How to remove a reoccuring word/character and what comes after, from the filenames of multiple files?

Question

I have several folders of video files where, due to the download manager I use, they are all named in the following format "FILENAME.mp4; filename= FILENAME.mp4" All I've been trying to do is to remove everything after (and including) ".mp4; filename". However, I haven't found a way to do this.

I have tried some free software (such as Renamer, Namechanger, Name Munger for Mac, Transnomino) but I failed to do what I need to.

I'm working on Mac OSX 10.13.6.

Any help with this issue would be appreciated.

You can achieve it using Terminal. Go to the folder where you want to rename files using this cd command, for example:

cd ~/Documents/Videos

And run this command to rename all files recursively:

find . -iname "*.mp4;*" | sed -E 's/(\.[^\.]*)(\.mp4)(.*)/mv "\1\2\3" "\1\2"/' | sh

This command will keep only FILENAME.mp4 part from FILENAME.mp4; filename= FILENAME.mp4 file name
