Replacing both spaces and " - " in filenames and directorys

Question

I have been reading this this discussion and this find . -depth -name '* *' \ | while IFS= read -r f ; do mv -i "$f" "$(dirname "$f")/$(basename "$f"|tr ' ' _)" ; done
helps me deleting spaces in files and directories.
Beat Boy becomes Beat_Boy. This is ok.
What I don't get right is how to deal with this:
Beat Boy - Best of becomes Beat_Boy_-_Best_of while I want it to be Beat_Boy-Best_of.
I would appreciate any hint which way to go...

Regards

Answer 1

You can add sed to substitute "_-_" with "-"

f="Beat Boy - Best of"

echo $f | tr ' ' _ | sed 's/_-_/-/g'
#Beat_Boy-Best_of

In your case, you would want:

find . -depth -name '* *' | 
    while IFS= read -r f ; do 
        mv -i "$f" "$(dirname "$f")/$(basename "$f" |
            tr ' ' _ |
            sed 's/_-_/-/g')" ; 
    done

Edit

You can also replace tr ' ' _ | sed 's/_-_/-/g' with sed 's/ /_/g ; s/_-_/-/g'.
