FWIW, I have been using a script based on the "sed" command.
I got the script from some book or ftp site, unfortunately
not recorded in the header, and it runs on Cygwin with my
AT&T Korn shell -- not sure why, maybe because of the syntax
for declaring functions?

The only problem I have had with this script is that if a
target filename already exists, that file will be overwritten.

#	ls o*.c | rename 's/^o/old\//'

function rename_1 {
	typeset gname=`print -R "$1" | sed "$subst"`
	if	[ "$1" != "$gname" ]
	then	mv "$1" "$gname"
	fi
}

case $# in
0)	print >&2 "Usage: $0 'sed command' [file ...]"
	exit 2
	;;
1)	subst="$1"
	while read fname; do rename_1 "$fname"; done
	;;
*)	subst="$1"; shift
	for fname; do rename_1 "$fname"; done
	;;
