Cloud management: key points and top tools

What is a Terminal on Mac

As it turned out, huge amounts of search queries concerning the topic “Terminal on Mac”, “Mac hacks Terminal” appear on the Internet almost every day. Moreover, many people want to find out how to run Terminal in the Apple operating system. As it is well known, a regular user has no reason to use or even open Terminal, an Apple Command Line interface application, but it’s worth a try because, in fact, it gives access to many tricks and shortcuts. So, let’s start.

It is a well - known fact that Apple has its own Mac Command Line interface, in which you can easily and quickly manage tasks than perform a normal and long process. However, its interface looks rather specific, especially if you do not have the technical knowledge or any clue how to use the Terminal on Mac. However, once you take a look at this useful application, you will surely like it. Who knows?

Terminal is a standard system utility for interacting with Mac using the Command Line. Linux has a similar management tool because both operating systems are Unix-like. In brief, all you need to know about the Terminal is that it is an application that allows you to control your computer using commands, besides that opens the possibility to work with locked functions, etc.

How to open Terminal on Mac

For the record, there are several ways to open Mac Terminal. Choose the one that meets your requirements the most.

Terminal window

1. How to open Command Line on Mac via the Dock

There is usually “Applications” shortcut on the Dock panel on macOS. Click on it and a list of all installed programs on your Mac will be open. Find and open the “Utilities” folder, inside you will find the “Terminal” app. Run it. Please note that in recent versions of Mac OS X, this shortcut is called Launchpad.

2. Opening Terminal through the Finder

Open Finder (in the Dock it is always on the left). In the left menu, select "Applications" and in the list of all programs that open, find the directory/folder "Utilities". Click on it and search for the application "" in it. Double-click the Terminal.

3. Opening Terminal on Mac through the Spotlight search bar

Hold down the Ctrl + Spacebar key combination at the same time. In the pop-up window, enter the word "Terminal". Once you have typed you will see the application you need, all you need is just click it.

4. Basic Terminal Mac shortcuts

  • Command (⌘) + T is used in order to open a new terminal window.
  • Command (⌘) + N is used in order to open a new tab in the terminal.
  • Command (⌘) + Shift + T is used to switch tabs back and forth.

Mac Terminal tricks you should know

Mac OS Terminal can do a lot, from moving a lot of files to changing preferences that we couldn't even think of. To demonstrate what Terminal can do, we have put together 17 really excellent tips and tricks that you might find useful.

1. Enable showing hidden files and folders

If you want to see all the folders and files hidden by the system, then run the following command in the Terminal:

defaults write AppleShowAllFiles -bool TRUE && killall finder

Tip: To hide them back, change the value from TRUE to FALSE.

2. View the contents of any files

If you have a damaged file or you suspect that something else is hidden inside it, then you can force the Terminal to open it, despite the failure of normal applications, with the corresponding command:

cat ~/path/to/file

Be careful, if you try to open a photo or any other non-text document, you will see a wall of illegible characters.

3. Copy the contents of a folder from one location to another

Of course, you can just copy-paste the entire contents of the folder, but in cases where you need to simplify and / or automate this process, the following Mac Terminal command will help you:

ditto -V ~/source/folder/ ~/new/folder/

4. Changing the file format of screenshots

While using Terminal on Mac, you can change the format of screenshots from PNG to any other, including PDF and JPG:

defaults write type jpg && killall SystemUIServer

5. Disable shadows in screenshots

Those who take a lot of screenshots and want nothing extra on them can turn off the drop shadow effect and leave only the window itself being shot:

defaults write disable-shadow -bool TRUE && killall SystemUIServer

6. New names for screenshots

I absolutely do not like that boring and inconvenient format for the names of screenshots (“Screenshot date-time”), so below there will be a command that allows you to replace the word “Screenshot” with something more appropriate:

defaults write name "New name" && killall SystemUIServer

By the way, to return the setting to the original name, you need to enter this:

defaults delete name && killall SystemUIServer

7. New folder for screenshots

By default, all screenshots are saved to your desktop, clogging up valuable space. To change this, simply enter the following command from the list of Useful Terminal commands:

defaults write location ~/your/location/here && killall SystemUIServer

8. How long has my Mac been on?

When was the last time you have rebooted your computer? You can check this with a command in the Terminal:


9. Disable sleep mode

Sometimes it becomes necessary to keep the Mac awake, for example, when downloading a torrent or creating a backup. While using Mac Terminal you can disable hibernation on your Mac by typing:


