The Unix Survival Kit: A List of Must-Know Commands for Every User
The Unix operating system is a powerful platform that is used by millions of people around the world.
It provides a command-line interface that allows users to enter commands and interact with the operating system.
In this article, we will take a look at some of the basic commands that are commonly used in Unix.
| Command | Description |

| ls | This command is used to list the files and directories in a directory. You can use the -l option to display the files in a long format, which includes additional information such as the file size, permissions, and modification date. |
| cd | This command is used to change the current working directory. For example, to change to the /home/user directory, you would enter cd /home/user. |
| pwd | This command is used to display the current working directory. It is often used to verify that you are in the correct directory before running other commands. |
| mkdir | This command is used to create a new directory. For example, to create a new directory called newdir, you would enter mkdir newdir |
| cp | This command is used to copy files and directories. For example, to copy the file file.txt to the directory /home/user, you would enter cp file.txt /home/user. |
| mv | Renames or moves a file. |
