Re: One-liner for Matching a Regex in a Directory of Files

a four letter word starting with M

In that case, you should also be using the carat to tell your regex that the letter "M" is found just after the beginning of the filename.

m/^M[A-Z]{3}/

So you get:

perl -le'foreach ( <*.txt> ) { print if /^M[A-Z]{3}/ }'

Sorry, I didn't mean to imply that that M was at the beginning of the file. Each text file is a separate essay and the acronym was just a word in the body of the file. I combined ideas from both tips to come up with the following (semi-Perl) solution. Thanks for your help Paladin and allolex. `for %a in (*.txt) do @perl -ne "if (m/ (M[A-Z]{3}) /) { print qq($1\n); }"` `%a`	[reply] [d/l] [select]
