Actually, you'd use Perl ;)

For example, if I were to have a sex change, I might

	perl -p -i'.orig' -e 's/(Alex)/$1andria/g;' *

Not only does this change my name everywhere, it even backs up my files
in case I make a mistake.

man perlrun is fairly good, and not as difficult as some man pages. man
perlre too. Otherwise, there's the O'Reilly books, perlmonks.org,
useperl.org, etc. etc.O'Reilly Perl cd bookshelf can be installed on
your machine, and the websites are even available on Windows :)

Cheers,

Alex.
