What I meant by exit code is the value of $?.
Under normal circumstances, like a successfully run command, the exit code will be 0. If there's an error, it will be something else. The sample script above checks to make sure that $? = 0, and if not, it will send an email.
The concern I have is that something in whatever script is run may run successfully after the failed command... I don't know if I'm explaining very well, so I'll try to show you:
Code:
$ cat tmp1.sh
#!/bin/sh
echo
wuzzle
$ ./tmp1.sh
./tmp1.sh: wuzzle: command not found
$ echo $?
127
$ cat tmp2.sh
#!/bin/sh
wuzzle
echo
$ ./tmp2.sh
./tmp2.sh: wuzzle: command not found
$ echo $?
0
So, you see, unless you told the fullback script to "exit 1" (or exit anything not equal to 0) after any component failed, it might not email you if it does fail.
It depends completely on your script (the fullback.ksh one), is should be easy to make sure it does this correctly...
On the other hand, if you're going to be rewriting to do this, why not put them all together into one? Here's a very simple example:
Code:
#!/usr/bin/ksh
/bin/tar vcf /dev/rmt/0 /home/admin >/var/adm/backup_log 2>&1
if [[ $? -ne 0 ]]; then
/bin/mail admin <<EndOfMail
Subject: Your backup had errors
See the contents of /var/adm/backup_log
for more details.
.
EndOfMail
fi
I guess it all depends on what you're trying to do.
And please let me know if I don't make any sense... I'm kind of tired here

I added a shell script to cron that executes every 5-15 minutes. It's used to monitor multiple environments, so it has to ssh to each machine to check the status of that machine. Sometimes, I may have more than one instance of this script running at the same time. So, here's my problem. I've... (2 Replies)
