How do I Remove Specific Characters From File Names Using BASH

Question

I have a lot of files that have a shared pattern in their name that I would like to remove. For example I have the files, "a_file000.tga" and "another_file000.tga". I would like to do an operation on those files that would remove the pattern "000" from their names resulting in the new names, "a_file.tga" and "another_file.tga".

Answer 1

Bash can do sed-like substitutions:

for file in *; do mv "${file}" "${file/000/}"; done

Answer 2

Try this (this works in plain old Bourne sh as well):

for i in *000.tga
do
    mv $i `echo $i | sed 's/000//'`
done

Answer 3

A non-bash solution, since I know two speedy posters have already covered that:

There's an excellent short perl program called rename which is installed by default on some systems (others have a less useful rename program). It lets you use perl regex for your renaming, e.g:

rename 's/000//' *000*.tga

Answer 4

#!/bin/bash
ls | while read name; do
  echo mv $name ${name/$1//}
done
