It’s essentially an application that gives you access to the inner workings of a Mac. You can use it to make changes to the operating system which you otherwise can’t from the graphical user interface (GUI). Mac’s Command Line Interface (CLI) isn’t meant to be used by a casual user. That’s why its interface isn’t very user-friendly and can be hard to understand, especially if you don’t have any technical knowledge. Terminal is rooted in Unix, the core operating system on which both Mac and Linux are built. The latter has a similar command line tool that lets you execute various commands. Learning how to run Terminal in the Apple operating system is a straightforward process and we’ve explained it below. How to open Terminal on macOS Before you begin to write commands in Terminal Mac, you need to know how to open the app first. There are several ways to access Terminal. Which method you should use depends on your requirements and personal preferences. Here are some of the most common ways to open Terminal on macOS: 1. How to open Command Line on Mac via the Dock The Dock panel usually has a shortcut which takes you to all your applications. In more recent versions of macOS, this shortcut is called “Launchpad.” In the list of applications, find and open the “Utilities” folder and you’ll find the Terminal app inside it. Double-click on it to open it. Note that on some versions of macOS, the Terminal app would be located in the “Other” folder, which you can find after opening Launchpad. 2. Opening Terminal through Finder Open the Finder app (it’s always on the extreme left in the Dock). Click on Applications in the sidebar. In the list of programs that open, find the “Utilities” folder and double-click on it. Now search for the Terminal app and double-click on it to open it. 3. Opening Terminal on Mac through Spotlight search bar To open the Spotlight search bar, press the Command + Space bar keys simultaneously. In the small window that pops up, enter the word “Terminal.” After typing, the Mac console for commands will come up automatically. Click on it to open 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 between multiple tabs. How to run a command on Mac? The command line begins with the name of the computer, followed by the name of the current directory – by default, the user’s home directory opens, which is denoted by ~ (tilde) on Unix systems. This is followed by the username followed by the $ sign – an invitation to run commands on Mac. All commands are entered after the $ sign and are written in bash language. Now that you know how to use Terminal on Mac, you’re ready to start executing commands! Terminal Tricks to Know There are tons of things the macOS Terminal can do. From moving a large number of files to changing preferences that we couldn’t even imagine. To demonstrate what Terminal can do, we have put together 14 excellent tips and tricks that you might find useful. Here are some of the most common Terminal codes for Mac: 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 com.apple.finder 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 think that there’s something hidden inside it, then you can force Terminal to open it, despite other applications failing to do so. Here’s the command you need to use: cat ~/path/to/file Just keep in mind that if you try to open a photo or any other non-text document, you’ll 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 com.apple.screencapture type jpg && killall SystemUIServer 5. Disable shadows in screenshots If you tend to take a lot of screenshots and don’t want any extra effects on them, you can use Terminal to turn off the drop shadow effect, leaving only the window itself in the screenshot. Here’s the command for it: defaults write com.apple.screencapture disable-shadow -bool TRUE && killall SystemUIServer 6. New names for screenshots Not happy with the boring and inconvenient “Screenshot date-time” naming format? Here’s a command that you can use to replace the word “Screenshot” with something better: defaults write com.apple.screencapture name "New name" && killall SystemUIServer If you want to revert the settings and get the original naming format back, use the following command: defaults delete com.apple.screencapture 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 com.apple.screencapture location ~/your/location/here && killall SystemUIServer 8. How long has my Mac been on? Can’t remember how long it has been since you rebooted your computer? You can check this using the following command in the Terminal: uptime 9. Disable sleep mode Sometimes it becomes necessary to keep your Mac awake, like when you’re creating a backup. While using Mac Terminal, you can disable hibernation on your Mac by typing: caffeinate Now your Mac won’t fall asleep no matter what happens. Tip: You can specify the time (in seconds) after which your Mac will automatically go to sleep if it’s inactive. Here’s how you can input the command along with specified time in the command prompt: caffeinate -u -t 5400 10. Start auto-restart when the Mac completely freezes While Mac computers are generally reliable, sometimes they tend to freeze for no reason at all and a forced reboot is the only solution. The following command forces the OS to reboot if it notices that the system isn’t 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 when you’re working, the type-to-talk command primarily exists for entertainment purposes. When you type the say command, your Mac will repeat anything you type afterwards. Your Mac has over 100 voices you can choose from. By adding a name to the command say -v name you can change the voice it uses to repeat the text you enter into 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 left-hand menu list; Open the System Voice drop-down menu; Select Customize; Browse the voice options available and pick the ones you like the most. Keep in mind that while the say command recognizes periods and commas, you have to type everything into a single line because the Return key executes any command you type. We recommend typing longer paragraphs of speech in a text document first, and then copying and pasting them into Terminal. 13. Repeat characters by holding down a single key Those who use both Windows and macOS will notice slight differences in the keyboard functions of each operating system. It can take some time to adapt to the different keystroke responses of a Mac. One of the most noticeable differences is when you press and hold 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. Customize a Login Window Message Whether you’re using your Mac for productivity or entertainment , it’s a great feeling when you customize it to make it a bit more personal. Using Terminal, you can create your own message for the login window of your Mac and this customization can be extended across multiple systems, whether at work or an educational setting. The command line is: sudo defaults write /Library/Preferences/com.apple.loginwindow LoginwindowText "Your message here" Make sure you log out of your account or restart your Mac to start seeing the greeting message when you log back in. This message will then appear every single time you log into your computer. If you want to change the message seasonally or remove it altogether, just use the command below: sudo defaults delete /Library/Preferences/com.apple.loginwindow LoginwindowText Using Terminal tricks is one way to get more computer savvy, have fun with the native features of macOS, and customize your computer according to your preferences. Here’s a cheat sheet that lists some of the most commonly used Terminal commands and shortcuts. Mac Terminal Commands List to improve productivity Here are some important Mac command line commands that you can use to improve your productivity and make your workflow smoother: Shortcuts To save time, you can take advantage of keyboard shortcuts while using Mac Terminal.

