What is the rmdir Command in Linux?
The rmdir command in Linux is designed specifically to remove empty directories.Its name is “remove directory,” and its main objective is to assist users in organising their file system by getting rid of directories that are no longer needed. The rmdir command only functions if the targeted directory is empty, in contrast to the rm command, which is used to delete files and directories that contain content. The rmdir command will display an error message if the directory has any files or subdirectories..
How to Use the rmdir Command in Linux
Using the “rmdir” command in Linux is simple. The basic syntax for the command is as follows:
| rmdir [directory] |
In this case, “[directory]” stands for the name of the directory you want to remove. To remove a directory named “test,” for instance, you would issue the following command:
| Rmdir test |
It’s crucial to remember that in order to delete the relevant directory, you must have the proper rights. The “rmdir” command will return an error if the proper permissions are not present.
Options for the rmdir Command in Linux
There are several options that can be used with the “rmdir” command in Linux. These options include:
- -p: This option allows you to delete a directory and all of its parent directories, as long as they are empty.
- -v: This option displays the name of each directory that is being deleted.
- –ignore-fail-on-non-empty: This option tells the “rmdir” command to ignore non-empty directories and continue with the deletion of other directories.
Examples of Using the rmdir Command in Linux
Here are a few examples of how the “rmdir” command can be used in Linux:
- To delete a single empty directory:
| rmdir test_directory |
- To delete multiple empty directories:
| rmdir test_directory1 test_directory2 test_directory3 |
- To delete a directory and all of its parent directories:
| rmdir -p test_directory/test_subdirectory/test_subsubdirectory |
