And here is another nice little script for a problem I have. I use awesome as
window manager, and in my rc.lua file i've setup some nice tweaks so that my
wallpaper changes every 5 minutes to a new one randomly chosen from
/usr/share/wallpapers/.

(done by: awsetbg -r '/usr/share/wallpapers' in a crontab.)
I have a lot of wallpapers, over 1500. awsetbg/feh has some problems with
filenames and so once in a while I got an error message from feh,
This scripts renames all the jpg files in a folder to a number. Instead of
having Beach.jpg, Clouds.jpg and Tux.jpg you will have 1.jpg, 2.jpg
and 3.jpg.
Script:
#!/bin/bash
RAYMIIWALL=1
#convert everything to lowercase - you need the rename command.
rename 'y/A-Z/a-z/' *
for i in {*.jpg,*.jpeg};
do mv -f -v "$i" "$RAYMIIWALL.jpg";
let "RAYMIIWALL += 1"
done
exit 0
If you get an error like:
mv: cannot stat '*.jpeg': No such file or directory then it means that there
are no jpeg files to rename.
