How to grep the string in perl.

Variable sessionWeb contains a web page html code. I want to grep "active Sessions" from this and want to print as below. For example the line in the web page will be

"2 active Sessions, 0 passivated Sessions (more stats...)"

Expected Output:

2 active Sessions.

I have tried the following code but it is not working ?

 $sessionStr="active Sessions";
     $sessionCount =~ grep( /$sessionStr/,$sessionWeb);

While we have traditionally welcomed questions about sysadmin-level scripting, this sort of question is really a better fit for Stack Overflow or Unix & Linux –  voretaq7 Apr 27 '12 at 6:54

This should to the trick:

if ($sessionWeb =~ /(\d+ active Sessions)/) {
  print $1."\n";
}

It is printing the entire html page –  Arun Apr 27 '12 at 6:45
    
The above code extracts only the requested part. There must be a bug in your code. –  Oliver Apr 27 '12 at 6:49
