#          a relative $ac_aux_dir
-#
-# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
-# are both prefixed by $srcdir.  In an in-source build this is usually
-# harmless because $srcdir is '.', but things will broke when you
-# start a VPATH build or use an absolute $srcdir.
-#
-# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
-# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
-#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
-# and then we would define $MISSING as
-#   MISSING="\${SHELL} $am_aux_dir/missing"
-# This will work as long as MISSING is not called from configure, because
-# unfortunately $(top_srcdir) has no meaning in configure.
-# However there are other variables, like CC, which are often used in
-# configure, and could therefore not use this "fixed" $ac_aux_dir.
-#
-# Another solution, used here, is to always expand $ac_aux_dir to an
-# absolute PATH.  The drawback is that using absolute paths prevent a
-# configured tree to be moved without reconfiguration.

-\`configure' configures dash 0.5.11.4 to adapt to many kinds of systems.
-
-Usage: $0 [OPTION]... [VAR=VALUE]...
-
-To assign environment variables (e.g., CC, CFLAGS...), specify them as
-VAR=VALUE.  See below for descriptions of some of the useful variables.
-
-Defaults for the options are specified in brackets.
-
-Configuration:
-  -h, --help              display this help and exit
-      --help=short        display options specific to this package
-      --help=recursive    display the short help of all the included packages
-  -V, --version           display version information and exit
-  -q, --quiet, --silent   do not print \`checking ...' messages
-      --cache-file=FILE   cache test results in FILE [disabled]
-  -C, --config-cache      alias for \`--cache-file=config.cache'
-  -n, --no-create         do not create output files
-      --srcdir=DIR        find the sources in DIR [configure dir or \`..']
-
-Installation directories:
-  --prefix=PREFIX         install architecture-independent files in PREFIX
-                          [$ac_default_prefix]
-  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
-                          [PREFIX]
-
-By default, \`make install' will install all the files in
-\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
-an installation prefix other than \`$ac_default_prefix' using \`--prefix',
-for instance \`--prefix=\$HOME'.
-
-For better control, use the options below.
-
-Fine tuning of the installation directories:
-  --bindir=DIR            user executables [EPREFIX/bin]
-  --sbindir=DIR           system admin executables [EPREFIX/sbin]

-
-Some influential environment variables:
-  CC          C compiler command
-  CFLAGS      C compiler flags
-  LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
-              nonstandard directory <lib dir>
-  LIBS        libraries to pass to the linker, e.g. -l<library>
-  CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
-              you have headers in a nonstandard directory <include dir>
-
-Use these variables to override the choices made by `configure' or to help
-it to find libraries and programs with nonstandard names/locations.
-
-Report bugs to the package provider.

-
-NOTE -- This is the original TOUR paper distributed with ash and
-does not represent the current state of the shell.  It is provided anyway
-since it provides helpful information for how the shell is structured,
-but be warned that things have changed -- the current shell is
-still under development.
-
-================================================================
-
-                       A Tour through Ash
-
-               Copyright 1989 by Kenneth Almquist.
-
-
-DIRECTORIES:  The subdirectory bltin contains commands which can
-be compiled stand-alone.  The rest of the source is in the main
-ash directory.
-
-SOURCE CODE GENERATORS:  Files whose names begin with "mk" are
-programs that generate source code.  A complete list of these
-programs is:
-
-        program         intput files        generates
-        -------         ------------        ---------
-        mkbuiltins      builtins            builtins.h builtins.c
-        mkinit          *.c                 init.c
-        mknodes         nodetypes           nodes.h nodes.c
-        mksignames          -               signames.h signames.c
-        mksyntax            -               syntax.h syntax.c
-        mktokens            -               token.h
-        bltin/mkexpr    unary_op binary_op  operators.h operators.c
-
-There are undoubtedly too many of these.  Mkinit searches all the
-C source files for entries looking like:
-
-        INIT {
-              x = 1;    /* executed during initialization */
-        }
-
-        RESET {
-              x = 2;    /* executed when the shell does a longjmp
-                           back to the main command loop */
-        }
-
-It pulls this code out into routines which are when particular
-events occur.  The intent is to improve modularity by isolating
-the information about which modules need to be explicitly
-initialized/reset within the modules themselves.
-
-Mkinit recognizes several constructs for placing declarations in
-the init.c file.
-        INCLUDE "file.h"
-includes a file.  The storage class MKINIT makes a declaration
-available in the init.c file, for example:
-        MKINIT int funcnest;    /* depth of function calls */
-MKINIT alone on a line introduces a structure or union declara-
-tion:
-        MKINIT
-        struct redirtab {
-              short renamed[10];
-        };
-Preprocessor #define statements are copied to init.c without any
-special action to request this.
-
-INDENTATION:  The ash source is indented in multiples of six
-spaces.  The only study that I have heard of on the subject con-
-cluded that the optimal amount to indent is in the range of four
-to six spaces.  I use six spaces since it is not too big a jump
-from the widely used eight spaces.  If you really hate six space
-indentation, use the adjind (source included) program to change
-it to something else.
-
-EXCEPTIONS:  Code for dealing with exceptions appears in
-exceptions.c.  The C language doesn't include exception handling,
-so I implement it using setjmp and longjmp.  The global variable
-exception contains the type of exception.  EXERROR is raised by
-calling error.  EXINT is an interrupt.
-
-INTERRUPTS:  In an interactive shell, an interrupt will cause an
-EXINT exception to return to the main command loop.  (Exception:
-EXINT is not raised if the user traps interrupts using the trap
-command.)  The INTOFF and INTON macros (defined in exception.h)
-provide uninterruptable critical sections.  Between the execution
-of INTOFF and the execution of INTON, interrupt signals will be
-held for later delivery.  INTOFF and INTON can be nested.
-
-MEMALLOC.C:  Memalloc.c defines versions of malloc and realloc
-which call error when there is no memory left.  It also defines a
-stack oriented memory allocation scheme.  Allocating off a stack
-is probably more efficient than allocation using malloc, but the
-big advantage is that when an exception occurs all we have to do
-to free up the memory in use at the time of the exception is to
-restore the stack pointer.  The stack is implemented using a
-linked list of blocks.
-
-STPUTC:  If the stack were contiguous, it would be easy to store
-strings on the stack without knowing in advance how long the
-string was going to be:
-        p = stackptr;
-        *p++ = c;       /* repeated as many times as needed */
-        stackptr = p;
-The following three macros (defined in memalloc.h) perform these
-operations, but grow the stack if you run off the end:
-        STARTSTACKSTR(p);
-        STPUTC(c, p);   /* repeated as many times as needed */
-        grabstackstr(p);
-
-We now start a top-down look at the code:
-
-MAIN.C:  The main routine performs some initialization, executes
-the user's profile if necessary, and calls cmdloop.  Cmdloop is
-repeatedly parses and executes commands.
-
-OPTIONS.C:  This file contains the option processing code.  It is
-called from main to parse the shell arguments when the shell is
-invoked, and it also contains the set builtin.  The -i and -j op-
-tions (the latter turns on job control) require changes in signal
-handling.  The routines setjobctl (in jobs.c) and setinteractive
-(in trap.c) are called to handle changes to these options.
-
-PARSING:  The parser code is all in parser.c.  A recursive des-
-cent parser is used.  Syntax tables (generated by mksyntax) are
-used to classify characters during lexical analysis.  There are
-three tables:  one for normal use, one for use when inside single
-quotes, and one for use when inside double quotes.  The tables
-are machine dependent because they are indexed by character vari-
-ables and the range of a char varies from machine to machine.
-
-PARSE OUTPUT:  The output of the parser consists of a tree of
-nodes.  The various types of nodes are defined in the file node-
-types.
-
-Nodes of type NARG are used to represent both words and the con-
-tents of here documents.  An early version of ash kept the con-
-tents of here documents in temporary files, but keeping here do-
-cuments in memory typically results in significantly better per-
-formance.  It would have been nice to make it an option to use
-temporary files for here documents, for the benefit of small
-machines, but the code to keep track of when to delete the tem-
-porary files was complex and I never fixed all the bugs in it.
-(AT&T has been maintaining the Bourne shell for more than ten
-years, and to the best of my knowledge they still haven't gotten
-it to handle temporary files correctly in obscure cases.)
