Opening Terminal
To open Terminal, you can use Spotlight by pressing Command + Spacebar and typing “Terminal” in the search bar. Alternatively, you can open it from the Utilities folder, which is located in the Applications folder.
Basic Commands
Once you have opened Terminal, you will see a command prompt. This is where you can enter commands. Here are some basic commands to get you started: – cd: This command allows you to change the current directory. – ls: This command lists the contents of the current directory. – mkdir: This command creates a new directory. – rm: This command removes a file or directory. – touch: This command creates a new file.
Using Tab Completion
One of the benefits of using Terminal is the ability to use tab completion. This means that you can start typing a command or file name and then hit the tab key to complete it. This can save you a lot of time and effort.
Customizing Your Terminal
You can customize your Terminal by changing the font, color, and other settings. To do this, go to Terminal > Preferences. From there, you can adjust the settings to your liking.

Redirecting Output
You can redirect the output of a command to a file or another command. This can be useful when you want to save the output for later use or when you want to pipe the output to another command. Here’s how to redirect the output: – >: Redirects output to a file. – |: Pipes output to another command.
Using Environmental Variables
Environmental variables are values that are set in the Terminal environment and can be used by commands. Here are some common environmental variables and their uses: – HOME: The user’s home directory. – PATH: A list of directories that the system searches for executables. – USER: The current user’s username.
Using Aliases
You can create aliases for commonly used commands to save time. Here’s how to create an alias: alias name='command' For example, if you want to create an alias for the ls command: alias l='ls -l' Now, every time you type l, it will run the ls -l command.
Using Scripts
