Question

How do you send commands to the terminal in a perl script?

For example, if I want to run the command mkdir $directory in the console, what do I type in the perl script?

Answer 1

Modeling off the sample code in the documentation at http://perldoc.perl.org/functions/system.html:

@args = ("mkdir", $directory);
system(@args) == 0
    or die "mkdir failed";

Perl can make directories without system() calls, but I assume you want to do other things and are just using mkdir as an example.
