Java how to run script? call other script? su to another user? make a cron?

Good morning. I am searching for "how-to"'s for some particular questions:

1. How to write a script in HP-UX 11.

2. How to schedule a script. [using cron job.]

3. How to "call" scripts from the original script.

4. How to su to another user from within a script.

This is the basics of what the script should do.
su to a user
go to a specific directory
execute a process to stop a driver,
then another process to start a driver
exit su
begin the same as above, for the next user, and so on.


[I know the gist of the steps, because I do them from command line, but I
consulted with a person who works here, and he said you can't just script
the exits all in one file, because it'll make the script quit. My idea, is that
if we could somehow have the script call other scripts, that would work,
right? I hope that you gurus can assist lil 'ol me]

I need a script that does this:

1. call a second script, that does this:

2. su to user_x
3. cd to a specific directory
4. run a specific process to stop a driver [process already made, only
user_x can run it]
5. run a specific process to start a driver [process already made, only
user_x can run it]
6. exit [to quit out of su for user_x]

7. call a third script, that does this:

8. su to user_y
9. cd to a specific directory
10. run a specific process to stop a driver [process already made, only
user_y can run it]
11. run a specific process to start a driver [process already made, only
user_y can run it]
12. exit [to quit out of su for user_y]

13. call a fourth script, that does this: (you probably know where I'm
going with this by now ...)

14. su to user_z
15. cd to a specific directory
16. run a specific process to stop a driver [process already made, only
user_z can run it]
17. run a specific process to start a driver [process already made, only
user_z can run it]
18. exit [to quit out of su for user_z]

19. end of script

20. schedule script to run every morning at 5:30 AM using cron

I had looked around the forum, and I think I could do this so far:

script name: startdriver.sh

and it calls other scripts (something like this)

startdriver1.sh && startdriver2.sh && startdriver3.sh

I hope that someone can assist me. I don't know the syntax for writing
the scripts. I know the manual commands to type in during a session, but
not the scripting.

I know that we use HP-UX, and that we use cron for scheduling jobs.

I wish that I was more help.

If you need more information prior to assisting me, please give me a
command I can run to find out that information.

[I don't normally do Unix work. I want the script so that I don't have to
manually type in the commands.]

If this forum is not the proper place for a beginner such as myself, please
direct me to the proper forum.

Thanks!

And if the second script fail the others are never called?

Why not simply have a script for each user called by root cronfile?
Then the syntax would be in the cron file:
su - <user> -c <your_users_script>

Actually, if any of the three scripts fail, the process fails.

I'm asking because I don't know how to do this.

This is what I know how to do:

su <username>
cd /path/path/path/path
driver1.stop
driver1.start
exit
su <username2>
cd /path/path/path
driver2.stop
driver2.start
exit
su <username3>
cd /path/path/path
driver3.stop
driver3.start

Are you saying that I can schedule them independently of each other?

Due to the nature of the program (drivers for some program to tie into a database), I am not sure if I can do them, except in this order.

Create a user.list file having the user.name , stop command and start command.
Code:
# cat <<eof>>user.list
user1 /path/to/user1/stop.proccess /path/to/user1/start.proccess
user2 /path/to/user2/stop.proccess /path/to/user2/start.proccess
eof

Use a loop to read from user.list and to test(echo) each command.
Code:
# while read user stop start
    do 
       echo su $user
       echo $stop
       echo $start
       echo exit
    done < user.list

The output will be:
Code:
su user1
/path/to/user1/stop.proccess
/path/to/user1/start.proccess
exit
su user2
/path/to/user2/stop.proccess
/path/to/user2/start.proccess
exit

When you have everything as you like , just remove the echo on your loop.

Success.