-
-The text field of a NARG structure points to the text of the
-word.  The text consists of ordinary characters and a number of
-special codes defined in parser.h.  The special codes are:
-
-        CTLVAR              Variable substitution
-        CTLENDVAR           End of variable substitution
-        CTLBACKQ            Command substitution
-        CTLESC              Escape next character
-
-A variable substitution contains the following elements:
-
-        CTLVAR type name '=' [ alternative-text CTLENDVAR ]
-
-The type field is a single character specifying the type of sub-
-stitution.  The possible types are:
-
-        VSNORMAL            $var
-        VSMINUS             ${var-text}
-        VSMINUS|VSNUL       ${var:-text}
-        VSPLUS              ${var+text}
-        VSPLUS|VSNUL        ${var:+text}
-        VSQUESTION          ${var?text}
-        VSQUESTION|VSNUL    ${var:?text}
-        VSASSIGN            ${var=text}
-        VSASSIGN|VSNUL      ${var=text}
-
-The name of the variable comes next, terminated by an equals
-sign.  If the type is not VSNORMAL, then the text field in the
-substitution follows, terminated by a CTLENDVAR byte.
-
-Commands in back quotes are parsed and stored in a linked list.
-The locations of these commands in the string are indicated by
-the CTLBACKQ character.
-
-The character CTLESC escapes the next character, so that in case
-any of the CTL characters mentioned above appear in the input,
-they can be passed through transparently.  CTLESC is also used to
-escape '*', '?', '[', and '!' characters which were quoted by the
-user and thus should not be used for file name generation.
-
-CTLESC characters have proved to be particularly tricky to get
-right.  In the case of here documents which are not subject to
-variable and command substitution, the parser doesn't insert any
-CTLESC characters to begin with (so the contents of the text
-field can be written without any processing).  Other here docu-
-ments, and words which are not subject to splitting and file name
-generation, have the CTLESC characters removed during the vari-
-able and command substitution phase.  Words which are subject
-splitting and file name generation have the CTLESC characters re-
-moved as part of the file name phase.
-
-EXECUTION:  Command execution is handled by the following files:
-        eval.c     The top level routines.
-        redir.c    Code to handle redirection of input and output.
-        jobs.c     Code to handle forking, waiting, and job control.
-        exec.c     Code to path searches and the actual exec sys call.
-        expand.c   Code to evaluate arguments.
-        var.c      Maintains the variable symbol table.  Called from expand.c.
-
-EVAL.C:  Evaltree recursively executes a parse tree.  The exit
-status is returned in the global variable exitstatus.  The alter-
-native entry evalbackcmd is called to evaluate commands in back
-quotes.  It saves the result in memory if the command is a buil-
-tin; otherwise it forks off a child to execute the command and
-connects the standard output of the child to a pipe.
-
-JOBS.C:  To create a process, you call makejob to return a job
-structure, and then call forkshell (passing the job structure as
-an argument) to create the process.  Waitforjob waits for a job
-to complete.  These routines take care of process groups if job
-control is defined.
-
-REDIR.C:  Ash allows file descriptors to be redirected and then
-restored without forking off a child process.  This is accom-
-plished by duplicating the original file descriptors.  The redir-
-tab structure records where the file descriptors have be dupli-
-cated to.
-
-EXEC.C:  The routine find_command locates a command, and enters
-the command in the hash table if it is not already there.  The
-third argument specifies whether it is to print an error message
-if the command is not found.  (When a pipeline is set up,
-find_command is called for all the commands in the pipeline be-
-fore any forking is done, so to get the commands into the hash
-table of the parent process.  But to make command hashing as
-transparent as possible, we silently ignore errors at that point
-and only print error messages if the command cannot be found
-later.)
-
-The routine shellexec is the interface to the exec system call.
-
-EXPAND.C:  Arguments are processed in three passes.  The first
-(performed by the routine argstr) performs variable and command
-substitution.  The second (ifsbreakup) performs word splitting
-and the third (expandmeta) performs file name generation.  If the
-"/u" directory is simulated, then when "/u/username" is replaced
-by the user's home directory, the flag "didudir" is set.  This
-tells the cd command that it should print out the directory name,
-just as it would if the "/u" directory were implemented using
-symbolic links.
-
-VAR.C:  Variables are stored in a hash table.  Probably we should
-switch to extensible hashing.  The variable name is stored in the
-same string as the value (using the format "name=value") so that
-no string copying is needed to create the environment of a com-
-mand.  Variables which the shell references internally are preal-
-located so that the shell can reference the values of these vari-
-ables without doing a lookup.
-
-When a program is run, the code in eval.c sticks any environment
-variables which precede the command (as in "PATH=xxx command") in
-the variable table as the simplest way to strip duplicates, and
-then calls "environment" to get the value of the environment.
