The Terminal app allows you to control your Mac using a command prompt. Why would you want to do that? Well, perhaps because you’re used to working on a command line in a Unix-based system and prefer to work that way. 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. Once you’ve done that, you can dig deeper and learn more commands and use your Mac’s command prompt for more complex, as well as some fun, tasks.

Terminal app can be daunting at first, but it’s really the best way to hack into your Mac’s configurations and preferences to customize things to work for you rather than against you. An easier way of completing the command is to enter the first part of it and, for the location, just drag a hard drive from your desktop to the Terminal window. Remove Duplicate “Open With”. A common bug in OS X is seeing duplicate apps within the “ Open With ” menu which can get quite full.
The Terminal app is in the Utilities folder in Applications. To open it, either open your Applications folder, then open Utilities and double-click on Terminal, or press Command - spacebar to launch Spotlight and type 'Terminal,' then double-click the search result.
You’ll see a small window with a white background open on your desktop. In the title bar are your username, the word 'bash' and the dimensions of the window in pixels. Bash stands for 'Bourne again shell'. There are a number of different shells that can run Unix commands, and on the Mac Bash is the one used by Terminal.
If you want to make the window bigger, click on the bottom right corner and drag it outwards. If you don’t like the black text on a white background, go to the Shell menu, choose New Window and select from the options in the list.
If Terminal feels complicated or you have issues with the set-up, let us tell you right away that there are alternatives. MacPilot allows to get access to over 1,200 macOS features without memorizing any commands. Basically, a third-party Terminal for Mac that acts like Finder.
For Mac monitoring features, try iStat Menus. The app collects data like CPU load, disk activity, network usage, and more — all of which accessible from your menu bar.
Basic Mac commands in Terminal
The quickest way to get to know Terminal and understand how it works is to start using it. But before we do that, it’s worth spending a little time getting to know how commands work. To run a command, you just type it at the cursor and hit Return to execute.
Every command is made up of three elements: the command itself, an argument which tells the command what resource it should operate on, and an option that modifies the output. So, for example, to move a file from one folder to another on your Mac, you’d use the move command 'mv' and then type the location of the file you want to move, including the file name and the location where you want to move it to.
Let’s try it.
Type cd ~/Documentsthen and press Return to navigate to your Home folder.
Type lsthen Return (you type Return after every command).
You should now see a list of all the files in your Documents folder — ls is the command for listing files.
To see a list of all the commands available in Terminal, hold down the Escape key and then press y when you see a question asking if you want to see all the possibilities. To see more commands, press Return.
Unix has its own built-in manual. So, to learn more about a command type man [name of command], where 'command' is the name of the command you want find out more about.
Terminal rules
There are a few things you need to bear in mind when you’re typing commands in Terminal, or any other command-line tool. Firstly, every character matters, including spaces. So when you’re copying a command you see here, make sure you include the spaces and that characters are in the correct case.
You can’t use a mouse or trackpad in Terminal, but you can navigate using the arrow keys. If you want to re-run a command, tap the up arrow key until you reach it, then press Return. To interrupt a command that’s already running, type Control-C.
Commands are always executed in the current location. So, if you don’t specify a location in the command, it will run wherever you last moved to or where the last command was run. Use the cdcommand, followed by a directory path, like in Step 1 above, to specify the folder where you want a command to run.
There is another way to specify a location: go to the Finder, navigate to the file or folder you want and drag it onto the Terminal window, with the cursor at the point where you would have typed the path.
Here’s another example. This time, we’ll create a new folder inside your Documents directory and call it 'TerminalTest.'
Open a Finder window and navigate to your Documents folder.
Type cd and drag the Documents folder onto the Terminal window.
Now, type mkdir 'TerminalTest'
Go back to the Finder, open Text Edit and create a new file called 'TerminalTestFile.rtf'. Now save it to the TerminalTest folder in your Documents folder.
