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.

Send keypresses to an X application

This is a (last resort) way to automate applications that provide no other ways for automation, it would send 'Hello world' to the currently active window. See the manpage (and the -text and -window entries) for how to send special characters and target specific windows.

An example:

Using xwininfo, I get the id of my XPlanet background window:

alanceil@kvirasim:19:51:0:~> xwininfo

xwininfo: Please select the window about which you

would like information by clicking the

mouse in that window.

xwininfo: Window id: 0x3600001 "Xplanet 1.2.0"

Absolute upper-left X: 0

(..etc..)

Now I use xvkbd to tell it to close itself:

xvkbd -xsendevent -window 0x3600001 -text "Q"

Obviously, the best way is to put these commands in a shellscript - just make sure to include a short sleep (sleep .1 should suffice) after each xvkbd call, or some programs will become confused.

Alternatives

There are 6 alternatives - vote for the best!
