RENAME(1p)                     User Contributed Perl Documentation                     RENAME(1p)

NAME
       rename - renames multiple files

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

DESCRIPTION
       "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/' *

OPTIONS
       -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
               Help: print SYNOPSIS and OPTIONS.

       -m, -man
               Manual: print manual page.

       -V, -version
               Version: show version number.

       -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.

       -E      Statement: code to act on files name, as -e but terminated by ';'.

ENVIRONMENT
       No environment variables are used.

DIAGNOSTICS
       If you give an invalid Perl expression you'll get a syntax error.

BUGS
       The original "rename" did not check for the existence of target filenames, so had to be
       used with care.  I hope I've fixed that (Robin Barker).
