How to install

There is no need to install the rmdir command, as it is built into most Linux distributions.

However, if for some reason the rmdir command is missing or unavailable on your system, you can install it as follows:

1. Make sure that you have superuser (root) or administrator rights.
2. Open a terminal or console and run the following command depending on your distribution.
3. For Debian-based distributions (Ubuntu, Linux Mint, etc.): sudo apt-get install coreutils
4. For Red Hat-based distributions (Fedora, CentOS, etc.): sudo dnf install coreutils or sudo yum install coreutils
5. For distributions based on Arch Linux (Manjaro, etc.): sudo pacman -S coreutils
6. After executing the installation command, the rmdir command should be available and ready to use.

Note that the rmdir command may also be available in other packages, so you can use your distribution's package manager to find and install a package containing this command.
