man prename (Commandes) - renames multiple files

NAME

rename - renames multiple files

SYNOPSIS

rename [ -v ] [ -n ] [ -f ] perlexpr [ files ]

DESCRIPTION

CWrename 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 CW$_ 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 CW*.bak to strip the extension, you might say 

        rename 's/\.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, --no-act
No Action: show what files would have been renamed.
-f, --force
Force: overwrite existing files.

ENVIRONMENT

No environment variables are used.

DIAGNOSTICS

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

BUGS

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