interacting with prompt

quarry_06 · 08-02-2005, 06:57 PM

hi
I have a program which basically opens a new prompt, say like gnuplot would. now I want to be able to send commands to that prompt and retrieve the output and write it to a file.

anyone a suggestion on how to do that?

You'll be looking at script to record the session, and
expect for interaction.

Sorry, I don't understand. looking at What script? recording is ok, but I need to send multiple commands to this prompt.

I guess I haven't explained very well.
I call gnuplot from a shell script. then I want to type into the gnuplot prompt, but from withing my shell script.

thanks

That's where expect comes in ...

It allows you to script interactive sessions.

P.S.: Could you please a) shorten your sig and b) stick
with English? Thanks.

i still don't understand your expect, but I found what I was looking for.
It is called a "here" function
and goes like this

gnuplot
<<**
do
whatever
you
want
to
do
**

can you still explain what your explain does/how it works?

and hey, I would love it if other users had sigs in other languages, so I could learn something new !

anyway thanks

I don't know how GNU Plot works ... here documents are
going to be fine for one-of activities. If you for example
have something that will ask something, expect input, do
some more, then ask something new expect is the tool
for you. ...

Good for you :) ... however, it would be a bit
much to ask of mods to learn all possible lingos
on the boards to make sure the contents is OK ;}