-There are two consequences of this.  First, if an assignment to
-PATH precedes the command, the value of PATH before the assign-
-ment must be remembered and passed to shellexec.  Second, if the
-program turns out to be a shell procedure, the strings from the
-environment variables which preceded the command must be pulled
-out of the table and replaced with strings obtained from malloc,
-since the former will automatically be freed when the stack (see
-the entry on memalloc.c) is emptied.
-
-BUILTIN COMMANDS:  The procedures for handling these are scat-
-tered throughout the code, depending on which location appears
-most appropriate.  They can be recognized because their names al-
-ways end in "cmd".  The mapping from names to procedures is
-specified in the file builtins, which is processed by the mkbuil-
-tins command.
-
-A builtin command is invoked with argc and argv set up like a
-normal program.  A builtin command is allowed to overwrite its
-arguments.  Builtin routines can call nextopt to do option pars-
-ing.  This is kind of like getopt, but you don't pass argc and
-argv to it.  Builtin routines can also call error.  This routine
-normally terminates the shell (or returns to the main command
-loop if the shell is interactive), but when called from a builtin
-command it causes the builtin command to terminate with an exit
-status of 2.
-
-The directory bltins contains commands which can be compiled in-
-dependently but can also be built into the shell for efficiency
-reasons.  The makefile in this directory compiles these programs
-in the normal fashion (so that they can be run regardless of
-whether the invoker is ash), but also creates a library named
-bltinlib.a which can be linked with ash.  The header file bltin.h
-takes care of most of the differences between the ash and the
-stand-alone environment.  The user should call the main routine
-"main", and #define main to be the name of the routine to use
-when the program is linked into ash.  This #define should appear
-before bltin.h is included; bltin.h will #undef main if the pro-
-gram is to be compiled stand-alone.
-
-CD.C:  This file defines the cd and pwd builtins.  The pwd com-
-mand runs /bin/pwd the first time it is invoked (unless the user
-has already done a cd to an absolute pathname), but then
-remembers the current directory and updates it when the cd com-
-mand is run, so subsequent pwd commands run very fast.  The main
-complication in the cd command is in the docd command, which
-resolves symbolic links into actual names and informs the user
-where the user ended up if he crossed a symbolic link.
-
-SIGNALS:  Trap.c implements the trap command.  The routine set-
-signal figures out what action should be taken when a signal is
-received and invokes the signal system call to set the signal ac-
-tion appropriately.  When a signal that a user has set a trap for
-is caught, the routine "onsig" sets a flag.  The routine dotrap
-is called at appropriate points to actually handle the signal.
-When an interrupt is caught and no trap has been set for that
-signal, the routine "onint" in error.c is called.
-
-OUTPUT:  Ash uses it's own output routines.  There are three out-
-put structures allocated.  "Output" represents the standard out-
-put, "errout" the standard error, and "memout" contains output
-which is to be stored in memory.  This last is used when a buil-
-tin command appears in backquotes, to allow its output to be col-
-lected without doing any I/O through the UNIX operating system.
-The variables out1 and out2 normally point to output and errout,
-respectively, but they are set to point to memout when appropri-
-ate inside backquotes.
-
-INPUT:  The basic input routine is pgetc, which reads from the
-current input file.  There is a stack of input files; the current
-input file is the top file on this stack.  The code allows the
-input to come from a string rather than a file.  (This is for the
--c option and the "." and eval builtin commands.)  The global
-variable plinno is saved and restored when files are pushed and
-popped from the stack.  The parser routines store the number of
-the current line in this variable.
-
-DEBUGGING:  If DEBUG is defined in shell.h, then the shell will
-write debugging information to the file $HOME/trace.  Most of
-this is done using the TRACE macro, which takes a set of printf
-arguments inside two sets of parenthesis.  Example:
-"TRACE(("n=%d0, n))".  The double parenthesis are necessary be-
-cause the preprocessor can't handle functions with a variable
-number of arguments.  Defining DEBUG also causes the shell to
-generate a core dump if it is sent a quit signal.  The tracing
-code is in show.c.

-.Dd May 31, 1993
-.Dt ECHO 1
-.Os
-.Sh NAME
-.Nm echo
-.Nd produce message in a shell script
-.Sh SYNOPSIS
-.Nm
-.Op Fl n | Fl e
-.Ar args ...
-.Sh DESCRIPTION
-.Nm
-prints its arguments on the standard output, separated by spaces.
-Unless the
-.Fl n
-option is present, a newline is output following the arguments.
-The
-.Fl e
-option causes
-.Nm
-to treat the escape sequences specially, as described in the following
-paragraph.
