nine9 has asked for the wisdom of the Perl Monks concerning the following question:

Newbie-type question

I'm really new to Perl and I was wondering if it's possible to "chain" execution of perl progs, i.e. to have one program call another, and when the child program is finished have control return to the parent...?

    The system call does exactly that. All you have to do is something like system 'program_name';

    depending on your system you have to call it like system('/usr/bin/perl script_name'); be careful because that command will wait for the program to exit. If you want to chain them, best to either wrap them with a shell script or add an '&' to run the next in the background that way the first script can exit
