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.

For example :-

$ sleep 10000 &

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?

NAME
times - shell built-in function to report time usages of the current shell SYNOPSIS
sh times ksh times DESCRIPTION
sh Print the accumulated user and system times for processes run from the shell. ksh Print the accumulated user and system times for the shell and for processes run from the shell. On this man page, ksh(1) commands that are preceded by one or two * (asterisks) are treated specially in the following ways: 1. Variable assignment lists preceding the command remain in effect when the command completes. 2. I/O redirections are processed after variable assignments. 3. Errors cause a script that contains them to abort. 4. Words, following a command preceded by ** that are in the format of a variable assignment, are expanded with the same rules as a vari- able assignment. This means that tilde substitution is performed after the = sign and word splitting and file name generation are not performed. ATTRIBUTES
