Screen Capture Mac Os Terminal

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.

The second example below shows a screenshot of the same terminal window above, but this time with the shadow disabled. The downside with this particular example is there’s no borders showing on the window in the screenshot, so there appears to be a lot of whitespace between the top of the screenshot and this text here, even though all that. Steps capture screenshot as PDF or JPEG in Mac OS X. Open Terminal: While you are in Finder press Shift,⌘,A to open Applications and then click on Terminal. You can also open Launchpad and search for Terminal. Now in terminal run below commands to change the screen-capture format to.pdf. Defaults write com.apple.screencapture type pdf.

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

MAC has a built in feature that lets you take screenshot on your MAC.
A good time to restate that if you only want to take a screenshot of a specific window, follow this instruction: Press Command-Shift-4 on your keyboard. Press the Spacebar, the cursor will change.

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.

There is no Print Screen button on a Mac Keyboard as you may find on Windows, but there are some advanced options available that we can use to capture screens. You need to press certain key combinations in order to take a screenshot.

Here is how you can take a screenshot on a Mac OS X (like what we call print screen on Windows)

To capture complete Window

Command Key (⌘) + Shift + 3

This will take a screenshot of the entire window (just like print screen works for Windows) and you will find the screenshot on the Mac desktop.

To capture the selected portion of the screen

Command Key (⌘) + Shift + 4

When you press these combination keys a plus sign will appear with x and y to co-ordinate indicators, you can simply select the area that you want to capture, again the screenshot will be available on the Mac desktop.

To capture an Application window

Command Key (⌘) + Shift + 4 , then hit space-bar

When you press 3 combination keys a plus sign will appear, then press space-bar, a Camera icon will appear when you click your mouse button, only the active window screen will be captured, the screenshot will be saved

You would see that when you press any of the key combinations you hear a click sound and the screenshot image is stored by default on the desktop with a format Screen Shot YYYY-MM-DD at HH.MM.SS AM/PM with a .png extension (example Screen Shot 2020-08-25 at 1.17.56 pm)

If you want that the image should be copied to the Clipboard instead of being saved, you have the following key combinations to press.

To capture complete window and Save as Clipboard

Command Key (⌘) + Control(^) + Shift + 3
