Re: how to find particular string and store in to variable

[marto]

This is a fairly simple problem, a reasonably common task regardless of programming language. Of course there is always more than one way to do it. Please note, the following is not a criticism but an observation, since you had to ask how to achieve this the suggestion a regex may be beyond your abilities at the moment. See xkcd://1171, I'll leave the background reading to you.

In the interest of keeping things very simple and presenting alternatives, below is an example using only perl built-ins, so not relying on an external module or regular expressions:

#!/usr/bin/perl

use strict;
use warnings;

my $url = "http://172.20.37.115:8080/se/1.0/provision/subscribers/1989
+68";

# use rindex to get the position of the rightmost / character, add 1 
# use substr to extract the remainder of the string after this positio
+n
# perldoc -f rindex
# perldoc -f substr

my $subscriber = substr( $url, ( rindex($url, '/') + 1 ) );

print "$subscriber";
