A new command named mv moves files, instead of copying them. The syntax is very straightforward.
/home/larry/foo# mv termcap sells
/home/larry/foo# ls -F
bells sells shells
/home/larry/foo#
Notice how termcap no longer exists, but in its place is the file sells. This can be used to rename files, as we have just done, but also to move a file to a completely new directory.
Note: mv and cp will overwrite
the destination file (if it already exists) without asking you. Be careful
when you move a
file into another directory: there may already be a file with the same
name in that directory, which you'll overwrite!
