UNIX for Dummies Questions & Answers

My problem is as follows:

I have to write a korn shell script which will run mutiple java applications one after one. For example,
I will execute the java application A first, after it is done I will run application B.

My question is how do I do this? How does my korn shell script know that the application A is finished before running the application B.

B can not run until A is done.

Any help is grealy appreciated. Please provide some samples.

Thanks.

When you execute the java code in the script you can get the process ID of the executing java process. You then set up a while (or similar) conditional statement to look at the process table and see when the process terminates.

There are other ways to do this. The one above is the first idea off the top of my head (using shell scripts). It would be much easier to do this using PERL or PHP or PYTHON, BTW.

You can also look at the exec command and variants and the shell command itself. There are many, many ways to do what you are wanting to do.
