Hi,
ksh version: sh (AT&T Research) 93t+ 2009-05-01
OS: Red Hat Enterprise Linux AS release 4 (Nahant Update 5)
I am doing some work that requires tracking background jobs in a shell.
I earlier versions of ksh the command "jobs -ln" would print out the process
id(s) of the job(s) that had ended, so I would parse the output
and in a for loop to pass the process id(s) to wait, to check the exit
status.
But in this release I have found that "jobs -ln" does not include the
process id.
Cut down example of what I mean:
set -o monitor
trap checkbg CHLD
function checkbg
{
jobs -ln
}
sleep 10 &
wait
exit 0
This prints out;
"[1] + Done <command unknown>"
Is this correct or is there something else I have to do to get the process
id from the jobs command?
Is there a better way to check the exist status from a bunch of background
jobs in a script?
Thanks
Pete
