Beginners Level Course: Useful Commands - The 'mkdir' command
'mkdir' is the command for making directories. 'mkdir' may be familiar to MS-DOS users out there. As you have noticed, the people who wrote these programs tried to give them names that described what they do more or less, not as long as 'makemeadirectoryplease' and not too cryptic like 'xr77b'.
Using the 'mkdir' command To create the directory 'my_friends' that we talked about in the last lesson, you would type:
There are no whistles or buzzers. If you'd like some sort of acknowledgment, you could type
mkdir --verbose my_friends
and it will tell you that you created the directory. If you type ls -l You'll see it there along with information about it. Now you know how to use 'mkdir'. You can even use it to create a directory called 'my_enemies' if you're into that sort of thing.
The 'rmdir' command 'rmdir' is the opposite of 'mkdir'- it gets rid of directories. It should be pointed out that in order to use it, the directory has to be empty. If you copied or moved anything to 'my_friends' and you typed
Linux would politely tell you that you can't do that.
So, you have to use your 'rm' command on the files first to remove them or use 'mv' to get them into another directory. Then you're free to use 'rmdir' So, next we'll deal with the 'rm' command.
