How to rename several files using a mask in the console?

Question

bash

It is necessary to recursively rename files according to the mask *-en.srt -> *.srt (spaces are allowed in the name)
It's easy with one file if I set the name: I can't understand all at once. I think something should be written with a cycle, but there is not enough knowledge in bash.
mv "first subtitle-en.srt" "first subtitle.srt"

Answer 1

rename "-en.srt" ".srt" *-en.srt

Answer 2

rename 's/-en.srt$/\.srt/' *-en.srt
