Keyboard shortcuts for changing desktops in Ubuntu

4th April 2008

I am more than a little surprised that I didn't encounter these earlier: Ctrl + Alt + Left Arrow Key moves left, and Ctrl + Alt + Right Arrow Key moves right through your Ubuntu desktops or workspaces. It's always handy to be able to save on mouse work while doing this sort, so these could prove useful. I wouldn't be at all surprised if they applied to other Linux distros too.

Recalling previous commands in the Korn shell

18th May 2007

The default shell on Solaris boxes seems to be Korn and the version that I have encountered doesn't appear to allow obvious access to the command history. In the bash shell, the up and down cursor keys scroll through your command history for you, but Korn doesn't seem to allow this. Thankfully, there is another way: you can set up the editor vi as the default method for gaining access to the command history by adding the following line to the .profile file in your home directory:

set -o vi

Then, you can use the Vi (it's pronounced vee-eye, apparently) commands ESC+h and ESC+j to move up and down the list of previous commands. That, or, assuming that you have access to it, just use the bash shell anyway...
