Description Jinxin Zheng 2010-06-01 22:14:25 EDT
+++ This bug was initially created as a clone of Bug #597145 +++

Description of problem:
Issueing the 'help' command in guestfish with an unknown command name exits 
with a 0 exit code.

Version-Release number of selected component (if applicable):
guestfish 1.3.17

How reproducible:

Steps to Reproduce:
1. guestfish help foo
2. echo $?
Actual results:
the exit status of guestfish is 0

Expected results:
supposed to be some other than 0 to indicate an error.

Additional info:
I wanted to use help to test the availability of some new commands in a script, 
finding that it's impossible to determine only from the exit status of guestfish.
Therefore I must test the stderr in order to work the result out.

Patch posted upstream:

Please clone this bug if you want this in RHEL 5/6.  It's a relatively
simple change to backport.

Comment 8 Jinxin Zheng 2010-07-16 01:09:42 EDT
# guestfish help launch >/dev/null 
# echo $?

# guestfish help help >/dev/null 
# echo $?

# guestfish help blahblah >/dev/null 
blahblah: command not known, use -h to list all commands
# echo $?

guestfish help with non-existent command returns with the exit status 1, so move this bug to VERIFIED.
