sh -ce

[Marc Pawliger]

The man page for sh and ksh say the -e flag causes immediate exit if a command
fails.  Does this also apply for builtins?  And what about the exit status?

I have seen vastly differing behavior for the following:

  /bin/sh -ce 'cd nonexistantdirectory; pwd'

Some Bourne shells exit after the bad cd with status 0, some exit with status
1.  Some don't exit after the bad cd, presumably because it's a builtin.
/bin/sh -ce '/bin/ls nonexistantdirectory; pwd' always exited after the ls
with status 1.

Please also reply by mail if you are following-up in this group...
