threads in ksh script
Hi Unix Gurus,
Please guide me on how to simulate threads in korn-shell scripting. I am new to ksh scripting.

What I want is a simple 2 liner code to create two threads and then run two parallel jobs in these two threads at the same time. Also please tell me how to catch the return code in each of these threads.

As far as I know threads are not there in ksh, but I heard creating a sub-shell would create the effect.
Please guide.
Thanks

I think you must mean coprocesses. Search the forums for coprocess, there are a lot of examples.

Code:
command1 & p1=$!
command2 & p2=$!

wait $p1; r1=$?
wait $p2; r2=$?

echo r1=$r1
echo r2=$r2
