Same here. On my linux system (gentoo) the command takes the form: rename 'from' 'to'

Hey, this striped off the end of my post! It should have been: rename 'from' 'to' FILE_PATTERN

Actually this is what I use: for x in *; do mv "$x" "`echo $x | tr [A-Z] [a-z]`"; done

Only convert files, not directories: find ./ -type f -exec rename 'y/A-Z/a-z/' {} \;

Use something like for i in *; do mv "$i" tempfile; mv tempfile "$(echo $i | tr '[A-Z]' '[a-z]')"; done if you mount vfat partition in linux.
