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).
