NAME
       file-rename - renames multiple files

SYNOPSIS
       file-rename-h|-m|-V ] [ -v ] [ -0 ] [ -n ] [ -f ] [ -d ] [ -u [enc]]
       [ -e|-E perlexpr]*|perlexprfiles ]

DESCRIPTION
       "file-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.

   Examples (Larry Wall,  1992)
       For example, to rename all files matching "*.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.

   More examples (2020)
       You can also use rename to move files between directories, possibly at
       the same time as making other changes (but see --filename)

               file-rename 'y/A-Z/a-z/;s/^/my_new_dir\//' ./*.*

       You can also write the statements separately (see -e/-E)

               file-rename -E 'y/A-Z/a-z/' -E 's/^/my_new_dir\//' -- *.*

OPTIONS
       -v, --verbose
               Verbose: print names of files successfully renamed.

       -0, --null
               Use \0 as record separator when reading from STDIN.

       -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.

       --path, --fullpath
               Rename full path: including any directory component.  DEFAULT

       -d, --filename, --nopath, --nofullpath
               Do not rename directory: only rename filename component of
               path.

       -h, --help
               Help: print SYNOPSIS and OPTIONS.

       -m, --man
               Manual: print manual page.

       -V, --version
               Version: show version number.

       -u, --unicode [encoding]
               Treat filenames as perl (unicode) strings when running the
               user-supplied code.

               Decode/encode filenames using encoding, if present.

               encoding is optional: if omitted, the next argument should be
               an option starting with '-', for instance -e.

       -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.
