Can grep be used on a Perl variable?
- by Structure
Is it possible one way or another to, within a Perl script, effectively execute grep against a Perl variable? An equivalent Perl function would be equally acceptable, I just want to keep the solution as simple as possible.
For example:
#!/usr/bin/perl
#!/bin/grep
$var="foobar";
$newvar="system('grep -o "foo" $var');
sprintf $newvar;
Where I expect sprintf $newvar to output foo.
Would also welcome any feedback on best practice here. I am not extremely familiar with Perl.
