Change this:
To something like this.
The $? variable cannot be "reused" the way you did - store it in a variable instead. Once the if gets evaluated $?
Plus, the wait command [no argument ] will wait for all children.
If a child fails, wait returns the exit code of the child which, in theory, can be any number (1-255) except 0.
So, you can safely check for a non-zero return.
Also note this important fact: rm removes the directory entry for a file that is open by another process, when that other process exits the physical file is removed from the file system.
A hung child process in a lockfile design can make the script fail and confuse the heck out of you.

Hi,
I have written a some six scripts to move large files and re-size them. This has been done step by step, taking backup, creating the new files, merging the files, removing the temporary files created.
Since these files are around 500 MB, each step takes somewhere between 1 to 5 mins.

I've been bitten by using a lock or pid file to prevent multiple instances of a script. A user typed kill -9, and the pid file didn't go away. You can't trap -9. So when he tried to restart, it said "already running", and I got trouble report. Argh.
So here's what we came up with:

uudemon
uudemon(4) Kernel Interfaces Manual uudemon(4)NAME
uudemon.admin, uudemon.cleanu, uudemon.hour, uudemon.poll - Administrative shell scripts for polling remote systems, cleaning up spool
directories, reporting status to the system administrator, and routine invocations of the uuxqt and uusched daemons
SYNOPSIS
These shell scripts reside in the following directory:
/usr/lib/uucp
DESCRIPTION
All the scripts can be run from the command line or can be run automatically by the cron daemon. To automatically run the scripts, remove
the comment character (#) from the beginning of the relevant line in the /var/spool/cron/crontabs/uucp file.
This script reports status to the system administrator. It issues the uustat command to find out the status of uucp jobs. It mails the
results to the uucp login ID. The script may be modified to send mail to any login ID such as the uucp administrative login ID (uucpa) or
root. This script cleans up the /var/spool/uucp and /var/spool/uucppublic directories by running the uucleanup command. The uucleanup com-
mand is run with the following parameters: -C7, -D7, X2, -o2, -W1. This script runs the uusched and uuxqt daemons in the background. This
script polls the systems listed in the /usr/lib/uucp/Poll file. The uudemon.poll script should be scheduled before the uudemon.hour
script. This allows uudemon.poll to create any command files before cron runs the uudemon.hour script.
FILES
Contains the uudemon.admin, uudemon.cleanu, uudemon.hour and uudemon.poll files. Contains the uucp file.
RELATED INFORMATION
Commands: cron(8), uucleanup(8), uusched(8), uuxqt(1)