Here are some of these commands: Command Action / Root directory . Current working directory .. Parent of the current working directory ~ Home folder for the logged-in user sudo Run current command using super user security privileges nano Open the Terminal editor open Open a specified file -h Open help for a specific command man Access the help manual for a specific command exit End your current shell session Change Directory There are various commands you can use to copy, move, delete directories, and perform other similar actions. Here are some of them: Command Action cd Navigate from one directory to another cd Change the directory to a new specified folder cd ~ Navigate to home directory of logged-in user cd / Navigate to the root directory cd - Navigate to the last directory you opened pwd Show the current working directory cd .. Navigate up to the parent of the current directory cd ../.. Navigate up two parent directors from the current cp -r To copy directories mv To move directories rm -r To delete directories List Directory Contents You can view the contents of a directory in the form of a list using the following command: ls There are plenty of things you can do with the ls command. For example: Command Action ls Show all file and subdirectory names in the current directory ls -C Show listing in forced multi-column ls -a List all entries including . and .. directories ls -1 Show file list in single-entry per line format ls -F Organize output with a slash / after directory paths, asterisk * after programs and scripts, at @ after symbolic links ls -S Organize files and entries by size ls -l Long-form list with: file owner, group name, mode, date, time, pathnames and more ls -l / Symbolic link list of the file system from the root ls -lt Files listed by time, with most recently modified first ls -lh Long-form list organized by human-readable file size in KB, MB or GB ls -lo List organized by file names with file size, owner, and any flags ls -la Detailed list of a directory contents including any hidden files File Size and Disk Space There are some Terminal commands that will show you the size of files and how much space they take up on your Mac. Here are some of them: Command Action du List showing the usage of every subdirectory and its contents df -h Display your system free disk space df -H Display your system free disk space in powers of 1,000 instead of 1,024 du -sh Display a human-readable output of a directory files du -s List entries for specific files du -sk * | sort -nr Display all files and folders with total size including subfolders in KB; use sm instead of sk to get directory size in MB du -k To view the size of file in kilobytes To view the size in megabytes and gigabytes, replace the -k with -m and -g, respectively. File and Directory Management File and directory management commands will assist you in working with directories in the Terminal. For example, you can use the pwd command to see the name of the current working directory. Command Action mkdir Generate a new folder with name mkdir -p / Make several folders at once, without nesting mkdir " " Generate a folder with a space in the file name rmdir Delete an empty folder; doesn’t work for folders with contents rm -R Delete both a folder and its contents touch Generate new file without specifying an extension cp Duplicate a file to a specified folder cp Duplicate a file to the current folder in use cp ~/ / Duplicate and rename a file to a specified folder cp -R " " Duplicate a folder to a new, specified folder when there are spaces in the filename cp -i Provide a warning prompt before copying a file regarding overwrite cp /Users/ Duplicate multiple files to a single folder cp To copy a file to a directory ditto -V Duplicate a folder contents to a new specified folder V prints a line status for all the copied files rm Delete permanently a file: be cautious when using this command rm -i Ask for confirmation before deleting a file rm -f Remove forcibly a files without needing confirmation rm Delete several files at once without needing confirmation mv Move a file location and rename it mv Relocate a file to a new folder; allows possible overwrite of existing files mv -i Add an optional -i flag warning before file overwrites mv *.png ~/ Relocate files with PNG extension from current folder to a new one Note that if the file doesn’t exist, your Mac will automatically create it for you. Command History Can’t remember the last command you executed? Don’t worry, the Mac Terminal lets you see a history of all the commands you’ve executed with the following command: history Command Action Ctrl + R Perform a search in prior commands history n Display prior typed commands; add a value to n to limit the displayed items ! Execute last typed common that begins with a value !! Execute whatever command was typed last Permissions Permissions commands allow you to see and change permissions for specific files and directories, which is important if you want to maintain the security of your data. You can use these commands to change the ownership of files. Command Action ls -ld Show a home directory default permissions ls -ld Show a folder permissions for read, write and access chmod 