Using GIMP to draw a rectangle

Posted on July 28, 2015 by swk

GIMP is not your typical program for drawing, but is is the only thing related to graphics that is installed on my linux. So I have this screenshot and I want to draw a red rectangle around the part that needs to be clicked. This is how:

Open your graphic file with GIMP.
Use the "Rectangle Select Tool" and mark the place where you want your rectangle to be.
Select the color you want to draw the rectangle in as foreground color (in my case that would be red).
In the menu "Edit" choose "Stroke selection".
In the dialogue that comes up, choose "Stroke line" with "solid colour" (it will take the current foreground color), you can adjust the width and if you open up "Line style" you can do more things (e.g., rounded edges).
Click "Stroke" and voila!

Executing a command on a remote server

This is probably a very old hat for Linux-savy people. You can use ssh to execute commands on a remote server, just pass them on as an additional argument:

ssh me@my.server.de "cd bla ; ls ; python test.py "

I use double quotes (“) istead of single quotes (‘) to interpret variables. Different commands are separated with semicolon (;). You can use any command you like, but for some reason when I call some GUI I don’t get the output on the command line until the window is closed.
