upper case or lower case ... if 'tr' was a bash builtin, then that'd work
with some `echo | tr` magic, but it something like
${foo//[[:lower:]]/[[:upper:]]} would be nice

typeset -u (ksh, zsh) supported in bash would be nice...
orchid% typeset -u fuu
So long as it uses declare, not typeset :)
orchid% fuu=bar
orchid% echo $fuu
BAR
I'd prefer variable expansion, perhaps the way Mike suggested, or,
e.g.:
$ foo=bar
$ echo ${foo^} ## Convert first character
Bar
$ echo ${foo^^} ## Convert all characters
BAR
$ echo ${foo^[a-m]} ## Convert first character that matches pattern
Bar
$ echo ${foo^^[a-m]} ## Convert all characters that match pattern
BAr
