The description of getops in the manual incorrectly states that
var will be set to "--" when no arguments remain. In fact it
will be set to "?".

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".

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.

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.

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.

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.

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.

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.

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.

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.

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:

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 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.
