I have a script called ask_input.pl which basically asked for an input. Below is the script. 
#!/usr/bin/perl

use strict;

print "Enter your answer?\n";    # Line 3
<>;                              # Line 4
print "Done.\n";

So, when I call this script from the command line, it should ask for the input.

Now, when I call this script from another script or is run through the cron, it should bypass the lines where it asks for the inputs specifically lines 3 and 4. I was thinking of using GetOpt::Long to add an argument in the ask_input.pl script, and if that particular argument exists then it will just bypass lines 3 and 4.

Is this the efficient way to do this? What are the other ways of doing this? I read somewhere but could not recall that a Perl module can be run as both as a module and as a stand-alone script. I'm not sure if I can use this in this situation though.
