It will happily go on running in the background, even ifyou're running an interactive program like Vim. Grabbinga screenshot without XDifficulty: Easy Application: Shell There are plenty of screen-capture tools, but a lot of them arebased on X. This leads to a problem when running an X applicationwould interfere with the application you wanted to grab - perhaps agame or even a Linux installer. If you use the venerable ImageMagickimport command though, you can grab from an X session via theconsole. Simply go to a virtual terminal (Ctrl+Alt+F1 for example)and enter the following: chvt 7; sleep 2; import -display :0.0 -window root sshot1.png; chvt 1;The chvt command changes the virtual terminal, and the sleep commandgives it a while to redraw the screen. The import command thencaptures the whole display and saves it to a file before the finalchvt command sticks you back in the virtual terminal again. Make sureyou type the whole command on one line. This can even work on Linux installers, many of which leave aconsole running in the background - just load up a floppy/CD withimport and the few libraries it requires for a first-raterun-anywhere screen grabber. Accessyour programs remotelyDifficulty: Easy Application: X If you would like to lie in bed with your Linux laptop and accessyour applications from your Windows machine, you can do this withSSH. You first need to enable the following setting in/etc/ssh/sshd_config: X11Forwarding yesWe can now run The GIMP on 192.168.0.2 with: ssh -X 192.168.0.2 gimpMaking man pages usefulDifficulty: Easy Application: man If you are looking for some help on a particular subject orcommand, man pages are a good place to start. You normally access aman page with man , but you can also search the manpage descriptions for a particular keyword. As an example, search forman pages that discuss logins: man -k loginWhen you access a man page, you can also use the forward slash key tosearch for a particular word within the man page itself. Simply press/ on your keyboard and then type in the search term. Talk to yourdoctor!Difficulty: Easy Application: Emacs To say that Emacs is just a text editor is like saying that aTriumph is just a motorcycle, or the World Cup is just somefour-yearly football event. True, but simplified juuuust a littlebit. An example? Open the editor, press the Esc key followed by X andthen enter in doctor: you will be engaged in a surreal conversationby an imaginary and underskilled psychotherapist. And if you want towaste your time in a better way Esc-X tetriswill transform your 'editor' into the old favourite arcade game. Does the madness stop there? No! Check out your distro's packagelist to see what else they've bundled for Emacs: here at LXF Towerswe've got chess, Perl integration, IRC chat, French translation, HTMLconversion, a Java development environment, smart compilation, andeven something called a "semantic bovinator". We reallyhaven't the first clue what that last one does, but