755 Revise a file permission to 755 chmod -R 600 Revise both a folder and its contents permission to 600 chown : Change a file ownership to a new user and group; the addition of -R will include the folder contents in the change chmod To change the read and write permissions for a file The field is a three-digit number that indicates owner, group, and everyone else’s permissions. Read is represented by the number 4, write by the number 2, and execute by the number 1. To give no permission, you have to write the number 0. Each digit in the field is calculated by adding up the values for the specific permissions. Take the following command for example: chmod 600 This command will give the owner read (4) and write (2) permissions, but no execute (0) permissions (4+2+06). The group and everyone else will have no permission since the second and third digits are both 0. Processes As the name indicates, the processes commands help you understand what processes are currently running and perform some other useful operations. There are three main commands: view, find, and quit. Command Action ps -ax Display currently running processes; a display processes from all users; x display processes disconnected with the Terminal ps -aux Display processes with %cpu, %mem, page in, PID and command top Show relevant live information about running processes top -ocpu -s 5 Get an update every 5 seconds of processes sorted by CPU usage top -o rsize Display a list of processes sorted by memory usage kill PID Quit all processes with the ID PID; view PID as a column in the Activity Monitor ps -ax | grep Locate processes by name or PID Network There are several network commands you can use on your Mac. Here are some of the most basic ones: Command Action ping Ping the display status and host whois Show the whois for a specified domain curl -O Download a selected file with HTTP, HTTPS or FTP ssh @ Create a SSH connection from a specified host with a user designated with username scp @ :/remote/path Copy a specified file to a remote host arp -a Display a list of your local network devices with IP and MAC addresses ifconfig en0 Display your own device IP and MAC address traceroute See the path and hops when packets traverse from your device to a designated address Homebrew Homebrew is a package manager on macOS. In essence, it installs, updates, and manages software packages on your computer. Here are some of the most common Homebrew commands for Mac Terminal: Command Action brew doctor Review the homebrew for potential issues brew help Display a list of useful formula and cask commands for homebrew brew install | Install a homebrew formula or cask brew uninstall | Uninstall a homebrew formula or cask brew list --formula Display a list of the installed formula and nothing else brew list --cask Display a list of the installed cask and nothing else brew deps | Display a list of a formula or cask dependencies brew search text|/regex/ Use regex to search for formula or cask brew upgrade | Perform upgrades for the specified formula or cask brew outdated | Perform a search for out-of-date formula or cask brew outdated --formula Perform a search for an outdated formula alone brew outdated --cask Perform a search for an outdated cask alone brew pin Add a pin to a formula to prevent an upgrade brew unpin Unpin formula to upgrade a package brew cleanup Remove stale lock files and outdated packages for all formula and cask Environment Variable or Path Environment variables refer to information such as the current user’s home directory, the username of the current logged-in user, the language of the computer, and more, type: Command Action printenv Show a list of the environment variables currently set and which are in current use echo "Hello" Specify something for the terminal to print and display echo $PATH Evaluate a PATH variable value that storing a list of directories and executables files echo $PATH >path.txt Export the current PATH directory to a text file export PATH$PATH:absolute/path to/program/ Restrict a program execution via terminal to your current session for regularly used programs; add the PATH to the shell configuration Search Search commands help you locate specific files and contents within directories. Use the following commands: Command Action find -name " " Locate all specified files by name within a certain directory ; use * to search for parts of filenames grep " " Display an output of every occurrence of specified within a certain ; use -i to ignore case sensitivity grep -rl " " Locate any files containing specified within a certain Output A forwarding output command lets you take the output of one command and extend it to the second command where it’s used as an input. Here’s how you write it in the macOS Terminal: Command Action cat Output all content of a specified less Use the less command to support pagination and other features when outputting contents of a specified head Output only the first ten lines of a specified >> Add the output of a specified to the > Specify the output of into a certain | Specify the output from to The list shared here isn’t exhaustive and there are many more Terminal commands that you can use to give your productivity a boost.
