8 Terminal Commands on Mac to Make Your Life Easier

Written by John

The macOS is a UNIX-based operating system. Mac Terminal makes it possible to control the system with a command-line interface. The average user should have no reason to use Terminal. However, if you want to know some neat little tricks, shortcuts, and have the power to tweak almost everything on your computer, you need to know Mac Terminal commands.

When you use Terminal commands for Mac, be sure that you understand what you’re typing. The scripts you enter are powerful and if you’ve made a change you didn’t want to, it can be an inconvenience when you have to figure out what went wrong and go back to revert the change.

If you’re really interested in getting more out of Terminal, you can learn to do more with time as you create your own scripts and customize your Mac according to your needs. However, most users don’t need to go to the advanced level and can still enjoy using their Mac.

Terminal on Mac?

Before we look into some commands on Mac that will make your life easier, let us understand a little more about Terminal.

Mac Terminal is an application you can find in the Utilities folder in Applications. You can launch it like you launch other applications. It is a UNIX command-line environment also known as a shell. There are different types of shell and the one on Mac is called Bash.

When you launch Terminal, you will see the name of the current user, shell type, and window size in pixels on the title bar. Inside the window, the command line starts with the name of the Mac and the current user. You will see a blinking cursor indicating the location where your command will be entered.

How to use Terminal Commands on Mac

1. Man

Man Command

Mac Terminal allows you to see manual pages or man pages through a command called a pager. The pager command allows you to view content in Terminal. However, you cannot see the entire page at once and have to scroll down to see more content.

You can use the less command to navigate the page. Press Return to move the page down one line. Press the spacebar to scroll one page down.

Type man rsync in Terminal and press Return. The rsync command’s man page is long and you need to use the spacebar several times to reach the end of the document.

If Terminal settings allow, you can scroll up the document. If not, you can use Control+B to go back one page and use Control+F or the spacebar to go one page forward. Press "Q" to close man page.

2. Diskutil

Diskutil terminal commands

If you want to manage the drives in your Mac, instead of going to Disk Utility, you can use the diskutil command. Using a simple command to format and erase disks is more convenient than following a few steps and using Disk Utility to complete the process.

Using diskutil command is simple. You can just enter the command and press Return key for Mac to list all the functions that can be performed with the command.

You can list disks, mount, format, unmount, and erase using simple commands. You will realize how easy these Mac Terminal commands make your tasks.

7. Identify Network
