Re: Command Line Arg contains Variable and more

Not sure this will work in every arg passed

Also, doing something like this is probably not the safest

#!/usr/bin/perl

use warnings;
use strict;

my $string = $ARGV[0];

#print "$string";

my $rc = `$string`;
print $rc;

Changing `system $cmd;` [download] to print `$cmd`; [download] is never a good idea. All it does is introduce memory overhead and lag. It definitely doesn't help the OP interpolate a Perl variable into a shell command.	[reply] [d/l] [select]
