Propagate exist status from a child shell script to a parent.
Hi All,
I have a parent shell script A and a child shell script B.
1). If a command i.e a mysqdump fails in shell script B fails then I trap the error with this code
the func_exit writes various messages to log and calls exit 1
2). The parent script A called script B and also monitors the return status in the same way as above. However, the func_exit possess the following code:
For some reason the func_exit in script A is not being called on a failure in script B. Hence I don't get an email.
Please could anyone advise if the exit status propagation between the parent and child script is correct. I am using Debian.
Many thanks for your help.
Where is the wait statement in the parent process? I do not see one.
The parent creates the child, then (immediately or a little later) waits for the child. That is how the parent process knows about the child's exit status.
I have requirement where I need to fail parent if any one of the child process fails. Here is the code snippet
for i in 1 2 3 4 5 6 7 8 9 10
do
child_script $i &
done
wait
