Question

Say I have folders:

img1/
img2/

How do I delete those folders using regex from Linux terminal, that matches everything starts with img?

Answer 1

Use find to filter directories

$ find . -type d -name "img*" -exec rm -rf {} \;

As it was mentioned in a comments this is using shell globs not regexs. If you want regex

$ find . -type d -regex "\./img.*" -exec rm -rf {} \;
