The script is on github and was written to work on Mac OS. I will be running it on Linux, which takes some modifications to make work and I will show you how to do that. Download the code from https://github.com/dreamhost/screencaps
The code is written in Python and requires the boto library to connect to DreamObjects. You can install boto by opening the Terminal and typing:
pip install boto
If you get an error typing the message above, -bash: pip: command not found then you do not have pip installed on your system. You can type this in the Terminal instead to install it on Ubuntu (it will require an admin password):
sudo apt-get install python-boto
You will also need a program to take the screenshot. I use
install scrot on Ubuntu run the command below.
sudo apt-get install scrot
If you don’t have one already, create a folder called bin in your home directory and copy dhdo-screencap.py file into it. Open dhdo-screencap.py with a text editor and paste in your DreamObjects Access Key, Secret Key and bucket name (ensure each of these are surrounded by single quotes). If you are running the script on Linux you will need to change some things, such as set the program that will take the screenshot
result = subprocess.call(['screencapture', '-i', f.name])
result = subprocess.call(['scrot', f.name])
The above code is equivalent to running the following command in a shell.
Save and close it. Now you can run the script and it will take a screenshot and upload it to the bucket you specified. It is a good idea to assign this to a keyboard shortcut. How you do this depends on what desktop environment or window manager you use. Google for instructions that are specific to what you are using.
