Gain insights into the power of the command line. Learn about Linux BASH through theoretical and practical exercises, mastering essential concepts and commands for efficient programming.

Ever wondered why command line is still in use even when there are hundreds of human-friendly GUI’s and tools available? Everyone in the programmer's world would agree on one thing: Command Line is far more powerful than any GUI. It provides a richer experience in terms of speed and expressiveness.

For beginners, it might be hard to appreciate its beauty and a little challenging to shift from an interactive interface to a blank box with just a “$” sign showing that keeps prompting the user to enter complex commands if you want to get something done. This is why we felt the need to build a course which could help the user overcome his/her fear of using the terminal (we have all been there).

The objective of this course is to help you get a strong grip over Linux, mainly focusing on BASH. You will be covering both, the theoretical and practical sides. First, you will learn a bunch of concepts necessary to understand things and then study some nifty commands to get useful things done out of them.

Bash for Programmers

# rmdir
## Definition: 
`rmdir` is the opposite of `mkdir`. It is used to remove the directory name given in the argument. This command is mainly used to remove empty directories. Just like you can make muliple directories at the same time, you can also delete multiple directories simultaneously by passing their names as arguments. 
## Syntax: 
```
rmdir [option] [dir_name]
```
## Options: 
`rmdir` in terminal can take two options:
| **Option** | **Meaning** |
| --- | --- |
| -p | This option tells rmdir to remove nested directories if they become empty after deleting previous directory|
| -v or verbose | Verbose mode outputs after every directory operation that you perform|

## Example: 
```
rmdir my_dir_1 my_dir_2 my_dir_3
```
