Kali Linux is a Debian-based Linux distribution designed for penetration testing and security auditing. It comes with a wide range of tools and utilities that can be used to assess the security of computer systems and networks.
One of the most important aspects of using Kali Linux is being able to use the command line. The command line is a powerful tool that can be used to perform a wide range of tasks, such as installing and configuring software, managing files and directories, and troubleshooting problems.

- Use the ? character to get help for a particular command.
- Use the ! character to recall and execute a previous command.
- Use the ; character to execute two or more commands on the same line.
- Use the & character to execute a command in the background.
- Use the | character to pipe the output of one command to the input of another command.
With a little practice, you will be able to use the command line in Kali Linux to perform a wide range of tasks.
