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

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
