The what?

Dead simple.
How do I rename

hello_kitty2.png
hello_kitty3.png

to

byebye_kitty2.png
byebye_kitty3.png

I think it’s simple, but it’s hard to Google for this kind of thing unless you already know.

The how…..!

You can do this with a simple one-liner with bash

for file in $(ls hello_ki*); do mv "$file" "${file/hello/byebye}"; done
