One of the easier, and most useful, commands to use in conjunction. Open or quit Terminal on Mac. Each window in Terminal represents an instance of a shell process.

Using screen as a serial terminal on Mac OS X

If you develop on an Apple and find yourself doing any sort of device or embedded development, you will quickly find the need for a serial terminal on Mac. There are a few software apps out there, but I find it much simpler to simply use the terminal application “screen”.
This works well particularly if you have an RS-232 serial to USB converter.
The first thing to do is determine which device you want to connect to.

Once you’ve determined which device you would like to use, you can execute the SCREEN command to start the serial terminal session on your Mac. Remember to specify the speed (baud rate) after the device name.

Once you’ve connected, you can use the terminal as you normally would.
To exit (and close the screen gracefully) press:

Screen will then prompt you to quit and kill all of your windows. Press “y” and you’ll be back to your shell terminal.
This method works equally well if you want to connect to a serial bluetooth device. You must simply make sure that the bluetooth device is paired and active. Then you will be able to see the device in the list of devices. Once you’ve connected to the serial bluetooth device with screen, the connection will be held active for the length of your session.
I’ve used this method to connect to the sparkfun Bluetooth Mate Gold. It simply appears as a serial stream that you can communicate with exactly as you would with any other serial device.

When people heard the word Mac Terminal, they get scared thinking that using Terminal is very hard. But the truth is quite the opposite. Once you get a hold of Terminal commands, it will become easy for you to carry out even the complex task on Mac easily. So, in this article, you will learn how to open and use Terminal on Mac.

Part 1. Basics of Mac Terminal:

Just like the Windows command line, Mac Terminal is the command-line system that helps the users to take control of the operating system and make changes in it. The best thing you can do to learn using Terminal is to start using it. The most important thing you need to learn is commands.

All you need to do is to type the command and hit Return to execute it. Every command has three components, the command itself, an argument, and an option. The command is self-explanatory; the argument tells the command the source where it should operate and the options work as a modifier for the output.

For example, if you want to move a file from one folder to another, the command used will be- mv. Then type the location where the file exists and add file name and location where you want to move it.

While you are using the Mac Terminal, you should know about the basic rules too.

• Every single character matters in the terminal command, even spaces, and commas.
• You can't use a mouse or Trackpad inside the Terminal. Therefore, you'll have to navigate using the arrow keys, and Return key.
• Commands are executed inside a location, so if you don't specify a location in the command, it is automatically set to the recent or previously specified location.

Part 2. Basic Commands and Functions of Terminal:

The macOS terminal is a tool that requires skills and intelligence to learn. You will have to pay attention to even the smallest detail to ensure that you don't make mistakes. From learning how to open the file via Mac terminal to terminal deletion, every single command matters. Here are some basic commands that you need to understand if you want to improve your terminal knowledge.

• ls- list the contents of a particular directory
• cd-change to another directory

• defaults write com.apple.finder AppleShowAllFiles -bool TRUE to show hidden files.

Part 4. How to Use Terminal Commands on Mac:

Here is a list of some common commands used in Terminal. These commands will provide you a short and precise method to carry out the task.

1: Delete Files Using Terminal:

Removing files using the terminal is a much more convenient method to delete files and folders permanently. You can delete multiple files quickly and efficiently. The terminal can also be used to delete files from Trash.

To delete files from Mac, the rm command is used. As you launch the terminal and type cd ~/Desktop to get to the desktop directory, find the file that you want to delete and enter its name. For example, if you want to delete MyFile.rtf, then you will pass the command as- rm MyFile.rtf and the file will be gone forever. To delete multiple files, just leave space between the file names and hit the Return key and Terminal will take care of the rest.

2: Open Finder from Terminal:

Some people would say why they need to learn how to open a finder from the terminal. Well, it comes in handy when the OS is not working properly or you have to find the hidden files. For this, the command passed will contain the following components:

• Controls: Mac-Admin is the name of the system and is separated by the colon. The next section, ~ or / minas that you in the user's root or home folder. And admin$ is the username.
• PWD: It is the Print Working Directory that shows you the path to the folder in which you are currently located. When you pass this command, it will give results like /Users/admin. The /Users is the user folder present in the root folder of the disk and /Users/admin is the current user folder which is present inside the Users folder.
• CD: It means change directory or folder.
• OPEN: To open Finder using the Terminal, you will have to type this command.

If you want to view hidden files and folder in the macOS, you'll have to use the show hidden files Mac terminal command. Write the command as-

$ defaults write com.apple.finderAppleShowAllFiles –bool TRUE

$ killall Finder

As you hit Enter, the command will execute and you will see a lot of files in the Finder window that you can't see because of privacy. To reverse the process, you just have to change TRUE into FALSE and the files will become hidden again.

4: Empty Trash Using Terminal:

As we discussed above, Terminal can be used to empty trash too. To empty trash using a Mac terminal, you will have to follow some different steps.

Step 1: Type the command as sudo rm –R without pressing the Enter key and control-click on the Trash icon to open it.

Step 2: This will open the Trash folder. Select all the files that you want to delete and drag them to the terminal window. Then press the Enter key and provide the admin password.

When you enter the password, you won't see any change in the Terminal screen. After that, press the Enter key again and the trash files will be deleted from your Mac.

5: Change Folder Permissions:

It is possible to change the file permission of a file and folder using the Finder, but Terminal gives you better control and flexibility. Permissions are assigned considering user, Group, or others and have attributes such as read, write, and execute. To change permissions, you will have to use the chmod command. It runs in two modes, i.e. absolute and symbolic. For beginners, it is better if they stick to the symbolic mode as Absolute mode is for advanced users. This is how you can change folder permissions using the Mac terminal.

For a file or folder, you will have to specify the category (user, group, others, or all three), type of operation (e.g. add permissions, delete permissions, clear permission, or use the default), and the permission itself, i.e. read, write, or execute. Suppose you have a folder which has permission like- drwxr-xr-x and it means:

• User- rwx(read, write, or execute)
• Group- r-x(read and execute)
• Others r-x (read and execute)

Type cd and drag the folder whose permissions you want to change. This way, you won't have to specify the location of the folder as it will copy the path.

Type the command ls –l in the terminal to reveal all the subfiles, sub-folders, and their permissions. Now to change the permission of any folder or file, type- chmod 01234567 and the path file folder such as type chmod 755/bin which gives the bin folder Read/Write/Execute permission to the folder.

6: Repair Disk:

To repair disk using a Mac terminal, you will have to follow a simple procedure. The command to repair disk is direct- diskutil repairvolume /. Before you get to this, it is important that you determine the repair your disk needs.

You simply have to type the command with the location of directed at other volumes such as- diskutil repairvolume /Volumes/ExternalBackups/ and hit the Return key to execute the command. The repair disk command will resolve all the issues on the disk.
