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

# mkdir
## Definition: 
`mkdir` is one of the most important directory manipulation commands. It's short for 'make directory' and as the name suggests, it is used for creating new directories within the current directory. You can create any number of directories with this command. It takes the directory name as an argument. 
## Syntax: 

```
mkdir [options][dir_name]
```

## Options: 
`mkdir` in terminal can take two options:
| **Option** | **Meaning** |
| --- | --- |
| -p | Means Parent or Path. It is used when we want to create a directory within a directory that doesn't already exist |
| -m | Means Mode. It is used to specify and control permission modes |

## Example: 
```
mkdir my_dir_1 my_dir_2 my_dir_3
```

This lesson will enable you to create directories through command line interface.
