Same commands work on Ubuntu, Fedora and other Linux distributions. The output might be formatted slightly differently but its all the same information.Comma. Working with Terminal. Start off by running the following command in the command line: Diskutil list. This is going to list all the mounted drives on your Mac. Once you have found the proper drive to erase, just copy its identifier so you can use it for the next command. Then pick a name and a system format type.
Using screen as a serial terminal on Mac OS X
Geek Inc.
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.
Most users use Disk Utility to erase a disk or hard drive. But some Mac users might need to erase them from the command line on Mac OS. To do that, the only thing you need is a bit of precise syntax to make sure that you are erasing the proper disk.
Here I'll show you how you can erase and format a disk using the command line.
Working with Terminal
Start off by running the following command in the command line: Diskutil list
This is going to list all the mounted drives on your Mac.
Once you have found the proper drive to erase, just copy its identifier so you can use it for the next command. Then pick a name and a system format type. This is the syntax we need: Diskutil eraseDisk FILESYSTEM DISKNAME DISKIDENTIFIER
Let’s say the disk I want to erase has “/dev/disk5s2” as its identifier and I’m going to use Mac OS Extended Journaled (JHFS+) as the system format type and name it “Empty”. The syntax is going to look like this: Diskutil eraseDisk JHFS+ Empty /dev/disk5s2

It’s important to keep in mind that if you run the eraseDisk command, the target disk is going to lose all its data, so make sure you are erasing the proper disk.

If you need different system format types, here are a few references you could use instead of JHFS+:
