Rename files with spaces instead of underscores

Question

I've got a whole folders of files with names like:

super_awesome___[stuff_here]_-_is_cool.ext
super_duper_coolness___[more_stuff_here]_-_look_at_me_cool.ext

What's the easiest way, in bash, to rename all of them so the underscores become spaces? There are too many files for me to do this manually.

Answer 1

This will replace multiple _ with one for all files named *.ext

for f in *.ext; do mv $f "$(echo $f | sed 's/_\+/ /g')"; done

if you don't want that remove the \+

for f in *.ext; do mv $f "$(echo $f | sed 's/_/ /g')"; done
