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

# kill 
### Definition:
The `kill` command is used on Linux shell to terminate processes without having to log out or reboot the computer. Hence, it is specifically important to the stability of such systems.
### Syntax:
```shell
kill [signal or option] PID(s)
```
### Example:
If it is required to terminate the process with **PID** 468:
```shell
kill 468
```

If this fails, a stronger signal **9** (SIGKILL) should be used.
```shell
kill 9 468
```

There are more than **60** signals that can be used with the command `kill`. The whole list can be viewed bu using `kill` along with its option `-l`:
```shell
kill -l
```
