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
```
