I'd use Perl for this, but you could also use PHP or Ruby or (insert
Turing-complete language here). The main disadvantage of shell is that its
syntax isn't as easy for doing programming things as some other languages,
it's not as easy to do math or complex data structures in shell, and shell can
require spawning many other processes.

Perl is a great sysadmin language; it's like a Swiss Army Chainsaw that
contains an infinite length of duct tape :-) The key to Perl is the same as
the key to many other languages: Don't get too clever, write comments that
document what's going on, and keep the comments in sync with the code.
Otherwise you'll end up swearing at yourself at 0-dark-thirty while people ask
you when the server's going to be up.
