CPNEW - Copy new files to backup (Rainbow or IBM PC)

                cpnew [-abcfiprv] source,source,... target


        Sources are directory names or file specifications; source
        specifications may contain a drive and/or a directory path and
        wildcard characters.

        The target is either a directory name or a disk drive letter
        followed by a colon.  For each file matched by the first
        argument, CPNEW looks in the directory or drive specified by
        the second argument for a file of the same name.  If no such
        file exists, or if it exists but has an older date than the
        source file, the source file is copied to the target location.

        If the target is "2:", drives A and B are treated as one big
        drive; matching files are searched for first on A, then on B.
        when a new file is created, CPNEW first tries to put it on A; if
        the file won't fit on A it is put on B.

        If a source filespec contains a drive and/or directory, these
        are passed along to the subsequent source filespecs until
        reassigned; thus

                cpnew \src\*.c,*.obj,\exe\*.* b:

        is the same as

                cpnew \src\*.c,\src\*.obj,\exe\*.* b:

        and

                cpnew b:bob,carol,\tmp\ted,alice \bed

        is shorthand for

                cpnew b:bob,b:carol,b:\tmp\ted,b:\tmp\alice \bed

        If there is not enough room on the target disk for the copy,
        the program pauses while the user changes disks; the file
        checking then continues.

        Options:

        -a (attributes)

        Causes the target file to inherit the attributes (read-only,
        hidden, etc.) of the source file.  Normally the target file is
        created read/write, non-hidden, non-system, with the archive bit
        clear (e.g. not backed up).

        -b (incremental backup)

        Implies -cfp (see below).  If the target is omitted, 2: is
        assumed.

        -c (changed)

        Consider only those files whose archive bit is set (i.e.  that
        have been changed since the last real BACKUP).

        -f (flag)

        Flag the source file, i.e.  turn off the archive bit.

        -i (input)

        The list of files to copy is taken from the standard input rather
        than the command line.  Thus with -i the format of cp is

                cpnew -i [-cfprv] target

        This is useful when using cp as a filter. e.g.

                ls -fm | cp -i a:

        copies files in order from smallest to largest.  This insures that
        the most files will be copied to a: before it fills.

        -p (path)

        The target must be a drive letter followed by a colon.  If a
        directory (path) specification is present for a source file, it
        will be copied to a path of that name on the target drive.
        Directories are created on the target drive as needed.

        The command

            cpnew -p \exe\*.*,\src\*.* a:

        will copy files to directories a:\exe and a:\src

            ls -rdf \ | cpnew -ip B:

        will backup up all of the current drive onto floppies on B

        -r (replace)

        Replace only (don't create), i.e.  don't copy unless an older
        version of the file already exists on the target.

        -v (verify)

        Causes user confirmation to be requested before copying.  At each
        file prompt the user answers either Y (do the copy), ! (do the
        copy and don't ask for confirmation on future files), or N (don't
        copy this file).  Any other answer is the same as N.

        Thanks to Glen C. Siegel, whose program KOPYNEW was the
        inspiration for CPNEW.
