From 1b212d313de17ce3fbe0441b4269e2bf47b2dd68 Mon Sep 17 00:00:00 2001 From: Richard M Kreuter Date: Sun, 23 Dec 2007 11:24:48 +0800 Subject: [BUILTIN] Add set +o support 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 --- ChangeLog | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'ChangeLog') diff --git a/ChangeLog b/ChangeLog index e72849c..10ec45c 100644 --- a/ChangeLog +++ b/ChangeLog @@ -1,3 +1,7 @@ +2007-12-23 Richard M Kreuter + + * Add set +o support. + 2007-12-23 Steve Langasek * Fixed bad pointer arithmetic in evalcommand. -- cgit 1.4.1