-The
-.Fl e
-option is the default, and is provided solely for compatibility with
-other systems.
-Only one of the options
-.Fl n
-and
-.Fl e
-may be given.
-.Pp
-If any of the following sequences of characters is encountered during
-output, the sequence is not output.  Instead, the specified action is
-performed:
-.Bl -tag -width indent
-.It Li \eb
-A backspace character is output.
-.It Li \ec
-Subsequent output is suppressed.  This is normally used at the end of the
-last argument to suppress the trailing newline that
-.Nm
-would otherwise output.
-.It Li \ef
-Output a form feed.
-.It Li \en
-Output a newline character.
-.It Li \er
-Output a carriage return.
-.It Li \et
-Output a (horizontal) tab character.
-.It Li \ev
-Output a vertical tab.
-.It Li \e0 Ns Ar digits
-Output the character whose value is given by zero to three digits.
-If there are zero digits, a nul character is output.
-.It Li \e\e
-Output a backslash.
-.El
-.Sh HINTS
-Remember that backslash is special to the shell and needs to be escaped.
-To output a message to standard error, say
-.Pp
-.D1  echo message \*[Gt]\*[Am]2
-.Sh BUGS
-The octal character escape mechanism
-.Pq Li \e0 Ns Ar digits
-differs from the
-C language mechanism.
-.Pp
-There is no way to force
-.Nm
-to treat its arguments literally, rather than interpreting them as
-options and escape sequences.

-.Sh NAME
-.Nm printf
-.Nd formatted output
-.Sh SYNOPSIS
-.Nm
-.Ar format
-.Op Ar arguments  ...
-.Sh DESCRIPTION
-.Nm
-formats and prints its arguments, after the first, under control
-of the
-.Ar format  .
-The
-.Ar format
-is a character string which contains three types of objects: plain characters,
-which are simply copied to standard output, character escape sequences which
-are converted and copied to the standard output, and format specifications,
-each of which causes printing of the next successive
-.Ar argument  .
-.Pp
-The
-.Ar arguments
-after the first are treated as strings if the corresponding format is
-either
-.Cm b ,
-.Cm B ,
-.Cm c
-or
-.Cm s ;
-otherwise it is evaluated as a C constant, with the following extensions:
-.Pp
-.Bl -bullet -offset indent -compact
-.It
-A leading plus or minus sign is allowed.
-.It
-If the leading character is a single or double quote, the value is the
-.Tn ASCII
-code of the next character.
-.El
-.Pp
-The format string is reused as often as necessary to satisfy the
-.Ar arguments  .
-Any extra format specifications are evaluated with zero or the null
-string.
-.Pp
-Character escape sequences are in backslash notation as defined in
-.St -ansiC .
-The characters and their meanings are as follows:
-.Bl -tag -width Ds -offset indent
-.It Cm \ee
-Write an \*[Lt]escape\*[Gt] character.
-.It Cm \ea
-Write a \*[Lt]bell\*[Gt] character.
-.It Cm \eb
-Write a \*[Lt]backspace\*[Gt] character.
-.It Cm \ef
-Write a \*[Lt]form-feed\*[Gt] character.
-.It Cm \en
-Write a \*[Lt]new-line\*[Gt] character.
-.It Cm \er
-Write a \*[Lt]carriage return\*[Gt] character.
-.It Cm \et
-Write a \*[Lt]tab\*[Gt] character.
-.It Cm \ev
-Write a \*[Lt]vertical tab\*[Gt] character.
-.It Cm \e\'
-Write a \*[Lt]single quote\*[Gt] character.
-.It Cm \e"
-Write a \*[Lt]double quote\*[Gt] character.
-.It Cm \e\e
-Write a backslash character.
-.It Cm \e Ns Ar num
-Write an 8\-bit character whose
-.Tn ASCII
-value is the 1\-, 2\-, or 3\-digit octal number
-.Ar num .
-.It Cm \ex Ns Ar xx
-Write an 8\-bit character whose
-.Tn ASCII
-value is the 1\- or 2\-digit hexadecimal number
-.Ar xx .
-.El
-.Pp
-Each format specification is introduced by the percent character
-(``%'').
-The remainder of the format specification includes,
-in the following order:
-.Bl -tag -width Ds
-.It "Zero or more of the following flags:"
-.Bl -tag -width Ds
-.It Cm #
-A `#' character
-specifying that the value should be printed in an ``alternative form''.
-For
-.Cm b ,
-.Cm c ,
-.Cm d ,
-and
-.Cm s
-formats, this option has no effect.
