Subject: bug: $? after empty command
Date: Thu, 9 Jul 2009 13:12:20 +0000 (UTC) [thread overview]
Message-ID: <loom.20090709T130223-845@post.gmane.org> (raw)
POSIX requires that the execution of an empty command change $? to 0, as shown
here with bash:
$ zsh -c 'foo=; false; $foo; echo $?'
1
$ bash -c 'foo=; false; $foo; echo $?'
0
