How to track the pid of a background child process(shell script) from a parent script ?

For example :-

$ sleep 10000 &
[1] 4220

where 4220 is the pid of bg process sleep.

Now my requirement is to keep the sleep statement in a shell script(test.ksh) and will be invoking it from another shell script (test2.ksh).

Is there any way to get the pid of test.ksh (child background process) from test2.ksh?

ram...
when u r creating the script test2.ksh, immeditaely after you call test.ksh you could give ID=$$
ID being just another variable, $$ would give the PID of the last process you have run.

$! is the pid of the most recent process, $$ is the pid of the current process, $PPID is the parent pid. In Korn shell.
