Check the exit codes of each command as they complete. Then set the
exit code of your script to something that you can translate back to the
failed command:
i.e.
-----------
integer RETURN=0
tar -cf /tarballs/mytar.tar /stuff/to/tar
if [ $? -ne 0 ]; then
RETURN=123 # I will know that an exit of 123 means a problem with the
tar
fi
<other commands>
if [ $RETURN -ne 0 ]; then
echo "error message" | mail -s "problems" me@foobar.com
fi
exit $RETURN
-----------
The only problem with this method is that if more than one command
fails, it will only report that last one. You code do something with
adding the return codes together (i.e. command #1 = 0 or 1, command #2 =
00 or 10) I don't know (off hand) what the limitation is for the
ceiling on exit codes.

Subject: graceful script exit
If I have a script with does a number of things like tars, copy
commands,
etc. What is the best way to generate a flag if a SINGLE command in the
script fails? In other words, if I'm thinking about this correctly, I
want
to get a page when the script is finished, and one command didn't finish
correctly, even if some of the commands have succeeded. Thanks!
