     mv  -  move or rename a file


     mv name1 name2


     Mv changes the name of  name1  to  name2.   If  name2  is  a

     directory,  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

     renamed.   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 exits.

     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.
