Replace spaces in filenames with underscores

for f in *;do mv "$f" "${f// /_}";done
I realize there's a few of these out there, but none exactly in this form, which seems the cleanest to me

What Others Think

Beware of this. If you have this 2 files i.e. important_file important file Your loop will overwrite important_file I suggest to verify first if the file exists. for f in *; do file=$(echo $f | tr A-Z a-z | tr ' ' _) [ ! -f $file ] && mv "$f" $file done

I like it :) We don't have rename by default on OS X bash shell. How would I do this if I only wanted to do one file, i.e. without the for loop part?
