=head1 NAME
rename - renames multiple files
=head1 SYNOPSIS
B<rename> S<[ B<-v> ]> S<[ B<-n> ]> S<[ B<-f> ]> I<perlexpr> S<[ I<files> ]>
=head1 DESCRIPTION
C<rename>
renames the filenames supplied according to the rule specified as the
first argument.
The I<perlexpr>
argument is a Perl expression which is expected to modify the C<$_>
string in Perl for at least some of the filenames specified.
If a given filename is not modified by the expression, it will not be
renamed.
If no filenames are given on the command line, filenames will be read
via standard input.
For example, to rename all files matching C<*.bak> to strip the extension,
you might say
rename 's/\.bak$//' *.bak
To translate uppercase names to lower, you'd use
rename 'y/A-Z/a-z/' *
=head1 OPTIONS
=over 8
=item B<-v>, B<--verbose>
Verbose: print names of files successfully renamed.
=item B<-n>, B<--no-act>
No Action: show what files would have been renamed.
=item B<-f>, B<--force>
Force: overwrite existing files.
=back
=head1 ENVIRONMENT
No environment variables are used.
=head1 AUTHOR
Larry Wall
=head1 SEE ALSO
mv(1), perl(1)
=head1 DIAGNOSTICS
If you give an invalid Perl expression you'll get a syntax error.
=head1 BUGS
The original C<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).
