The nessasary prompt jibberish to rename JPG files to jpg files.
for f in *.JPG; do mv $f `echo $f | tr '[:upper:]' '[:lower:]'`; done

And that is more or less the same as the command "rename .JPG .jpg *".

–

Even more Gibberish for making photoalbums.
for f in *.jpg; do cp ../picsdesc.txt `echo $f | cut -b1-8`'.txt'; done

 

 

find . -name \*.oio -exec mv {} ../oldcrap/ \;
