-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 -character 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 the -.St -ansiC , -with extensions. -The characters and their meanings -are as follows: -.Pp -.Bl -tag -width Ds -offset indent -compact -.It Cm \ea -Write a <bell> character. -.It Cm \eb -Write a <backspace> character. -.It Cm \ef -Write a <form-feed> character. -.It Cm \en -Write a <new-line> character. -.It Cm \er -Write a <carriage return> character. -.It Cm \et -Write a <tab> character. -.It Cm \ev -Write a <vertical tab> character. -.It Cm \e\' -Write a <single quote> character. -.It Cm \e\e -Write a backslash character. -.It Cm \e Ns Ar num -Write a byte whose -value is the 1-, 2-, or 3-digit -octal number -.Ar num . -Multibyte characters can be constructed using multiple -.Cm \e Ns Ar num -sequences. -.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 ``alternate form''. -For -.Cm b , c , d , s -and -.Cm u -formats, this option has no effect. -For the -.Cm o -formats 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 a , A , e , E , f , F , 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; -.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 bytes 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 bytes to be printed -from a string; 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 diouxXfFeEgGaAcsb ) . -The uppercase formats differ from their lowercase counterparts only in -that the output of the former is entirely in uppercase. -The floating-point format specifiers -.Pq Cm fFeEgGaA -may be prefixed by an -.Cm L -to request that additional precision be used, if available. -.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 fF -The -.Ar argument -is printed in the style `[\-]ddd.ddd' 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. -The values \*[If] and \*[Na] are printed as -.Ql inf -and -.Ql nan , -respectively. -.It Cm eE -The -.Ar argument -is printed in the style -.Cm e -.Sm off -.Sq Op - Ar d.ddd No \(+- Ar dd -.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. -The values \*[If] and \*[Na] are printed as -.Ql inf -and -.Ql nan , -respectively. -.It Cm gG -The -.Ar argument -is printed in style -.Cm f -.Pq Cm F -or in style -.Cm e -.Pq Cm E -whichever gives full precision in minimum space. -.It Cm aA -The -.Ar argument -is printed in style -.Sm off -.Sq Op - Ar h.hhh No \(+- Li p Ar d -.Sm on -where there is one digit before the hexadecimal point and the number -after is equal to the precision specification for the argument; -when the precision is missing, enough digits are produced to convey -the argument's exact double-precision floating-point representation. -The values \*[If] and \*[Na] are printed as -.Ql inf -and -.Ql nan , -respectively. -.It Cm c -The first byte of -.Ar argument -is printed. -.It Cm s -Bytes from the string -.Ar argument -are printed until the end is reached or until the number of bytes -indicated by the precision specification is reached; however if the -precision is 0 or missing, the string is printed entirely. -.It Cm b -As for -.Cm s , -but interpret character escapes in backslash notation in the string -.Ar argument . -The permitted escape sequences are slightly different in that -octal escapes are -.Cm \e0 Ns Ar num -instead of -.Cm \e Ns Ar num -and that an additional escape sequence -.Cm \ec -stops further output from this -.Nm -invocation. -.It Cm n$ -Allows reordering of the output according to -.Ar argument . -.It Cm \&% -Print a `%'; no argument is used. -.El -.Pp -The decimal point -character is defined in the program's locale (category -.Dv LC_NUMERIC ) . -.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. -.Pp -Some shells may provide a builtin -.Nm -command which is similar or identical to this utility. -Consult the -.Xr builtin 1 -manual page. -.Sh EXIT STATUS -.Ex -std -.Sh COMPATIBILITY -The traditional -.Bx -behavior of converting arguments of numeric formats not beginning -with a digit to the -.Tn ASCII -code of the first character is not supported. -.Sh SEE ALSO -.Xr builtin 1 , -.Xr echo 1 , -.Xr sh 1 , -.Xr printf 3 -.Sh STANDARDS -The -.Nm -command is expected to be compatible with the -.St -p1003.2 -specification. -.Sh HISTORY -The -.Nm -command appeared in -.Bx 4.3 Reno . -It is modeled -after the standard library function, -.Xr printf 3 . -.Sh CAVEATS -.Tn ANSI -hexadecimal character constants were deliberately not provided. -.Pp -Trying to print a dash ("-") as the first character causes -.Nm -to interpret the dash as a program argument. -.Nm -- -must be used before -.Ar format . -.Pp -If the locale contains multibyte characters -(such as UTF-8), -the -.Cm c -format and -.Cm b -and -.Cm s -formats with a precision -may not operate as expected. -.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. -(By default, the number is translated to an IEEE-754 double-precision -value before being printed. -The -.Cm L -modifier may produce additional precision, depending on the hardware platform.) -.Pp -The escape sequence \e000 is the string terminator. -When present in the argument for the -.Cm b -format, the argument will be truncated at the \e000 character. -.Pp -Multibyte characters are not recognized in format strings (this is only -a problem if -.Ql % -can appear inside a multibyte character). |
