Perl Module Monday: File::Tail

December 7th, 2009 Posted in CPAN, Perl

Today, a short one as I’m short on time. But I wasn’t able to do a PMM last week, and I’d hate to skip it two weeks in a row, so…

Say hello to File::Tail. A simple concept, but a very, very useful one.  Ever run the *NIX “tail -f <file>” command? Yeah, it’s pretty much just like that. Only in Perl, so it’s actually more flexible. Much more.

You can use it in a very simple manner, to read from files that are continuously updating. You can control how often and to what degree it adjusts the wait-interval it uses when polling the underlying file to check for changes. You can also tie a file-handle to it. You can do things like select-polling across several such handles or objects, to read in a non-blocking way from multiple tail’d files at once. It even comes bundled with two sample scripts showing it in action.

Check it out!
