NAME

       mvdir - move a directory

SYNOPSIS

       /usr/sbin/mvdir dirname name

DESCRIPTION

       mvdir  moves  directories within a file system. dirname must be a directory. If name does not exist, it will be created as a directory.	If
       name does exist, and is a directory, dirname will be created as name/dirname. dirname and  name may not be on the same path; that  is,  one
       may not be subordinate to the other. For example:

	      example% mvdir x/y x/z

       is legal, but

	      example% mvdir x/y x/y/z

       is not.

OPERANDS

       dirname	       The name of the directory that is to be moved to another directory in the filesystem.

       name	       The  name  of the directory into which dirname is to be moved. If name does not exist, it will be created. It may not be on
		       the same path as dirname.

USAGE

       See largefile(5) for the description of the behavior of mvdir when encountering files greater than or equal to 2 Gbyte ( 2**31 bytes).

EXIT STATUS

       0	Successful operation.

       >0	Operation failed.

ATTRIBUTES

       See attributes(5) for descriptions of the following attributes:
