Before we dive into the important Linux commands, let's quickly go over what Linux commands are. Linux commands are instructions that you can give to your computer to perform specific tasks. They are entered into the command line interface, also known as the terminal.
Now, let's get down to business and explore some of the important Linux commands that every beginner should know:
1. ls - This command lists the files and directories in the current directory. It's like a window into your file system.
2. cd - Use this command to change directories. For example, if you want to navigate to the "Documents" directory, you would type cd Documents.
3. mkdir - This command is used to create a new directory. Simply type mkdir directory_name to create a new directory with the specified name.
4. rm - Use this command to remove files and directories. Be careful with this one, as it permanently deletes the specified files or directories. To remove a file, type rm file_name. To remove a directory and its contents, use the -r flag, like this: rm -r directory_name.
5. cp - This command is used to copy files and directories. To copy a file, type cp source_file destination_file. To copy a directory and its contents, use the -r flag, like this: cp -r source_directory destination_directory.
6. mv - Use this command to move or rename files and directories. To move a file, type mv source_file destination_directory. To rename a file, simply provide the new name as the destination, like this: mv old_name new_name.
7. cat - This command is used to display the contents of a file. Just type cat file_name and the contents of the file will be printed in the terminal.
8. grep - Use this command to search for specific text within files. For example, if you want to find all occurrences of the word "hello" in a file, you would type grep "hello" file_name.
9. chmod - This command is used to change the permissions of files and directories. It's a bit more advanced, but it's good to know. To change the permissions of a file, type chmod permissions file_name. The permissions can be specified using numbers or symbols.
These are just a few of the important Linux commands that every beginner should know. As you continue to explore Linux, you'll discover many more commands that can help you become a Linux pro.
