The I<perlexpr> argument is a Perl expression which is expected to modify the C<$_> string in Perl for at least some of the filenames specified. If a given filename is not modified by the expression, it will not be renamed. If no filenames are given on the command line, filenames will be read via standard input. =head2 Examples (Larry Wall, 1992) For example, to rename all files matching C<*.bak> to strip the extension, you might say file-rename -- 's/\.bak$//' *.bak To translate uppercase names to lower, you'd use file-rename 'y/A-Z/a-z/' ./* Examples rewritten to avoid globs which could inject options. =head2 More examples (2020) You can also use rename to move files between directories, possibly at the same time as making other changes (but see B<--filename>) file-rename 'y/A-Z/a-z/;s/^/my_new_dir\//' ./*.* You can also write the statements separately (see B<-e>/B<-E>) file-rename -E 'y/A-Z/a-z/' -E 's/^/my_new_dir\//' -- *.* =head1 OPTIONS =over 8 =item B<-v>, B<--verbose> Verbose: print names of files successfully renamed. =item B<-0>, B<--null> Use \0 as record separator when reading from STDIN. =item B<-n>, B<--nono> No action: print names of files to be renamed, but don't rename. =item B<-f>, B<--force> Over write: allow existing files to be over-written. =item B<--path>, B<--fullpath> Rename full path: including any directory component. DEFAULT =item B<-d>, B<--filename>, B<--nopath>, B<--nofullpath> Do not rename directory: only rename filename component of path. =item B<-h>, B<--help> Help: print SYNOPSIS and OPTIONS. =item B<-m>, B<--man> Manual: print manual page. =item B<-V>, B<--version> Version: show version number. =item B<-u>, B<--unicode> [I<encoding>] Treat filenames as perl (unicode) strings when running the user-supplied code. Decode/encode filenames using I<encoding>, if present. I<encoding> is optional: if omitted, the next argument should be an option starting with '-', for instance B<-e>. =item B<-e> Expression: code to act on files name. May be repeated to build up code (like C<perl -e>). If no B<-e>, the first argument is used as code. =item B<-E> Statement: code to act on files name, as B<-e> but terminated by ';'. =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. =cut