-For the
-.Cm o
-format the precision of the number is increased to force the first
-character of the output string to a zero.
-For the
-.Cm x
-.Pq Cm X
-format, a non-zero result has the string
-.Li 0x
-.Pq Li 0X
-prepended to it.
-For
-.Cm e  ,
-.Cm E ,
-.Cm f  ,
-.Cm g ,
-and
-.Cm G
-formats, the result will always contain a decimal point, even if no
-digits follow the point (normally, a decimal point only appears in the
-results of those formats if a digit follows the decimal point).
-For
-.Cm g
-and
-.Cm G
-formats, trailing zeros are not removed from the result as they
-would otherwise be.
-.\" I turned this off - decided it isn't a valid use of '#'
-.\" For the
-.\" .Cm B
-.\" format, backslash-escape sequences are expanded first;
-.It Cm \&\-
-A minus sign `\-' which specifies
-.Em left adjustment
-of the output in the indicated field;
-.It Cm \&+
-A `+' character specifying that there should always be
-a sign placed before the number when using signed formats.
-.It Sq \&\ \&
-A space specifying that a blank should be left before a positive number
-for a signed format.
-A `+' overrides a space if both are used;
-.It Cm \&0
-A zero `0' character indicating that zero-padding should be used
-rather than blank-padding.
-A `\-' overrides a `0' if both are used;
-.El
-.It "Field Width:"
-An optional digit string specifying a
-.Em field width ;
-if the output string has fewer characters than the field width it will
-be blank-padded on the left (or right, if the left-adjustment indicator
-has been given) to make up the field width (note that a leading zero
-is a flag, but an embedded zero is part of a field width);
-.It Precision :
-An optional period,
-.Sq Cm \&.\& ,
-followed by an optional digit string giving a
-.Em precision
-which specifies the number of digits to appear after the decimal point,
-for
-.Cm e
-and
-.Cm f
-formats, or the maximum number of characters to be printed
-from a string
-.Sm off
-.Pf ( Cm b No ,
-.Sm on
-.Cm B
-and
-.Cm s
-formats); if the digit string is missing, the precision is treated
-as zero;
-.It Format :
-A character which indicates the type of format to use (one of
-.Cm diouxXfwEgGbBcs ) .
-.El
-.Pp
-A field width or precision may be
-.Sq Cm \&*
-instead of a digit string.
-In this case an
-.Ar argument
-supplies the field width or precision.
-.Pp
-The format characters and their meanings are:
-.Bl -tag -width Fl
-.It Cm diouXx
-The
-.Ar argument
-is printed as a signed decimal (d or i), unsigned octal, unsigned decimal,
-or unsigned hexadecimal (X or x), respectively.
-.It Cm f
-The
-.Ar argument
-is printed in the style
-.Sm off
-.Pf [\-]ddd Cm \&. No ddd
-.Sm on
-where the number of d's
-after the decimal point is equal to the precision specification for
-the argument.
-If the precision is missing, 6 digits are given; if the precision
-is explicitly 0, no digits and no decimal point are printed.
-.It Cm eE
-The
-.Ar argument
-is printed in the style
-.Sm off
-.Pf [\-]d Cm \&. No ddd Cm e No \\*(Pmdd
-.Sm on
-where there
-is one digit before the decimal point and the number after is equal to
-the precision specification for the argument; when the precision is
-missing, 6 digits are produced.
-An upper-case E is used for an `E' format.
-.It Cm gG
-The
-.Ar argument
-is printed in style
-.Cm f
-or in style
-.Cm e
-.Pq Cm E
-whichever gives full precision in minimum space.
-.It Cm b
-Characters from the string
-.Ar argument
-are printed with backslash-escape sequences expanded.
-.br
-The following additional backslash-escape sequences are supported:
-.Bl -tag -width Ds
-.It Cm \ec
-Causes
-.Nm
-to ignore any remaining characters in the string operand containing it,
-any remaining string operands, and any additional characters in
-the format operand.
-.It Cm \e0 Ns Ar num
-Write an 8\-bit character whose
-.Tn ASCII
-value is the 1\-, 2\-, or 3\-digit
-octal number
-.Ar num .
-.It Cm \e^ Ns Ar c
-Write the control character 
-.Ar c .
-Generates characters `\e000' through `\e037`, and `\e177' (from `\e^?').
-.It Cm \eM\- Ns Ar c
-Write the character 
-.Ar c
-with the 8th bit set.
