Incorporate Ctrl-Z into program

[chuair]

I have a program with a set of predefined command that I will enter. A so called editor will apprear next that requires me to enter some text and then I am required to press Ctrl-Z to save and end the program. How do I incorporate the Ctrl-Z into my program so that I don't have to do it manually?

Something like this ?
echo "\032\c"

Hope This Helps, PH.

Thanks for the prompt reply. The problem now is that after executing the command of my program by script, it sort of like hangs there, waiting for the text to be entered and the Ctrl-Z to be entered. How do I programmatically do it?

As you said nothing about your script code, just a guess:
echo "\
line1 of text
line2 of text
\032\c" | yourProgram

Sorry. The command for my program is like
exex -c "ZC:11:1:4:1,DEM:4;" -n MC_C_11 which is executed in UNIX environment. It will then go to something like vi mode where I will key in some text and press Ctrl-Z to save and exit the program, which will bring me back to the UNIX Shell prompt.

\032\c" | exex -c "ZC:11:1:4:1,DEM:4;" -n MC_C_11

Doesn't seems to work leh.It will just hangs there and the cursor keeps blinking.....

Seems the exex program reads /dev/tty instead of the standard input.
You may try using expect.

Expect?What's that?How do I do it? And is the /c the equivalent of Ctrl-Z?

Have you thought about using a different editor or possibly not using an editor at all?

Hahahahahahahahaha....................Nope. We are trying to implement something into the system and it's one of the requirements that we have to go through.............I guess if there's no other way, then I just have to do it manually, keying in one by one..... :-(
