Re: Regex problem

Thank your for your early responses, but my concern here is if the array @index_corr_file has something like qw(1 11 23 45 22) and suppose the $index = 2, then the grep function will be true and the if condition will pass. But i want $index to match to only 2 not otherwise. Is there any way to minimize the code. Sid

If you want to test for equality, then by all means! `if ( grep { $index == $_ } @index_corr_file ) { # whatever }` [download] -- edan	[reply] [d/l]

This will help you, ~~grep(/^$index$/, @index_corr)~~ update: As edan said, it will help you `grep{$index==$_} @index_corr` Prasad	[reply] [d/l]

I downvoted your post, and I'll tell you why - IT'S WRONG! Why would you give somebody a regex solution when they clearly need to test for equality!? What if `$index` contained regex metacharacters? In short, I think it's a bad habit to use an anchored regex when you mean "equals". `perl` provides us with `==` and `eq` for a reason. Use them. -- edan	[reply]
