Yes, I see that, but the only tricky thing about the perl code above is 
this regular expression...

(^.*)/[^/]+\.m

...and you can use regexps like that one in a few scripting languages and 
with egrep and other tools.  I definitely highly recommend learning the 
regexp tricks because you can do some really great things easily once you 
learn a few things.

Regarding perl - I think it is becoming a core unix tool.  We used to use 
sed and awk for more of the things that perl is now taking over.  For 
programming, there will always be arguments about what is best, but for 
simple one-liners, I think perl has won that battle, or it has at least 
won me over.
