You can use the command-line environment interactively by typing a command and waiting for a result, or you can use the shell to compose scripts that run without direct interaction.

Execute commands in the shell

1. Terminal is a Mac command line interface. There are several advantages to using Terminal to accomplish some tasks — it’s usually quicker, for example. In order to use it, however, you’ll need to get to grips with its basic commands and functions.
2. This is a reference to the article “Mac stuck on Gray Screen with apple logo during boot after installing macOS Sierra“. These are the terminal command that I used in recovery mode when my Mac was unable to boot due to low disk space. I though of publishing the whole terminal commands output to those.

• In the Terminal app on your Mac, enter the complete pathname of the tool’s executable file, followed by any needed arguments, then press Return.

If a command is located in one of the shell’s known folders, you can omit path information when entering the command name. The list of known folders is stored in the shell’s PATH environment variable and includes the folders containing most command-line tools.

Fortunately, not all commands are scary. In this piece, we’ll show you ten commands you can perform with Terminal that could be of use to you now, or in the future. Ten fun and useful Terminal commands to use in macOS. Check server response. Ping is probably one of the more useful Terminal commands that an everyday Mac user might actually use. To update macOS from the command line, first launch Terminal, which can be found in the Applications/Utilities folder. This will open a Terminal window and a command prompt for you to begin typing.

For example, to run the ls command in the current user’s home folder, enter the following at the command prompt, then press Return:

To run a command in the current user’s home folder, precede it with the folder specifier. For example, to run MyCommandLineProg, use the following:

To open an app, use the open command:

When entering commands, if you get the message command not found, check your spelling. Here’s an example:

Terminate commands

1. In the Terminal app on your Mac, click the Terminal window that is running the command you want to terminate.

2. Press Control-C.

   This sends a signal that causes most commands to terminate.

Repeat previously entered commands

The commands you enter during a session are saved so you can repeat a previously used command without retyping it.

1. In the Terminal app on your Mac, press the Up Arrow key.

   The last command you entered appears on the command line.

2. Continue pressing the Up Arrow key until you see the command you want, then press Return.

For those who have never used Terminal commands on Mac before, the app’s resemblance to hacking (as seen in movies) can be a little intimidating. But in fact, Terminal isn’t all that complicated once you know a little about how it works.

Many commands are surprisingly straightforward, such as how to open a file in Terminal and the dangerously powerful (since it bypasses the Trash) Terminal delete file capability:

open ~/Desktop/filename.extension

rm filename.extension

The rm stands for remove, so use with caution!

For another example, let’s look at how to create a folder on Mac. Using Finder, this would simply be a case of right-clicking and choosing New Folder. When it comes to how to make a directory in Terminal, we’d need to use a specific command:

mkdir 'new folder'

The Terminal window itself is designed to grant users access to UNIX features hidden away behind the Mac operating system. But you don’t need to learn about all of the technical stuff if you don’t want to. All you need to know is that a bit of Mac command line rote learning can help you do all sorts of cool things with your laptop or desktop that you couldn’t achieve otherwise.

8 Best Terminal Commands For Mac

Of course, defining the best Terminal commands for Mac really depends on what you want to get out of this tool. First things first though, to start you need to know how to open command prompt on Mac because you can’t use any Terminal commands without it:

1. Double-click your Macintosh HD icon or open a Finder window

2. Make your way into the Applications folder

3. Double-click Utilities and open Terminal

You’ll be met with a window that shows the name of your Mac followed by your username and a $ sign. All of the Mac Terminal commands listed here are entered after this, followed by a press or two of the Return key.

Actually using the app may be a bit tricky if you’ve never done so before, but at least the question of how to open Terminal on Mac is easy to answer. Pay attention going forward!

1. Show or hide files and folders

One of the easier, and most useful, commands to use in conjunction with Mac command line is the one that reveals hidden files and folders in macOS:

defaults write com.apple.finder AppleShowAllFiles -bool TRUE

killall Finder

Now you can edit and delete files that were previously inaccessible. When you want to hide these files again, just change the TRUE above to FALSE and repeat the process.

2. Duplicate files between folders

Rather than dragging and dropping or copying files between folders, you can use Ditto Terminal command on Mac to achieve the same result:

Ditto [original folder] [new folder]

If you have folders in different locations with the same name, you can type -v after Ditto to display each item’s file path using the verbose mode of Mac Terminal.

