How to stop csh script in even of error

[Fred Ma]

Hi,

I am executing a bunch of cascaded (pipelined) commands
in a subshell within a csh script. These pipelined commands
include tarring up stuff and gzipping the resulting
output stream. If there is a problem, such as a "disk
full" error, i would like the csh script to stop
rather than finish the rest of the script. Is there a
way to make this happen? The I searched the csh man pages
for the work "rror" (as in "Error" or "error"), but there
is no mention of how to do this. Please copy all replies
to this account. Thanks.

If a properly-written command fails, it should set it's return value
to non-zero. In csh, you can test this by testing $status after you
run the command, or by running the command within the 'test' program.
(check 'man test') and testing for a non-zero value.
