Display background running process on shell prompt

Hello,

I was wondering if it is possible in HP-uX to take a process that is running in the background, such as being run by CRON, and bring it to your current shell prompt. In other words, say I have a process called "job1" schedule to run at 12PM, and at 1PM I want to see it on my terminal session, can I bring it to my session and interact with it?

Thanks

if you are referring to job control available in csh, ksh, bash then the answer is no.

If your cron job can at 1 PM open the terminal you are at for input / output then yes

Thank you for the response,

When you say open the terminal, what exactly do you mean?

What I am trying to accomplish is this.. Say I schedule a program to run, but there is an error and we need to access it to fix it, how can I access the program to resolve the issue?

Thanks

Each user when he / she logs in the system assign a terminal device to him / her. You may find it by running the command tty

Now, if you are using telnet or ssh or X windows to login then the device name or the terminal name will be dynamic. But if you login from a console or a terminal that is directly connected then the device name will not change. In such a case, the application can use this device name to send output to it (including errors) and receive input from it. This requires a change in the program to do so.

How do you get the errors from this application?

So you are saying that cron can launch a job and direct the output to a specific terminal?

The application is a BASIC compiler that runs on HPUX ,, so the programs are interactive in the sense that they can be stopped and edited, etc, and continue.. if an error occurs on  a line in the program, it halts and sends an error email alert...

Thanks
