I’ve created a script which let’s a client upload an mp3 audio file however it’s being save in a format like 2030131_9ec3-4ad1-84ae-c98b68390322.mp3. The files reside in a folder and sub-folder format that resembles a date. ./2019/05/31/639486572_016b0f3d-9ec3-4ad1-84ae-c98b68390322.mp3.
The goal is to remove everything before and including the _. Which I’m able to do with rename -v 's/$\.+_//'
But when I try to couple this with find it seems to rename all the files found in the subfolder correctly but places\moves them to the root of the folder I’m working out of so in this case ./2019
The command im running is find -type f -name "*_*" | rename -v 's/$\.+_//'
How can I ensure the files location doesn’t change ?

Hi @Remdore,
I think you need to better understand Regex and how it works.
$\ will be undefined and will do nothing in your regular expression.
.+_ will match everything from the beginning of a string to the last _ character, including the path information. You’ll want to use a more restrictive expression that won’t capture the whole path.
There are a few ways you can do it:
s![^/]+_!! greedy match of consecutive non-/ chars
s!(.+/)?.+_!$1! capture path and include it in the replacement
There is also a solution that would use a negative look-behind assertion, when you are ready to dive in the deep water.
