According to everything I have read on PM, the use of rindex() and substr() is a poor way to do this task.
What the...? Can anyone second that

To a certain degree I can second that. Using rindex and index can cause issues. Consider if you have directories with dots in em? Consider if you have multiple extensions, eg File.pl.bak. And for using rindex and index for other aspects of path parsing is also bad especially when you consider the the various path delimiters, and portability issues.

Actually it was the use of rindex that caused a script here to behave very strangely just the other day.

BTW, you and snafu might like to have a look at one of my earlier posts (and the thread its in) for some interesting discussion about parsing filenames/urls with a regex.