In the Terminal window, type cd ~/Documents/TerminalTest then Return. Now type lsand you should see 'TerminalTestFile' listed.
To change the name of the file, type this, pressing Return after every step:
cd~/Documents/Terminal Test
mv TerminalTestFile TerminalTestFile2.rtf
That will change the name of the file to 'TerminalTestFile2'. You can, of course, use any name you like. The mv command means 'move' and you can also use it to move files from one directory to another. In that case, you’d keep the file names the same, but specify another directory before typing the the second instance of the name, like this:
mv ~/Documents/TerminalTest TerminalTestFile.rtf ~/Documents/TerminalTest2 TerminalTestFile.rtf
More advanced Terminal commands
Terminal can be used for all sorts of different tasks. Some of them can be performed in the Finder, but are quicker in Terminal. Others access deep-rooted parts of macOS that aren’t accessible from the Finder without specialist applications. Here are a few examples.
Copy files from one folder to another
In a Terminal window, type ditto [folder 1] [folder 1] where 'folder 1' is the folder that hosts the files and 'folder 2' is the folder you want to move them to.
To see the files being copied in the Terminal window, type -v after the command.
Download files from the internet
You’ll need the URL of the file you want to download in order to use Terminal for this.
cd ~/Downloads/
curl -O [URL of file you want to download]
If you want to download the file to a directory other than your Downloads folder, replace ~/Downloads/ with the path to that folder, or drag it onto the Terminal window after you type the cd command.
Change the default location for screenshots
If you don’t want macOS to save screenshots to your Desktop when you press Command-Shift-3, you can change the default location in Terminal
defaults write com.apple.screencapture location [path to folder where you want screenshots to be saved]
Hit Return
killall SystemUIServer
Hit Return
Change the default file type for screenshots
By default, macOS saves screenshots as .png files. To change that to .jpg, do this:
defaults write com.apple.screencapture type JPG
Press Return
killall SystemUIServer
Press Return
Delete all files in a folder
The command used to delete, or remove, files in Terminal is rm. So, for example, if you wanted to remove a file in your Documents folder named 'oldfile.rtf' you’d use cd ~/Documents to go to your Documents folder then to delete the file. As it stands, that will delete the file without further intervention from you. If you want to confirm the file to be deleted, use -i as in rm -i oldfile.rtf
To delete all the files and sub-folders in a directory named 'oldfolder', the command is rm -R oldfolder and to confirm each file should be deleted, rm -iR oldfolder
Just because you can use Terminal to delete files on your Mac, doesn’t mean you should. It’s a relatively blunt instrument, deleting only those files and folders you specify.
Another way to free up space
If your goal in removing files or folders is to free up space on your Mac, or to remove junk files that are causing your Mac to run slowly, it’s far better to use an app designed for the purpose. CleanMyMac X is one such app.
It will scan your Mac for files and recommend which ones you can delete safely, as well as telling you how much space you’ll save. And once you’ve decided which files to delete, you can get rid of them in a click. You can download CleanMyMac here.
As you can see, while Terminal may look scary and seem like it’s difficult to use, it really isn’t. The key is learning a few commands, such as those we’ve outlined above, and getting to know the syntax for those commands.
However, you should be careful when using Terminal, it’s a powerful tool that has deep access to your Mac’s system files. Check commands by googling them if you’re not sure what they do. And if you need to delete files to save space, use an app like CleanMyMac X to do it. It’s much safer!

Welcome back to Coding Corner! Today, we're going to go over some great interface and user tweaks you can execute to customize your Mac. These tricks are often simple and can help you spruce up your Mac far beyond what the System Preferences window allows.
So, without further ado, 15 great tricks you can execute in Terminal.
Tweak the Finder
Want to see hidden files, or copy Quick Look text? There are quite a few 'defaults' commands that let you alter how the Finder looks or acts.