Now your Mac will not fall asleep under any pretext.
Tip: For this command, you can specify the time (in seconds) after which the Mac will automatically go to sleep if it is inactive:

caffeinate -u -t 5400

10. Start auto-restart when the Mac completely freezes

Of course, it also happens: for no reason at all, the Mac freezes and you have nothing left but a forced reboot. The following command forces OS X to reboot if it realizes that the system is not responding:

sudo systemsetup -setrestartfreeze on

11. Drag and drop folders and files to automatically generate paths

One trick that saves the most time and makes using Terminal easier is automatically generating paths. Working in the Terminal, you need to enter custom file paths often. First, you have to locate the file or folder, then copy the file path into the Terminal. It can take a long time, and it’s easy to make typos.

Instead, you can grab a file or folder and drag and drop it directly into the Terminal window. This trick even works mid-command, so whenever you need a file or folder path, just grab the icon and generate it automatically when you drop it into Terminal.

12. Activate the type to talk feature

While automatically generating paths saves you a significant amount of time while working, the type-to-talk feature is mostly just for fun. When you type the say command, your Mac will repeat anything you type after it.

Mac has over 100 voices from which to pick. By adding a name to the command say -v name you can change the voice it uses to repeat the text you enter into the Terminal. There are two ways to get the list of the names:

  • Use the say -v ? command to get a list of the voice names
  • Navigate to the Accessibility menu in System Preferences:
    • - select Speech in the lefthand menu list;
    • - open the System Voice drop-down menu;
    • - select Customize;
    • - browse the voice options available and pick your favorites.

The say command recognizes periods and commas, but since the Return key executes any command, you have to type everything into a single line. Type out longer paragraphs of speech in a text document first, then copy and paste it into Terminal.

13. Repeat characters by holding down a single key

Those who use both Windows and Mac OS will notice slight differences in the keyboard functions for each operating system. It can take some adapting to the different keystroke responses of Mac. One of the most noticeable ones is holding a single key.

On macOS, holding down a single key reveals a number of variations of that character. In Windows, that same shortcut allows you to repeat that character for as long as you hold down the key.

Both are useful functions, but it’s only possible to repeat the spacebar key in macOS by holding it down in a text field. If you find you’re not using alternative characters very often (keep in mind you can always copy/paste them from Wikipedia as well), then you can permanently switch the function for Mac.

Open Terminal and type the following, and press Return to execute:

defaults write NSGlobalDomain ApplePressAndHoldEnabled -bool FALSE

Quit any open applications and restart them for the change to take effect. If you change your mind later and want to go back to the alternate characters, you can enter the same command with TRUE instead of FALSE:

defaults write NSGlobalDomain ApplePressAndHoldEnabled -bool TRUE

Remember to hit the Return key to execute the command once you have it entered.

14. Turn Text into an ASCII Banner

As a throwback to the early days of the internet, you can turn text into an ASCII banner using Terminal. ASCII art pre-dates the stylish art and graphics available now; it uses the American Standard Code for Information Interchange keyboard to create large graphics. It’s also incredibly easy to use the banner function in Terminal.

  • Launch Terminal from Utilities under Applications
  • Type:
  • Follow with the text you want to be displayed: banner your text goes here

ASCII banners default to 132 characters wide, which can look nonsensical on a computer screen. It’s easy to adjust the size of your banner using the width flag.

  • Type:
    banner -w 30

You can reduce the width of your ASCII art to any size or increase it if you want.

15. Watch Star Wars in ASCII

It should be no surprise that the MacOS programmers were fans of the sci-fi classic Star Wars. It’s possible to “watch” the first movie in the original trilogy, A New Hope, in ASCII. Use the command:

nc 23 

You can watch the entire movie in ASCII art, with text captions of the dialogue. When you’re stuck in a boring meeting or on a flight without wi-fi, it’s a good distraction.

16. Customize a Login Window Message

Whether you spend a lot of time on the computer or just use one for fun, it’s nice when your devices feel customized to you. Using Terminal, you can create your own message for the login window of your computer or create one to use on a fleet of computers for work or school. The command line is:

sudo defaults write /Library/Preferences/ LoginwindowText "Your message here"

Just log off your account or restart your computer, and the message will now greet you every time you log in to use your computer. If you want to change the message seasonally or remove it altogether, just use the command:

sudo defaults delete /Library/Preferences/ LoginwindowText

Using Terminal tricks is one way to get more computer savvy, have fun with the native features of macOS, and customize your computer to your preferences. Here’s a cheat sheet with the most commonly used Terminal commands and shortcuts.
