NAME
       mv  -  move or rename files and directories

SYNOPSIS
       mv file1 file2

       mv file ... directory

DESCRIPTION
       Mv moves (changes the name of) file1 to file2.

       If file2 already exists, it is removed before file1 is moved.  If file2 has a mode which forbids writing, mv prints the mode (see chmod(2))
       and reads the standard input to obtain a line; if the line begins with y, the move takes place; if not, mv exits.

       In the second form, one or more files are moved to the directory with their original file-names.

       Mv refuses to move a file onto itself.

SEE ALSO
       cp(1), chmod(2)

BUGS
       If file1 and file2 lie on different file systems, mv must copy the file and delete the original.  In this case the owner name becomes  that
       of the copying process and any linking relationship with other files is lost.

       Mv should take -f flag, like rm, to suppress the question if the target exists and is not writable.
