Call interactive bash shell scripts

Hi Guys,

In Chef Is there any way to call interactive bash shell scripts ? If yes, How ?

I have to automate my environment so in some tasks we are running shell scripts interactively, so how can we achieve this through Chef ?

I did it by creating a answer script (./install_bla.sh < answer) or use Autoexpect http://www.admin-magazine.com/Articles/Automating-with-Expect-Scripts

It depends on what responses the scripts expect. If it only expects a “yes” response, the yes program may be all you need:

yes | myscript.sh

If the responses are more complicated, maybe a response file or a HERE document may help:

myscript.sh <<ENDMYSCRIPT
y
response1
response2
ENDMYSCRIPT

If the script doesn’t accept input on stdin but through some other mechanism, you might have to bring out the big guns as Nick suggested.
