Directory management

As you probably know, a directory is a file that stores other files. In Raspbian (and Linux in general), all files are stored under the root directory (represented by the slash (/) character) in a tree-like structure. In this section, we will describe some basic commands used to manage directories in Raspbian.

Create a directory

The mkdir command is used to create a directory:

mkdir command

Move a directory

To move a directory, the mv command is used. Two parameters need be specified: the first paramter is the directory you would like to move and the second parameter is the location where you would like to move the directory to. For example, if we want to move the directory named new-directory located at /home/pi/ to /tmp/, we need to enter the following command:

mv command

Delete a directory

The rmdir command is used to delete a directory. For example, to delete the directory new-directory located at /tmp/, the following command needs to be used:

rmdir command

If you get the rmdir: failed to remove ‘/tmp/new-directory/ ‘: Directory not empty error, it means that your directory contain files. To remove the directory along with the content of the directory, use the rm command with the -r option:

rm r command

Copy a directory

To copy a directory, use the cp command with the -r flag and two parameters: the source directory you would like to copy and the destination. For example, to copy the /home/pi/new-directory to the /tmp/ directory, use the following command:

cp r command

There is a difference between the cp and mv command. With cp, the file is being duplicated, and the original file is retained in the original location. With mv, the file is being moved from one location to another, and the original file will not be retained in the original directory anymore.
