[nflug] file name extensions

[Robert Meyer]

Now you gotta remember that some of us have been around since before you were born.  In the days before fire, there was no 'rename' command.  In fact, 'rename' doesn't exist on most Unix systems at all.  It's a linuxism that doesn't translate elsewhere.  Remember, in Unix/Linux, if you can't think of at least three ways to do something, you're not thinking hard enough.

I deliberately submitted my version as a looped shell script 'cuz that was the first thing I thought of.  I thought of the find, second.  I thought of a way to do it with find and perl, too.  In fact, the find/perl solution would be even faster 'cuz you wouldn't have to keep invoking 'mv' for each file.  I remember a way of deleting all files of a certain criteria with something like:
find directory -name '*.bak' -depth -print | perl -ne 'chop;unlink'

Much faster than:
find directory -name '*.bak' -exec /bin/rm '{}' ';'

Cheers!

Bob
