rename multiple files under linux
 

how can i rename 1k files from xx.jpg in xx.gif from the command line?

I have a custom piece of code that's run from the command line. It's a pain in the ass.

I have to move it to the folder I want to make the changes in and it won't do sub folders. I have to re-code it with any different variable that I want to change and then upload it, then run it from the box.

If you want it I'll try to find it.

Otherwise I have one that runs locally that will search/replace anything in any string on 1,000 files in 2 seconds.

LMK and I will try to help you.
.

bash$ man find
Take a look at -exec or create a shell script

for i in *; do echo mv $i "`echo $i | tr .jpg .gif `"; done | bash
