Every new command is wrapped in a tweet and posted to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning, there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.

Get non-printable keycode to bind keys in applications

In exemple, screen can bind keys to switch between windows. I like to use Ctrl + Arrow to move left or right window. So I bind like this in .screenrc :

bindkey ^[OD prev # Ctl-left, prev window

bindkey ^[OC next # Ctl-right, next window

Auto export display when coming from SSH

In some case, you need to use remote gui on servers or simple machines and it's boring to see "cannot open display on ..." if you forgot to export your display. Juste add this line in .bashrc on remote machine. Dont forget to allow remote client on your local X server :

xhost +

Ultra shortcut for ssh root@

When you have to manage lot of servers, it's boring to type ssh root@myhost for each connection. Now you can type juste "s someting" and you are connected.

You can too add bash_completion script to complet with tab the name of your servers. This will be the next tips from me ;)
