WARNINGThe renaming has no safeguards by default or without any one of the options --no-overwrite, --interactive or --no-act. If the user has permission to rewrite file names, the command will perform the action without any questions. For example, the result can be quite drastic when the command is run as root in the /lib directory. Always make a backup before running the command, unless you truly know what you are doing.
INTERACTIVE MODEAs most standard utilities rename can be used with a terminal device (tty in short) in canonical mode, where the line is buffered by the tty and you press ENTER to validate the user input. If you put your tty in cbreak mode however, rename requires only a single key press to answer the prompt. To set cbreak mode, run for example:
sh -c 'stty -icanon min 1; "$0" "$@"; stty icanon' rename -i from to files
- all requested rename operations were successful
- all rename operations failed
- some rename operations failed

AVAILABILITYThe rename command is part of the util-linux package and is available from https://www.kernel.org/pub/linux/utils/util-linux/.