-Generates characters `\e241' through `\e376`.
-.It Cm \eM^ Ns Ar c
-Write the control character 
-.Ar c
-with the 8th bit set.
-Generates characters `\e000' through `\e037`, and `\e177' (from `\eM^?').
-.El
-.It Cm B
-Characters from the string
-.Ar argument
-are printed with unprintable characters backslash-escaped using the
-.Sm off
-.Pf ` Cm \e Ar c No ',
-.Pf ` Cm \e^ Ar c No ',
-.Pf ` Cm \eM\- Ar c No '
-or
-.Pf ` Cm \eM^ Ar c No ',
-.Sm on
-formats described above.
-.It Cm c
-The first character of
-.Ar argument
-is printed.
-.It Cm s
-Characters from the string
-.Ar argument
-are printed until the end is reached or until the number of characters
-indicated by the precision specification is reached; if the
-precision is omitted, all characters in the string are printed.
-.It Cm \&%
-Print a `%'; no argument is used.
-.El
-.Pp
-In no case does a non-existent or small field width cause truncation of
-a field; padding takes place only if the specified field width exceeds
-the actual width.
-.Sh EXIT STATUS
-.Nm
-exits 0 on success, 1 on failure.
-.Sh SEE ALSO
-.Xr echo 1 ,
-.Xr printf 3 ,
-.Xr printf 9
-.Xr vis 3
-.Sh STANDARDS
-The
-.Nm
-utility conforms to
-.St -p1003.1-2001 .
-.Pp
-Support for the floating point formats and `*' as a field width and precision
-are optional in POSIX.
-.Pp
-The behaviour of the %B format and the \e', \e", \exxx, \ee and
-\e[M][\-|^]c escape sequences are undefined in POSIX.
-.Sh BUGS
-Since the floating point numbers are translated from
-.Tn ASCII
-to floating-point and
-then back again, floating-point precision may be lost.
-.Pp
-Hexadecimal character constants are restricted to, and should be specified
-as, two character constants.  This is contrary to the ISO C standard but
-does guarantee detection of the end of the constant.

-.Sh NAME
-.Nm test ,
-.Nm \&[
-.Nd condition evaluation utility
-.Sh SYNOPSIS
-.Nm test
-.Ar expression
-.Nm \&[
-.Ar expression Cm ]
-.Sh DESCRIPTION
-The
-.Nm test
-utility evaluates the expression and, if it evaluates
-to true, returns a zero (true) exit status; otherwise
-it returns 1 (false).
-If there is no expression, test also
-returns 1 (false).
-.Pp
-All operators and flags are separate arguments to the
-.Nm test
-utility.
-.Pp
-The following primaries are used to construct expression:
-.Bl -tag -width Ar
-.It Fl b Ar file
-True if
-.Ar file
-exists and is a block special
-file.
-.It Fl c Ar file
-True if
-.Ar file
-exists and is a character
-special file.
-.It Fl d Ar file
-True if
-.Ar file
-exists and is a directory.
-.It Fl e Ar file
-True if
-.Ar file
-exists (regardless of type).
-.It Fl f Ar file
-True if
-.Ar file
-exists and is a regular file.
-.It Fl g Ar file
-True if
-.Ar file
-exists and its set group ID flag
-is set.
-.It Fl h Ar file
-True if
-.Ar file
-exists and is a symbolic link.
-.It Fl k Ar file
-True if
-.Ar file
-exists and its sticky bit is set.
-.It Fl n Ar string
-True if the length of
-.Ar string
-is nonzero.
-.It Fl p Ar file
-True if
-.Ar file
-is a named pipe
-.Po Tn FIFO Pc .
-.It Fl r Ar file
-True if
-.Ar file
-exists and is readable.
-.It Fl s Ar file
-True if
-.Ar file
-exists and has a size greater
-than zero.
-.It Fl t Ar file_descriptor
-True if the file whose file descriptor number
-is
-.Ar file_descriptor
-is open and is associated with a terminal.
-.It Fl u Ar file
-True if
-.Ar file
-exists and its set user ID flag
-is set.
-.It Fl w Ar file
-True if
-.Ar file
-exists and is writable.
-True
-indicates only that the write flag is on.
-The file is not writable on a read-only file
-system even if this test indicates true.
-.It Fl x Ar file
-True if
-.Ar file
-exists and is executable.
-True
-indicates only that the execute flag is on.
