problem in finding matching string

[pnsreee]

Hi All,

I have the following strings seperated by space . I have to grep for Naveen having two values(Sha or See) in the string.

1)Naveen Sha reswww
2)Naveen See rex-www
3)Naveen See rex.x
4)Naveen xxxx cccccc
5)ABBCD See reggg
I have the following regexp.
$_ =~ /^Naveen[\s](Sha|See)[\s][.....]+$/

I want the first three strings above mentioned as output,

when I replace [.....] in regexp with [\d|\w], I am getting the first string as my output. but i need first three strings as an output.

Please help me regarding this.

Regards
Pnsreee

As per my understanding you wana to grep first three string if it has naveen in it right.

Here is the solution :

$_=~/^(Naveen)\s+(Sha|She)\s+(\w+).+?/;

First, I would REALLY suggest that you go down to your local Barnes & Nobles store and pick up a copy of "Mastering Regular Expressions". That will greatly help you in better understanding regex's. The regex you supplied above is very messy and has a lot of mistakes. One right off the bat that stood out to me was your use of [ and ]. The square brackets typically dictate that the regex should match one of the characters held between them.

Now, taking your requirements, I came up with the following code that does what you wanted to do:

use strict;
use warnings;
 
my $file = 'naveen.txt';
open(FILE, $file) or die "Can't open $file: $!";
 
while (<FILE>) {
    chomp;
    my $line = $_;
 
    if ($line =~ m/^Naveen\s+(?:Sha|See)\s+\w+[-.]*\w/) {
        print "$line\n";
    }
}
 
close(FILE);
 

I suggest you get the book and examine the regex above and learn to write cleaner, more exact regex's or you will have problems down the line in Perl. Just a suggestion.
