Shell Programming and Scripting

I have a sript which is going to trigger other 3 scripts in background simultaneously

for eg:

Main Script:(main.sh)
-----------
sh a.sh &
sh b.sh &
sh c.sh &

How to catch the exit status and store it in a variable for all those three scripts in main script. Is there any other way of triggering the scripts simulataneously in background.

Thanks in advance for your answers.

You can use log files ( output mode or error mode ) for redirecting exit code. For example,

#!/bin/sh
#a.sh
...
echo "1"
exit 1

..
echo "0"
exit 0
##

Execute this as,
sh a.sh 1>/tmp/ash.log 2>/dev/null &

It will do the trick.

Hi Muthukumar,

Thanks for your help, but where is the exit status.

What about something like...

Code:

#!/bin/ksh
./a.sh &
pid_a=$!
./b.sh &
pid_b=$!
./c.sh &
pid_c=$!
wait $pid_a
echo "a.sh returned $?"
wait $pid_b
echo "b.sh returned $?"
wait $pid_c
echo "c.sh returned $?"
