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

Answer 1

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

Both arguments are wrapped in quotes to support spaces in the filenames.

Answer 2

Bash can do sed-like substitutions:

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

Use rename, maybe you need to install it on linux, Its python script

rename (option) 's/oldname/newname' ...

so you can use it like

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

that means we are instructing to replace all files with .tga extension in that folder to replace 000 with empty space. Hope that works
