🚀 go-pugleaf

This is from Dan LaLiberte of the University of Illinois at
Urbana-Champaign.  I've used it for years.  The conversion to
Bourne-shell syntax should be obvious.  Usage is like
	rename 's/\.xyz$/abc/' *.xyz

# Here is my rename script.

# rename files with a sed command.  File names may have spaces in them.

if ($#argv < 2) then
	echo "Usage: rename sed-command file ..."
	exit (1)
endif
set command = "$1"
shift
set noglob
while ($#argv > 0)
	set name = ($argv[1])
	shift
	set newname = `echo "$name" | sed -e "$command"`
	if ($status != 0) exit 1
	echo "mv -i $name $newname"
	mv -i "$name" "$newname"
end
exit 0
