I found rename on Ubuntu 10 doesn't support regex unfortunately. I need to rename files containing _thumb to _t leaving the rest as is. Example: rename SLN0097H_thumb@2x~ipad.JPG to SLN0097H_t@2x~ipad.JPG. Hopefully it's possible to do without writing bash script loop.

Not sure why you want to avoid a bash loop, but here's one:

for i in *_thumb*; do mv "$i" "${i/_thumb/_t}"; done

I have an old script you can try - works like

splat "wid" "wod" "wid*" [do]

wid_popup.c -> wod_popup.c

wid_popup.h -> wod_popup.h

wid_splash.c -> wod_splash.c

wid_splash.h -> wod_splash.h

just add "do" to the args if the rename makes sense. There are probably shorter ways to do this, but hey, it works for me 8)

#!/bin/sh
#
# splat-name "pattern" "replacement" "files" [do]
#
# Searches for <pattern> in the matching filenames and uses sed to replace
# with <replacement> in the same filename. i.e. it renames parts of files.
#
# Nothing is done unless [do] is added, so you can test out that it works.
#
if test $# -lt 3
then
    echo
    echo "Performs recursive file name changes"
    echo
    echo "usage: splat-name \"<pattern>\" \"<replacement>\" \"<files>\" [do]"
    echo
    echo "e.g:"
    echo "  splat \"rm\" \"remove\" \"Makefile\""
    echo "Then when sure it works:"
    echo "  splat \"rm\" \"remove\" \"Makefile\" do"
    echo
    echo "splat $*"
    exit
fi
