NAME
       backup - renames multiple files to have their timestamp in the filename

SYNOPSIS

       backup [ -c ] [ -f ] [ -m ] [ -n ] [ -u ] [ -v ] [ files ]

DESCRIPTION

       "backup" backs up the filenames supplied to copies which include the
       original file's timestamp in their name.

       e.g.

	   backup FILE

       would create FILE.<timestamp>

       If no filenames are given on the command line, filenames will be read
       via standard input (as 'rename' command does).

       If the argument --move (or one of its forms) is given the file will be
       renamed (the default is to create a copy).

	   backup --mv FILE

OPTIONS
       -m, --mv, --move
	       Move: move the file instead of copying it.

       -c, --cp, --copy
	       Copy: (default action so ignored) This is the default because
	       it may be safer to copy a file than go renaming it if it is in
	       use (e.g. a log file) but it will use more disk space!

       -v, --verbose
	       Verbose: print names of files successfully backed up.

       -n, --no-act
	       No Action: show what files would have been backed up.

       -f, --force
	       Force: overwrite existing files.

       -u, --usage, --help
	       Usage: show usage

ENVIRONMENT
       No environment variables are used.

DIAGNOSTICS
       If the new filename already exists or the file already has the times-
       tamp in its name you'll get an error.

TODO
       Perhaps timestamp formatting could be specified on the command line
       (ala date).

       The shell script version has two options, --mvtn and --cptn

BUGS
       The --copy option doesn't work on directories, it creates a file then
       fails.

       The --move option works on a directory if the target doesn't already
       exist.  (move would overwrite an empty target dir or fail on a non-
       empty target dir)

       (the best contact method is via my website, because this email address
       gets much too much spam)


The script is fully documented using pod.
Once installed you should be able to use perldoc backup to get a man page.

The script requires several modules from CPAN. You can get the latest
version via the CPAN multiplexor at http://www.perl.com/CPAN/

	What		Where

	Time::localtime In the Perl distribution
	File::Copy      In the Perl distribution
	Getopt::Long    $CPAN/authors/id/J/JV/JV/Getopt-Long-<version>.tar.gz

I'd be happy to hear of any suggestions for improving this script.
