NAME
mv - move or rename a file
SYNOPSIS
mv name1 name2
DESCRIPTION
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
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.
BUGS
It should take a -f flag, like rm, to suppress the question
if the target exists and is not writable.
