NAME

rename - renames multiple files  

SYNOPSIS

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

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).
