Wait for an already launched program to stop before starting a new command.

If you really _must_ use a loop, this is better than parsing the output of 'ps':

PID=$! ;while kill -0 $PID &>/dev/null; do sleep 1; done

kill -0 $PID returns 0 if the process still exists; otherwise 1

Wait for an already launched program to stop before starting a new command.

The '[r]' is to avoid grep from grepping itself. (interchange 'r' by the appropriate letter)

Here is an example that I use a lot (as root or halt will not work):

while (ps -ef | grep [w]get); do sleep 10; done; sleep 60; halt

I add the 'sleep 60' command just in case something went wrong; so that I have time to cancel.

Very useful if you are going to bed while downloading something and do not want your computer running all night.

xvkbd -xsendevent -text "Hello world"

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.
