Thanks everyone

'expect' appears to be the thing im looking for. However I cant figure out
what the sleep/wait/exit should be at the end of the script for this
'glmark' program as it spawns a child (I think) window after the small
amount of input. With an 'exit' it stops/kills the program before child has
a chance to display, with a 'wait' does the same thing, with a 'sleep 20'
nothing happens for 20 seconds then same result as the first two.

script:
#!/usr/bin/expect -f

spawn /home/username/GLMark-0.5.2.1/glmark

expect "Enter screen width: "

send "400\r"

expect "Enter screen height: "

send "300\r"

expect "Enter screen bpp: "

send "16\r"

expect "Enter '1' for fullscreen '0' for windowed:"

send "0\r"

sleep 20 # or wait?

Anyway, the discussion is just trivial now - theres a glmark2 package that
runs the way I want by default without input so thats what Ill use. Still,
would be interesting to know the answer.

cheers
