One-liner for Matching a Regex in a Directory of Filesby svsingh (Priest)
|on Jan 10, 2004 at 19:58 UTC||Need Help??|
svsingh has asked for the
wisdom of the Perl Monks concerning the following question:
I have a directory with about thirty text files. I was trying to find an acronym in the directory, but I didn't really remember what it was (other than it was a four letter word starting with M).
I tried a few one-liners, but none of them worked. Since I was just trying to find something really quickly, I decided to punt and just write a script to do what I wanted.
Now I'm trying to learn more about one-liners (I don't have any experience with them) just so I can handle this situation a bit better next time it comes up.
I should also note that I'm doing this from a Windows command prompt.
Here are some of the one-liners that I tried (in a for loop, single file example shown here):
And finally, here's the subroutine that actally did what I wanted:
Is there a way to do something like this as a one-liner? If so, then can I incorporate the glob into the one-liner? Thanks for your help.
