Question:
What have your tried so far?

How can we work with what you want, if we do not know the information we are looking for?

Thanks

You can't search a regexp, the question makes no sense. You can search a file or a database, but you can't search a regexp.

I have tried to serch each and every line in the file using

open FH,"log";
for $line(<FH>){
if( $line =~ m/regexp/ )
{
}
}

but i dont want to look each and every line in the file

Thanks

If you don't try and match against every line, how are you going to have a proper search? Inside of the if statement, if you don't do anything, like print the line or the line number, then you will never know that there was a match.

maybe this is what you want, hard to say because I guess you think we can read your mind and understand your vague question:

open FH,"log";
while (my $line = <FH>){
   if( $line =~ m/regexp/ ) {
      "Found regexp in $line\n";
      last; $stops searching after first match
   }  
}
close FH;

If thats not what you are trying to do then please explain yourself properly so other people can understand what your requirements are.

I know in the quick making of that script you may of made a mistake or typo at

$stops Searching

Yes thanks, should have been "#stops searching" instead of "$stops Searching".
