Introduction
Before we discuss rmdir command in Linux, let's briefly understand - What is rmdir command ?
The rmdir command on Linux is used to remove directories or folders from the file system. It is a built-in command that helps users delete empty directories quickly and efficiently.
Unlike the rm command, which deletes files, rmdir focuses specifically on removing directories. By using rmdir, users can clean up their directory structure and streamline their file system organization, making it a convenient tool for managing directories with ease.
In this tutorial, you will understand rmdir command in Linux. We will also address a few FAQs on rmdir command in Linux.
Introduction to rmdir Command
In Linux, empty directories are specifically meant to be removed using the rmdir command. rmdir only works with directories, as opposed to the rm command, which can remove both files and directories. It's a simple tool, but it's essential for keeping your system's directory structure organized.
Basic Syntax
The rmdir command's basic syntax is as follows:
rmdir [option] directory_nameThe name of the directory you wish to remove is indicated by directory_name in this case.
rmdir Command
Similar to the rm command, the rmdir command only deletes empty directories. Therefore, we will first list all the options available for the rmdir command using the help flag:
rmdir --helpThe command above shows the different options, including:
Understanding Options
-p, --parents: When the specified directory is removed, this option allows parent directories to be removed as well, in case they become empty. If the parent directories of the directory become empty, it effectively removes both of them.-v, --verbose: When activated, this option gives feedback on the action taken by displaying a message for every directory processed.--ignore-fail-on-non-empty: By default, if the directory is not empty,rmdirfails. This option, however, forcesrmdirto carry out the removal despite such errors.--version: This option shows the version details and closes the window.
Exit Status
This command returns the following exit values:
| Item | Description |
|---|---|
0 | The operation to remove each directory entry specified by the Directory parameter was completed successfully. |
>0 | An error occurred. |
Example 1: The Basic rmdir Command
To begin the examples, let's create a section using the basic rmdir command to remove multiple directories. The syntax is as follows:
rmdir mydir1 mydir2 mydir3 .....Here, we'll use the following command to delete the LINUX, INFO, and DETAIL directories:
rmdir LINUX INFO DETAILExample 2: The -p Option
The rmdir command can be used with the -p option to remove a directory along with all of its subdirectories:
rmdir -p mydir1/mydir2/mydir3/...../mydirNFor instance, we will use the following command to remove the LINUX directory and all of its ancestors:
rmdir -p LINUX/mydir1/mydir2/mydir3Example 3: The -v Option
You can use the -v option with the rmdir command to have the message displayed in the terminal after the directory is removed:
rmdir -v dir1 dir2 dir3Now that the LINUX, INFO, and DETAIL directories have been successfully removed, let's delete them and display the following message:
rmdir -v LINUX INFO DETAILrmdir: removing directory, 'LINUX'rmdir: removing directory, 'INFO'rmdir: removing directory, 'DETAIL'Example 4: Remove Multiple Directories With the Same Expression
If several directories have the same expressions, you can delete them all by using the * in the rmdir command. For illustration, let's delete every directory whose name includes LINUX:
ls LINUX1LINUX2LINUX3rmdir -v LINUX*rmdir: removing directory, 'LINUX1'rmdir: removing directory, 'LINUX2'rmdir: removing directory, 'LINUX3'The ls command was used in the command above to list every directory that is available. Additionally, we used the rmdir command with the -v option and * to remove every directory that contained the same expression.
Example 5: The --ignore-fail-on-non-empty Option
When using the rmdir command to remove a directory, you may occasionally encounter the following error:
rmdir <option> <directory> rmdir: failed to remove 'dir1': Directory not emptyTo ignore the occurrences caused by the non-empty directories in this situation, use the --ignore-fail-on-non-empty option. Let's take out the LINUX directory, for example, which has the following subdirectories:
rmdir --ignore-fail-on-non-empty LINUXFAQs on rmdir command on Linux
