send GSP commands via script please help

[jamesps]

I would like to script some commands normally sent via the GSP. To be able to get the server's console via GSP (read/write) you need to type ^Ecf. Since I need to send this via script, how do I echo this?

I am doing something like:
./gspcommands | telnet

My "gspcommands" script holds whatever I need to pass to the GSP and here it is where I need to put the ^Ecf in an "echo" as well.

Thanks,
james

using vi:

echo "[ctrl-v (release)][ctrl-E (release)][c][f]"

keep in mind that in my above notation, anything in a pair of [] s is one keystroke

But you have to be doing much more than a simple pipe, you need to use something like expect to read the prompts coming back from GSP otherwise, command timing will be way off and your command most probably will not work.

expect can be obtained from:

just search for expect with their built in search box

Mel, thank you very much for your reply. That is a great help. You are right, the GSP response messages can cause some delay issues which can ruin the whole automated process. Is there a way to "read" the GSP answer in the script? Right now my script "sleeps" for the amount of time necessary and the entire process relies on that. That's the most "efficient" way I could come up so far :)
Can I send CRs (Enter's) using the same method?

Thanks again!

Sorry I just saw the expect line at the end. I am downloading it right now. Thanks!

carriage return is ^M character. In a vi session ctrl-v followed by ctrl-m, iserts a character in a command sequence.

I 'll start working on it right away. "expect" looks like the tool I needed to accomplish my task. Mel, thanks again for your replies!