3. Change default screenshot settings

Tired of clogging up your desktop with screenshots? Terminal on Mac offers an easy fix for that with the option to set a new location for screenshots to be saved. Just enter the following:

defaults write com.apple.screencapture location ~/your/desired/location

killall SystemUIServer

You can also change the default file format (PNG) if you want to generate screenshots as JPEGs or PDFs instead:

defaults write com.apple.screencapture type jpg

4. Improve the screenshot process

If you take a lot of screenshots on your Mac, you might have noticed that it automatically adds a drop shadow to screenshotted windows. If you’d prefer to turn these shadows off, you can do so with the following Mac commands:

$ defaults write com.apple.screencapture disable-shadow -bool TRUE

killall SystemUIServer

To further customize how screenshots appear on your Mac, you could look at CleanShot. This app allows you to capture your Mac’s screen without the distraction of desktop icons, set custom wallpapers on the background, and annotate or blur certain parts of the image.

After taking a screenshot with CleanShot, a small popup window allows you to tweak the appearance of your capture — such as adding shapes, text, or pixelating parts of the image — before you share it anywhere using a layout similar to the simple and intuitive actions in Preview.

5. Download files without using your browser

The art of downloading files without using a web browser is familiar to any millennials who risked malware and viruses to download their favorite tracks from Limewire or Kazaa, but may be unheard of to others.

A nifty Mac command line trick exists for downloading files without using your web browser if you already know the location of the file. The command is as follows:

cd ~/Downloads/

curl -O http://awebsite.com/folder/fil..

The first part is a crash course in how to change directory in Terminal, as that’s what the cd stands for. So by re-reading the example above, you can see that the file will appear in your Downloads folder when it’s finished downloading.

6. Keep your Mac awake

Overriding your Mac’s default sleep settings (available via System Preferences ➙ Energy Saver) is a breeze using one of Terminal’s more humorous Mac commands. Apparently, like so many people out there, Macs run on coffee:

caffeinate -u -t [number of seconds to remain active]

If you’d rather not launch Terminal every time you need to keep your Mac awake, there’s an app out there called Lungo that lives in your menu bar and builds on the coffee theme. Just select the cup icon in the top right corner of your screen and you can keep your Mac awake for 10 minutes, 30 minutes, 1 hour, 4 hours, or indefinitely with a single click.

7. View the contents of any folder or file

If one of your files gets corrupted, or you suspect there’s a hidden message tucked away somewhere inside its package, you can use the Terminal window to see some details about it:

cat ~/file/path/here

The command will throw out a bunch of indecipherable nonsense if you try to use it on something like an image or an audio file, but it could be a lifesaver when recovering text from a corrupted Word document, for example.

8. Hide inactive apps in Dock and dull hidden ones

Accruing more and more apps in your Dock is pretty much par for the course when you use a Mac for any significant length of time. So a good-to-know Terminal command here is the one that makes your Dock embrace a minimal approach by showing only active apps:

defaults write com.apple.dock static-only -bool TRUE

killall Dock

If you want to take this process even further, you can dim apps that aren’t visible on your monitor(s):

defaults write com.apple.Dock showhidden -bool TRUE

killall Dock

Another easier option for those with the cluttered Dock is to check out uBar, a simple and minimal replacement. Instead of a long line of icons, you can now have a highly customizable bar that allows you to devote more space to the apps that matter most.

You can use uBar to preview, group, quit, or close apps and windows, without the need to open them first, across multiple monitors. It’s an altogether less distracting option for those who find the default Dock a bit cluttered or unpredictable.

Best Terminal for Mac alternatives

If you simply can’t get to grips with how to open Terminal on Mac or get comfortable with all of its ins and outs, you may want to investigate an app like MacPilot.

MacPilot grants access to more than 1,000 hidden features in macOS using UNIX without requiring that you learn any complicated commands. Instead, it offers users a Finder-esque window that groups tweaks by both application and function.

In most cases, enabling or disabling features with MacPilot is as simple as checking or unchecking the relevant boxes. You can also explore content across your disks using a File Browser that includes hidden files and detailed information about all available items.

The range of System Tools, reference guides, and secret tricks offered by MacPilot is a powerful alternative to Terminal for those who would rather avoid struggling with commands.

Why the Terminal window still matters

Try to wax lyrical about the benefits of Mac commands with fellow Apple users and there’s a good chance you’ll be met with them asking “what is a Terminal?” The fact is, this app isn’t something that the average Mac user ever bothers much with.

As you can see from the list of useful commands above, neglecting to use Terminal on Mac or an app like MacPilot means never seeing everything that your laptop or desktop is capable of.

Fun Terminal Commands For Mac

One of many great things about using Mac Terminal commands is that, should you make a mistake, you can usually undo whatever you’ve done just by changing TRUE to FALSE and running the command again or simply changing the location or setting back to what it was before.

It’s true that Mac Terminal has a steep learning curve if you’re not used to its “language” but, whether or not you take the easier route with MacPilot, you can still try some of the cool tricks Terminal allows. You can play games, for example, by doing the following:

1. Open a Terminal window and type emacs then press Enter

2. With GNU Emacs selected, hit Escape

3. On the next screen, type x then tetris, pong or snake and press Enter