1. Show hidden files and folders
Want to see all the hidden files and folders OS X has to offer — or you simply can't find a file you hid? Just use this command in Terminal:
defaults write com.apple.finder AppleShowAllFiles -bool TRUEkillall Finder
To re-hide all your files, just change the TRUE to FALSE.
2. View any file's contents
If you've had a file get corrupted or you suspect there's something hidden inside its package, you can force Terminal to open it. Just use the following command:
cat ~/enter/file/path
Fair warning: If you try to open a photo or pretty much any non-text document, you'll likely just see text gibberish.
3. Copy the contents of a folder from one place to another
Sure, you can Option-drag any file to a new location to make a copy of it, but if you want to simplify the process and automatically copy the entire contents of one folder to another, check out this simple Terminal trick.
ditto -V ~/original/folder/ ~/new/folder/
4. Download files outside of your browser
Have the URL to a file but don't want to use Safari, Firefox, or Chrome to download it? You can go through Terminal with the following commands:
cd ~/Downloads/curl -O http://www.thefilename.com/thefile/url.mp3
The first command moves your current Terminal location to your Downloads folder; the second downloads it from the web to that folder.
Modifying screenshots
Want to change how your screenshots look? Here are some commands to help you do just that.
5. Change your screenshot's file format
This Terminal command lets you change the file format of your screenshots. By default, they're saved as PNGs, but you can also save them as PDFs, JPGs, and more.
defaults write com.apple.screencapture type jpg
6. Disable drop shadows on a screenshot
Here's another good one if you tend to take a lot of screenshots: This command will disable drop-shadow on your screenshots, only displaying the window you've snapped.
$ defaults write com.apple.screencapture disable-shadow -bool TRUEkillall SystemUIServer
7. Create a new default name scheme for screenshots
Don't like the phrase Apple uses to save your screenshots? Traditionally, it's 'Screen Shot - [date] - [time]', but you can change 'Screen Shot' to any word you please.
defaults write com.apple.screencapture name 'New Screen Shot Name'
killall SystemUIServer`
Get bored of your new name scheme? Go back to the default by typing as follows:
defaults write com.apple.screencapture name 'killall SystemUIServer
8. Change the location of your screenshots
Your screenshots, by default, save to the Desktop. But if you'd prefer they save elsewhere, it's an easy Terminal trick to make it so.
defaults write com.apple.screencapture location ~/your/location/herekillall SystemUIServer
You can also drag the folder of your choice on top of the Terminal window after typing 'location' if you don't want to manually type out the file path.
System changes
If you're looking for broader OS X-level changes, these commands might help you get started.
9. Create a custom login message
Whether you want to troll your friends or add useful 'in case of loss' contact information, you can add a personalized message to your login screen with this Terminal command.
sudo defaults write /Library/Preferences/com.apple.loginwindow LoginwindowText 'In case of loss, call 555-555-5555.'
10. How long has my Mac been running?
Is your Mac acting sluggishly? It might be in need of a good restart. You can check to see just how long your Mac's been active by checking its uptime with this Terminal command:
uptime
11. Keep your Mac awake
If you need to prevent your Mac from going to sleep — say, you're running an extensive task, or recording your screen — there's an all-too-amusing command for that:
caffeinate
Once you enter this command, your Mac's digital eyes will be pried open and prevented from going to sleep until you end it by pressing Control-C.
If you don't want to rely on being the one to end your poor Mac's suffering, you can also create a set a number of seconds before your Mac sleeps:
caffeinate -u -t 5400
The above command will keep your Mac awake for an hour and a half.
12. Make your Mac automatically restart after a crash
We've all had our Mac freeze up or crash at least once in its lifetime. If you want to skip the crying and the yelling at the screen and get back to work, you can enter this Terminal command, which will make OS X reboot as soon as it senses a full system freeze.

15. Hide non-active apps in your Dock
If lowering the opacity of hidden apps appeals to you, you might like this Terminal command even better: It hides any closed app from your Dock at all times.
defaults write com.apple.dock static-only -bool TRUEkillall Dock
