Shell Programming and Scripting

Greets all. I'm using Slackware 12.0 with the bash shell. Calling my scripts with /bin/sh...

I'm building gnome-2.18.3 and I have all my build scripts ready and working but I'm calling them from a parent script which executes each child/build script in a certain order (for loop).

I have "set -e" in each child script but the parent keeps right on going if a child craps out. What's the quickest/easiest way to get the parent to exit on child failure?

Thanks everyone. Been looking high and low but can't seem to find the information I need and error trapping is pretty new to me.

Either test the return code $? of the child or set -e in the parent.

Sorry, forgot to mention that I do have "set -e" in my parent. Doesn't seem to be working. Sorry for my ignorance but could you possibly give an example of how to test the return code of a child?

Thanks for your help.

Here's two ways, there are others.

Code:

childcommand || exit 1

Code:

childcommand
if [[ $? -ne 0 ]] ; then
   exit 1
fi

I knew about the || exit 1 bit. Thanks for reminding me. However, it still doesn't work. I'm confounded.

That's my parent script. All of the new/*-*/*.build scripts are the children. 10:1 it's the way I'm implementing my commands. wrapping them in ( ) or something.

Sorry for the bother.

Uhh.. My previous reply is waiting on moderator aproval for some reason but I found the problem. I was wrapping my commands in parenthesis else I wouldn't return to "pwd" for the next package in line. Wrapping your commands like that somehow borks the error trapping. It's fixed now.

Thanks reborg for your help. I really appreciate it.

Hi everyone,
while searching for our problem I found this thread, but we are still struggling. Help would be lovely.

We have:

#!/bin/sh

while read blabla
do
. childscript

rc=$?
if [[ $rc -gt 0 ]]
then
blabla
exit 4
fi

Childscript falls over, does 'exit 4' but $? is still empty....
Any ideas?

Thanks!!

Cheers,
