- # What's the point in removing the extension ? anyway, no idea if this works, so first of all try this:
- # find . -type f -name '*.mp3' | while IFS= read -r line; do printf 'mv -- %s %s\n' "$line" "${line%.mp3}"; done
- # If it seems fine to you,
- # find . -type f -name '*.mp3' | while IFS= read -r line; do mv -- "$line" "${line%.mp3}"; done
- # >>86204496 (You)
- # Assigning 2 ($2) does not work, unless it's zsh ... in which case, you might want to use zmv:
- # autoload -Uz zmv
- # zmv -n '**/*.mp3' '${f%.mp3}'
- # Remove the -n option if the commands seem fine to you. for the more readable command see >>86204501
