Rename Multiple Files in Bash Using Regular Expressions

Published in: Bash

This small, bash script will loop though the specified files and rename them according to a sed regular expression. In this example, I'm renaming a bunch of .avi movie files.

Expand | Embed | Plain Text

for i in *.avi
do
j=`echo $i | sed 's/find/replace/g'`
mv "$i" "$j"
done
 
Can also be written on a single line as
 
for i in *.avi; do j=`echo $i | sed 's/find/replace/g'`; mv "$i" "$j"; done

prename is much simpler, and it is in the perl standard distributio that is installed in almost all unix systems. to use it: prename 's/find/replace/ files
