Hi,

I am executing a shell script using java program on unix platform.
I am using Runtime.exec(shell_script_name) method to execute it.
A shell script uses prstat command & it gives well formated output to my java program.
But, the problem is that the prstat command doesn't get killed by unix os.
so that , when ever I execute the script each time a new instance of prstat is seen as a new process using ps -fu command. & this prstat process seen even when java program is stopped.

please, help me so that prstat command execution should get stopped just after script execution finished.

Thanks

Does your shell script launch "prstat" in the background?

If not, have you tried to invoke Process.destroy() after you've got necessary outout?

BTW, what happens if you invoke the same shell script manually?
