Re: regex question

Are you sure you're testing correctly?

$ perl -le'$_="directoryy"; print if /(directory|file|age|action)/'
directoryy
$ perl -le'$_="directorys"; print if /(directory|file|age|action)/'
directorys

Apparently the problem is somewhere else..

Thanks for pointing it out. I did mis-state my problem. I only want to match if $_ is an exact match for the alternate. I only want to match on 'directory', not 'directorys' or 'directoryy' or 'cheeze whiz'.	[reply]

Use `\b` to assert a word boundary then. `my $word = qr/\b(directory\|file\|age\|action)\b/;` Or `^` and `$` to assert string start/end (respectively). `my $word = qr/^(directory\|file\|age\|action)$/;` Or any combination of the two that you like.
