rename

RENAME(1)							   User Commands							 RENAME(1)

NAME

       rename - rename files

SYNOPSIS

       rename [options] expression replacement file...

DESCRIPTION

       rename will rename the specified files by replacing the first occurrence of expression in their name by replacement.

OPTIONS

       -v, --verbose
	      Give visual feedback which files where renamed, if any.

       -V, --version
	      Display version information and exit.

       -s, --symlink
	      Peform rename on symlink target

       -h, --help
	      Display help text and exit.

EXAMPLES

       Given the files foo1, ..., foo9, foo10, ..., foo278, the commands

	      rename foo foo0 foo?
	      rename foo foo0 foo??

       will turn them into foo001, ..., foo009, foo010, ..., foo278.  And

	      rename .htm .html *.htm

       will fix the extension of your html files.

WARNING

       The  renaming  has  no safeguards.  If the user has permission to rewrite file names, the command will perform the action without any ques-
       tions.  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.

SEE ALSO

       mmv(1), mv(1)

AVAILABILITY

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