What Others Think

For the love of $diety, don't do this! This will break if any of the filenames have spaces (at the very least). * loop with `for fname in *` * quote variables, especially when they're filename or used as arguments Also, consider using `mv -i` to confirm overwrites in case the directory has files with almost-duplicate names. for FName in * ; do LowerFName=$(echo "$FName" | tr '[:upper:]' '[:lower:]'); mv -iv "$FName" "$LowerFName" ; done

here is some simple tricks without using `tr` `name='name.extension'; echo "${name^}"; echo "${name^^}"; name='NAME.EXTENSION'; echo ${name,}; echo ${name,,};` and output ``` Name.extension NAME.EXTENSION nAME.EXTENSION name.extension ```
