Admittedly, I'd never have thought of this without the earlier examples, but here's one that you can execute from your workstation to just display the image from another, without separately doing a file transfer, etc. By the way, I hear a loud beep coming from the other room, so I guess it's not too stealthy :-D


There are 2 alternatives - vote for the best!

Of course it requires import command, from imagemagick tools, but it's simpler to type, and imagemagick is usefull anyway.

DISPLAY=":0.0" import -window root screenshot.png

The `export` is unnecessary if it's only applicable to the one command.

DISPLAY=":0.0"; export DISPLAY; import -window root gotya.png

Functions: export

Say if you're logged into a remote system via ssh and this system has an x window system, but yet you still want a screen shot of what's going on graphically. This will do it for you. :-)

export DISPLAY=":0.0" && import -window root screenshot.png

User: fraktil
Functions: export

Like the given command, but combines _DISPLAY=":0.0"_ with _export DISPLAY_ to get _export DISPLAY=":0.0"_ and only imports if DISPLAY is set successfully.

Know a better way?

If you can do better, submit your command here.

There was a web app that takes screenshots of your webpage running on different browsers/systems and packages it for you in a zip so that you can analyse.
