Whoah there Tex... Multi-file search-n-replace is *really* simple from
the command line:
$ for file in *.txt ; do ( sed "s/Text To Replace/Text To Replace
With/g" < $i > tmp ; mv tmp $i ) ; done
Which really should be a LOT faster than that big Perl script (not that
Perl isn't cool...) because you won't have to fiddle around with the
Perl script first!
