Hi,
I have a question about grepping a file to match a regex, and then using the "match" as a variable in some other function.
The code I have so far is:
#!/usr/bin/perl
use strict;
use warnings;
my $file = "./file.txt";
# File data looks like: (without the beginning hash)
# tag: variable
open(FILE, $file);
if ( grep /^tag\: (.*)$/, <FILE> ) {
print "Found tag: $1\n";
} # end-if
close(FILE);
exit;
My question is, how can i use what the match of (.*) was? $1 is not it.
Any help would be appreciated.
Cheers,
Reagen
Update: Sorry, looks like some more info is needed.
There could be 0 or 1 matches in the file (i.e. either there is a tag and value or there isnt).
