(I keep forgetting how to do this!)

* returns all files in a directory. It can also be used as a general wildcard:

• *.jpg will return only JPG filenames
• something* will return only filenames that start with something

for f in *; do mv $f $(echo $f | sed SED_SCRIPT); done

Place any sed string in place of SED_SCRIPT. Done!

Need more sed?
