16.2 Management of Directory and File
16.2.1 Creating Directory
In the Raspberry Pi system, all data is stored in a directory, so the directory must be created before saving the data.
16.2.1.1 "mkdir" Command – Create Directory
To create a directory in Shell, you can use the following command.
[Command Format]
| mkdir [OPTION] <directory> |
[Command Overview]
■ This creates a directory at the specified location.
■ User privilege -- Normal user.
[Detail Description]
When specifying a directory, you can specify the path where the directory will be created. If you do not specify a path, it will work in the current directory.
[Main Option]
| --help | display this help and exit |
[Used Example]
If you create a directory as follows and check it, you can see that the directory is created.
| pi@raspberrypi ~ $ mkdir ./testdata/TestFolder01 |
| pi@raspberrypi ~ $ ls ./testdata/ -l |
| total 20 drwxr-xr-x 2 root root 4096 Mar 24 02:26 manual01 drwxr-xr-x 2 pi pi 4096 Apr 10 02:54 TestFolder01 -rwxrwx--- 1 pi pi 18 Mar 24 02:10 user_guide01.txt |
16.2.1.2 Processing in Desktop Window
You can easily create folders using the [File Manager] in Desktop window.
Run the program and select the working folder you want to create the folder in the Directory Tree on the left. In this case, we will work with the "testdata" folder. Then, you can do the same thing by selecting menu File à Create New àFolder, or using the menu Create New à Folder from the popup menu that appears when you click right-mouse button on the right screen of the selected working folder.

Then, a pop-up screen to specify a name for the new folder appears. If you enter the desired folder name here and continue processing, the desired folder is created.
