     mv  -  move or rename a file

     mv name1 name2

     Mv changes the name of name1 to name2.  If name2 is a direc-
     tory, name1 is moved to that  directory  with  its  original
     file-name.   Directories  may  only be moved within the same
     parent directory (just renamed).

     If name2 already exists, it is removed before name1  is  re-
     named.  If name2 has a mode which forbids writing, mv prints
     the mode and reads the standard input to obtain a  line;  if
     the line begins with y, the move takes place; if not, mv ex-

     If name2 would lie on a different file  system,  so  that  a
     simple  rename is impossible, mv copies the file and deletes
     the original.

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