Re^2: searching several files for a string at one time

but how do I make it so the users can select the directory when the programme is ran?

One way is to pass it in on the command line (see shift):

use strict;
use warnings;

my $directory = shift;
print "dir=$directory\n";   # just for debug

Run your program as:

$ ./838783.pl /foo/bar
dir=/foo/bar
