How to do a mass rename?

Question

I need to rename files names like this

transform.php?dappName=Test&transformer=YAML&v_id=XXXXX

to just this

XXXXX.txt

How can I do it?

I understand that i need more than one mv command because they are at least 25000 files.

Answer 1

Try the rename command

Or you could pipe the results of an ls into a perl regex.

Answer 2

find -name '*v_id=*' | perl -lne'rename($_, qq($1.txt)) if /v_id=(\S+)/'

Answer 3

This should also work:

prfx='transform.php?dappName=Test&transformer=YAML&v_id='

ls $prfx* | sed s/$prfx// | xargs -Ipsx mv "$prfx"psx psx

Answer 4

this renamer command would do it:

$ renamer --regex --find 'transform.php?dappName=Test&transformer=YAML&v_id=(\w+)' --replace '$1.txt' *

Answer 5

vimv lets you rename multiple files using Vim's text editing capabilities.

Entering vimv opens a Vim window which lists down all files and you can do pattern matching, visual select, etc to edit the names. After you exit Vim, the files will be renamed.
