You rename a directory by moving it to a different name. Use the mv command to rename directories:
$ pwd /home/user2/veggies $ ls broccoli $ mv broccoli carrots $ ls carrots |
You can also use mv to move a directory to a location within another directory:
$ pwd /home/user2/veggies $ ls carrots $ mv carrots ../veggies2 $ ls ../veggies2 carrots |
In this example, the directory carrots is moved from veggies to veggies2 with the mv command.
