* [MAN] Clarify "trap '' signals" syntax in manual pageJonathan Nieder2014-09-26
| | | | | | | | | | | | | When the manpage states | <action> may be null, which cause the specified signals to be ignored. it is not immediately obvious what it means for an action to be null. Clarify by explicitly referring to an empty string, as opposed to a NULL pointer or the string "null".

* [MAN] 0 and EXIT both work for exit trapsAdam Buchbinder2014-09-26
| | | | | | | | | I saw a discussion in which there was some confusion over whether or not you can use a symbolic name, since the manpage doesn't specifically say so.

Indeed and this patch makes that change. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* [MAN] Markup fixes in manual for mandoc 1.12.1Jérémie Courrèges-Anglas2013-08-23
| | | | | | | | | with Aleksey we briefly discussed the mdoc compatibility of the manpage, here's a patch that makes mandoc 1.12.1 happier and behaves correctly against groff 1.21. I want to include it in the staging dash-0.5.7 OpenBSD port. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* [MAN] Fix typo for waitKimo Rosenbaum2013-08-23
| | | | | | This is a small patch to fix the paragraph about 'wait' in the dash manpage. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* [BUILTIN] Add support for ulimit -rChristoph Mathys2012-07-03
| | | | | | | | I recently found myself in need to have dash support 'ulimit -r' to set maximum realtime priority. Attached is a patch that adds the parameter to the builtin ulimit command and updates the manpage. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* [MAN] Remove spurious space in descriptions of PS1, PS2, PS4Kalle Olavi Niemitalo2011-07-07
| | | | | | | | | | | | | | | | | | | | | From: Kalle Olavi Niemitalo <kon@iki.fi> LANG=C man dash shows: PS1 The primary prompt string, which defaults to ``$ '', unless you are the superuser, in which case it defaults to ``# ''. PS2 The secondary prompt string, which defaults to ``> ''. PS4 Output before each line when execution trace (set -x) is enabled, defaults to ``+ ''. Each of the documented default values has a graphic character and two spaces between the quotation marks. However, the actual default values have only one space, rather than two.

* [MAN] Document optional open parenthesis for case patternsPhilipp Weis2010-11-28
| | | | | | | | | | While inspecting some dash scripts on my system, I was surprised to see that some of them use an open parenthesis at the beginning of case patterns while that's not mentioned in the manpage. Dash currently is fine with and without that parenthesis (parser.c:413). The attached patch documents this feature. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* [MAN] Update manual page to differentiate dash from ashGerrit Pape2009-05-23
| | | | | | | | | | | | Rename sh to dash in the header and synopsis; remove reference to the 4.4 BSD release in the description, and replace the history information with a reference to NetBSD's ash.

* [MAN] Removed obsolete for loop syntaxHerbert Xu2008-10-17
| | | | | | | | Sven Mascheck reported that we no longer accept the non-standard for {} syntax but the manual page still refers to it. This patch removes that reference. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* [MAN] Added missing right parenthesisGerrit Pape2008-07-13
| | | | | | | | | | | | | | In section Redirection the following text misses a left brace: where redir-op is one of the redirection operators mentioned previously. Following is a list of the possible redirections. The [n] is an optional number, as in \u20183\u2019 (not \u2018[3]\u2019, that refers to a file descriptor.

* [OPTIONS] Added support for -lHerbert Xu2008-07-13

* [BUILTIN] Add set +o supportRichard M Kreuter2007-12-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The dash(1) in Debian stable does not support "set +o" in the manner specified by SUSv3: |+o | Write the current option settings to standard output in a format | that is suitable for reinput to the shell as commands that | achieve the same options settings. (citation from http://www.opengroup.org/onlinepubs/009695399/utilities/set.html) Instead, dash's "set +o" prints the shell's options in a human-readable format. Here is a simple test program that exercises this feature; it works as I believe is required under bash, but not under dash. # Save the shell's options set +o > /tmp/settings-commands set -o | sort > /tmp/settings-before # Change some options. set -v set -f set -x set +o emacs set -o vi # Try to restore our options. . /tmp/settings-commands set -o | sort > /tmp/settings-after # Compare. diff /tmp/settings-before /tmp/settings-after I believe the following small patch adds this feature to dash, and documents it in the manual page: Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* [MAN] Clarify syntax of the for commandGerrit Pape2007-09-25
| | | | | | | | Document that in a for loop 'in word ...' is optional, and if omitted, 'in "$@"' is used. Lars Wilke noticed this, and reported through http://bugs.debian.org/387441
* [MAN] Clarify description of -nt, -ot options to test builtinGerrit Pape2007-09-25
| | | | | | | | | Have the man page explicitely state how the test builtin behaves on -nt and -ot options if file2 does not exist. The case where file1 does not exist was already documented properly. This was noticed by Sven Mueller and reported through http://bugs.debian.org/373611
* Copyright/licence updates and remove all traces of sys/cdefs.hHerbert Xu2005-10-29
| | | | | | | | | | | This change updates the BSD licence to the three-clause version since NetBSD has already done so. This makes dash GPL-compatible. It also adds Christos Zoulas (NetBSD ash maintainer) to the COPYING file. I've added "copyright by Herbert Xu" to most files. Finally all CVS IDs and inclusion of sys/cdefs.h have been removed. The latter is needed for support of klibc.
