- How To Use Mac Terminal
Open Terminal (several ways) On the Mac, the Terminal app is kinda buried, probably perhaps because those who use a MacOS laptop just for social media probably won’t need a Terminal. But if you’re a developer, it’s hard to get away from using a CLI. There are different ways to open a Terminal command line. Terminal (Terminal.app) is the terminal emulator included in the macOS operating system by Apple. Terminal originated in NeXTSTEP and OPENSTEP, the predecessor operating systems of macOS. As a terminal emulator, the application provides text-based access to the operating system, in contrast to the mostly graphical nature of the user experience of macOS, by providing a command-line interface. Ericom Terminal Emulator software for Mac OS X supports TN3270, TN5250 among 35 types of emulators. SSL, SSH, secure terminal emulation and small footprint. Download 30-day FREE Trial. What is Terminal? Apple's Terminal app is a direct interface to OS X's bash shell — part of its UNIX underpinnings. When you open it, Terminal presents you with a white text screen, logged in with your OS X user account by default.
I am spending a lot of time on the command line for the daily development work. I decided to install iTerm2 terminal as an alternative terminal for Mac OS because the default terminal app does not offer rich and powerful features to make my development life easier. So I decided to install advanced alternative terminal to replace Mac OS default terminal.
Before you install iTerm2, please refer its features on their website.
If you happy it’s features and power, you can download the iTerm2 from the following link. Alternatively, you can use Homebrew package manager to install this package.
Install iTerm2 terminal
After download iTerm2 installation file, simply drag and drop into the Applications folder to install iterm2 terminal app. Now you can launch iTerm, through the Launchpad for verifying the installation.
Alternatively, you can install iTerms2 via Homebrew package manager. Once you install the package using Homebrew, you will be able to launch iTerm2 via Mac Launchpad.
When you open iTerm2, it’s looks and feel not that pretty impressed by the first look. You need to follow few more steps to get the look you preferred. You can completely change its looks and feel by customizing default features.
Let’s just quickly change some preferences.
Remove computer name and username from the terminal’s bash prompt
Open iTerms2 “Preferences” configurations box. Then click on “Profiles” tab and select “General” tab.
iTerm2 -> Preferences ->Profiles -> General
Add following text under “Send text at start:” text input.
Close the “Preferences” box and reopen iTerm2 terminal and you will be able to see bash prompt without the computer name and username.
Change default colour theme and fonts
You can download more colour themes to install iterm2 terminal from this web site. http://iterm2colorschemes.com/
Download the zip file and unzip it for the preparation of the next step. Now open the “Preferences” settings window.
You can create a different profile other than Default if you wish to do so. I created a new profile for adding custom settings to the iTerm2.
Open iTerms2 “Preferences” configurations box. Then click on “Profiles” tab and select “Colours” tab.
iTerm2 -> Preferences ->Profiles -> Colours
Now click on “Colour Preset” drop-down and click on “Import” option. Navigate to the “schemes” folder previously unzipped colour profile folder. Then select your preferred colour themes and selected colour themes will be added to the “Colour Preset” drop-down after installing.
Now reopen iTerms terminal and see the effect of the new colour theme.
Once I customize iTerm2 colour theme still I did not see expected nicer interface. I decided to install Oh-My-Zsh to add more features.
Before install Oh-My-Zsh, you need to remove the previously modified text input in the iTerm2 preferences.
Because of Oh-My-Zsh, follow the different approach to remove the user@your_machine name from your bash prompt.
Oh-My-Zsh is an open source, the community-driven framework for managing your ZSH configuration. It comes bundled with a ton of helpful functions, helpers, plugins, themes,
Install Oh-My-Zsh
It’s a good idea to backup your existing ~/.zshrc file before installing Oh-My-Zsh.
Now you can use the following command on your terminal to install Oh-My-Zsh. You will be able to find more details on their website.
Now you almost have better terminal compared to default one. I decided to use “Agnoster” theme with the Oh-My-Zsh.
You can find many available themes for Oh-My-Zsh here. Before you enable “Agnoster” theme, you need to install Powerline fonts.
After installation completed edit ~/.zshrc and set ZSH_THEME=”agnoster”
After enabling “Agnoster” theme, you may be able to see broken fonts on the iTerm2, follow this GIT issue for fixing this fonts issue.
Users need to set both the Regular font and the Non-ASCII Font in “iTerm > Preferences > Profiles > Text” to use a patched font.
Now you may need to remove user@your_machine name from your bash prompt. Add following lines to your “.zshrc” configuration file and restart your iTerm2 terminal.
After you done all the above customizations, you can find your iTerm2terminall as following.
How to enable packages on Oh-My-Zsh
Oh-My-Zsh by default comes with lots of plugins to take advantage of. You can take a look in the plugins directory to see what’s currently available.
Once you spot a plugin (or several) that you’d like to use with Oh-My-Zsh, you’ll need to enable them in the .zshrc file.
I have enabled following plugins in my configuration file.
How to upgrade Oh-My-Zsh
If you need to upgrade you just run following command on your terminal.

I hope you will enjoy the features of iTerm2 terminal and Oh-My-Zsh. Please comment your thoughts below.
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.
Curated Mac apps that keep your Mac’s performance under control. Avoid Terminal commands, avoid trouble.

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

Terminal can be used for all sorts of different tasks. Some of them can be performed in the Finder, but are quicker in Terminal. Waveshaper for macbook air. 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.
How To Use Mac Terminal
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!
