Hi Monks,

I need of some suggestion to grep more than one pattern on a file content. I have set of patterns in a array, if any of the pattern matches I need to return that line.

I tried the following code it works fine.

use strict;
use warnings;
use Data::Dumper;

my @PatternList= qw(index: start:);

open(FH, "<", "test.txt") or die;
my $line;
my @Matches;

while($line=<FH>)
{
        my $pattern;
        foreach $pattern (@PatternList)
        {
                if ($line =~ /$pattern/)
                {
                        print "$line";
                }
        }
}

Is there any efficient way to do this? because I have more files to match the patterns

I tried the same with grep, as following but I am getting only the pattern, but not the matched lines, Do I missing something here with grep?

my @Matches = grep { /$_/, $line } @arr; #get the pattern not the matc
+hed line