-If
-.Ar file
-is a directory, true indicates that
-.Ar file
-can be searched.
-.It Fl z Ar string
-True if the length of
-.Ar string
-is zero.
-.It Fl L Ar file
-True if
-.Ar file
-exists and is a symbolic link.
-This operator is retained for compatibility with previous versions of
-this program.
-Do not rely on its existence; use
-.Fl h
-instead.
-.It Fl O Ar file
-True if
-.Ar file
-exists and its owner matches the effective user id of this process.
-.It Fl G Ar file
-True if
-.Ar file
-exists and its group matches the effective group id of this process.
-.It Fl S Ar file
-True if
-.Ar file
-exists and is a socket.
-.It Ar file1 Fl nt Ar file2
-True if
-.Ar file1
-exists and is newer than
-.Ar file2 .
-.It Ar file1 Fl ot Ar file2
-True if
-.Ar file1
-exists and is older than
-.Ar file2 .
-.It Ar file1 Fl ef Ar file2
-True if
-.Ar file1
-and
-.Ar file2
-exist and refer to the same file.
-.It Ar string
-True if
-.Ar string
-is not the null
-string.
-.It Ar \&s\&1 Cm \&= Ar \&s\&2
-True if the strings
-.Ar \&s\&1
-and
-.Ar \&s\&2
-are identical.
-.It Ar \&s\&1 Cm \&!= Ar \&s\&2
-True if the strings
-.Ar \&s\&1
-and
-.Ar \&s\&2
-are not identical.
-.It Ar \&s\&1 Cm \&\*[Lt] Ar \&s\&2
-True if string
-.Ar \&s\&1
-comes before
-.Ar \&s\&2
-based on the ASCII value of their characters.
-.It Ar \&s\&1 Cm \&\*[Gt] Ar \&s\&2
-True if string
-.Ar \&s\&1
-comes after
-.Ar \&s\&2
-based on the ASCII value of their characters.
-.It Ar \&n\&1 Fl \&eq Ar \&n\&2
-True if the integers
-.Ar \&n\&1
-and
-.Ar \&n\&2
-are algebraically
-equal.
-.It Ar \&n\&1 Fl \&ne Ar \&n\&2
-True if the integers
-.Ar \&n\&1
-and
-.Ar \&n\&2
-are not
-algebraically equal.
-.It Ar \&n\&1 Fl \&gt Ar \&n\&2
-True if the integer
-.Ar \&n\&1
-is algebraically
-greater than the integer
-.Ar \&n\&2 .
-.It Ar \&n\&1 Fl \&ge Ar \&n\&2
-True if the integer
-.Ar \&n\&1
-is algebraically
-greater than or equal to the integer
-.Ar \&n\&2 .
-.It Ar \&n\&1 Fl \&lt Ar \&n\&2
-True if the integer
-.Ar \&n\&1
-is algebraically less
-than the integer
-.Ar \&n\&2 .
-.It Ar \&n\&1 Fl \&le Ar \&n\&2
-True if the integer
-.Ar \&n\&1
-is algebraically less
-than or equal to the integer
-.Ar \&n\&2 .
-.El
-.Pp
-These primaries can be combined with the following operators:
-.Bl -tag -width Ar
-.It Cm \&! Ar expression
-True if
-.Ar expression
-is false.
-.It Ar expression1 Fl a Ar expression2
-True if both
-.Ar expression1
-and
-.Ar expression2
-are true.
-.It Ar expression1 Fl o Ar expression2
-True if either
-.Ar expression1
-or
-.Ar expression2
-are true.
-.It Cm \&( Ns Ar expression Ns Cm \&)
-True if expression is true.
-.El
-.Pp
-The
-.Fl a
-operator has higher precedence than the
-.Fl o
-operator.
-.Sh GRAMMAR AMBIGUITY
-The
-.Nm test
-grammar is inherently ambiguous.
-In order to assure a degree of consistency, the cases described in
-.St -p1003.2
-section 4.62.4,
-are evaluated consistently according to the rules specified in the
-standards document.
-All other cases are subject to the ambiguity in the command semantics.
-.Sh EXIT STATUS
-The
-.Nm test
-utility exits with one of the following values:
-.Bl -tag -width Ds
-.It 0
-expression evaluated to true.
-.It 1
-expression evaluated to false or expression was
-missing.
-.It \*[Gt]1
-An error occurred.
-.El
-.Sh STANDARDS
-The
-.Nm test
-utility implements a superset of the
-.St -p1003.2
-specification.
