                     53: .SH DESCRIPTION
                     54: In the first form of each command,
                     55: .I file2
                     56: is any name except an existing directory.
                     57: In the second form the command
                     58: copies, moves, or links one or more
                     59: .I files
                     60: into a
                     61: .I directory
                     62: under their original filenames, as if by a sequence of 
                     63: commands in the first form.
                     64: Thus
                     65: .L "mv f1 f2 dir
                     66: is equivalent to
                     67: .LR "mv f1 dir/f1; mv f2 dir/f2" .
                     68: .PP
                     69: .I Cp
                     70: copies the contents of plain
                     71: .I file1
                     72: to
                     73: .IR file2 .
                     74: The mode and owner of  
                     75: .I file2
                     76: are preserved if it already
                     77: exists; the mode of
                     78: .I file1
                     79: is used otherwise.
                     80: .PP
                     81: .I Mv
                     82: moves
                     83: .I file1
                     84: to
                     85: .IR file2 .
                     86: If the two files are in the same file system, the name
                     87: .I file1
                     88: is simply changed to
                     89: .IR file2 ;
                     90: if they are in different file systems,
                     91: .I file1
                     92: is copied and then removed.
                     93: If
                     94: .I file2
                     95: already exists, it is removed before
                     96: .I file1
                     97: is moved.
                     98: In this case the mode of
                     99: .I file2
                    100: is reported if it
                    101: is not writable and the standard input is a terminal.
                    102: Respond
                    103: .L y 
                    104: (and newline) to permit removal.
                    105: .PP
                    106: .I Ln
                    107: links plain
                    108: .I file1
                    109: and
                    110: .IR file2 .
                    111: .I File2
                    112: becomes an alternate name for, and is otherwise
                    113: identical to,
                    114: .I file1.
                    115: .I File2
                    116: must be in the same file system as
                    117: .I file1
                    118: and must not already exist.

                    121: copies plain files like
                    122: .I cp,
                    123: but copies directories and their contents recursively.
                    124: It attempts to duplicate linkage and dates.
                    125: When run by the super-user, it preserves ownership
                    126: and copies device files as device files.
                    127: .PP
