82 permission to rewrite file names, the command will perform the action without
83 any questions. For example, the result can be quite drastic when the command
84 is run as root in the /lib directory. Always make a backup before running the
85 command, unless you truly know what you are doing.
87 As most standard utilities rename can be used with a terminal device (tty in
88 short) in canonical mode, where the line is buffered by the tty and you press
89 ENTER to validate the user input. If you put your tty in cbreak mode however,
90 rename requires only a single key press to answer the prompt. To set cbreak
91 mode, run for example:
95 sh -c 'stty -icanon min 1; "$0" "$@"; stty icanon' rename -i from to files
104 all requested rename operations were successful
107 all rename operations failed
110 some rename operations failed
116 unanticipated error occurred
122 The rename command is part of the util-linux package and is available from
