rename - renames multiple files


rename [ -h|-m|-V ] [ -v ] [ -n ] [ -f ] [ -e|-E perlexpr]*|perlexpr [ files ]


"rename" renames the filenames supplied according to the rule specified as the first
argument. The perlexpr argument is a Perl expression which is expected to modify the $_
string in Perl for at least some of the filenames specified. If a given filename is not
modified by the expression, it will not be renamed. If no filenames are given on the
command line, filenames will be read via standard input.

For example, to rename all files matching "*.bak" to strip the extension, you might say

rename 's/\e.bak$//' *.bak

To translate uppercase names to lower, you'd use

rename 'y/A-Z/a-z/' *


-v, -verbose
Verbose: print names of files successfully renamed.

-n, -nono
No action: print names of files to be renamed, but don't rename.

-f, -force
Over write: allow existing files to be over-written.

-h, -help

-m, -man

-e Expression: code to act on files name.

May be repeated to build up code (like "perl -e"). If no -e, the first argument
is used as code.
