Subject: 'emulate sh -c' and $0
Date: Thu, 29 May 2014 19:04:45 -0400 [thread overview]
Message-ID: <5387BD0D.8090202@bbn.com> (raw)
Hi all,
I just encountered what I think is a bug in Zsh 5.0.5. The following
command:
zsh -c '
emulate sh -c "echo \"\$0\""
bar() { emulate sh -c "echo \"\$0\""; }
bar
' foo arg1
produces the following output:
foo
bar
I expected it to produce:
foo
foo
This is relevant when sourcing a file containing (POSIX) sh code that
might examine $0 (e.g., for logging or to 'exec "$0" "$@"' after
exporting/unsetting environment variables).
Perhaps Zsh should save the original value of $0 somewhere and restore
it when entering sh emulation mode.
Thanks,
Richard
