retrieving exit status from background processes

Hi,

I need to retrieve the exit status of 4 moves running as background processes. The wait command will not work since it can only give me the exit status of the last of the background processes.

Here's a sample of what I need

!#/bin/ksh

mv /dir1/subdir1/*.Z /dir6/subdir6/ &
mv /dir2/subdir2/*.Z /dir7/subdir7/ &
mv /dir3/subdir3/*.Z /dir8/subdir8/ &
mv /dir4/subdir4/*.Z /dir9/subdir9/ &
wait


I want the exit status of each and every one of my moves listed above.

Thanks...

As you launch each background process, save $! which is the pid of the background process. After you launch all 4 you will have a list of 4 pid's. Now one by one wait for each pid, with "wait $pid". The man page does make it clear that this works, and the korn shell book does.

Thank you

Sometimes the answer stares you right in the face and you just can't see it.

I was under the impression that the only valid exit status returned would be the one from the longest running background process.

Thanks again.
