Help in background process
Hi,

I have a main script(main.ksh) within which I have called another script(sub.ksh). The sub.ksh script is made to run in the background using '&'. The main.ksh script logs the information in a logfile main_ddmmyy and the sub.ksh script also logs the information in the log file sub_ddmmyy. This sub.ksh script will take long time to execute.

My problem arises here. Since the sub.ksh script is executed at the background,I started another process(new.ksh) in the foreground. The new.ksh also logs the information in main_ddmmyy file . The new.ksh script is executed properly and logs the information in its log file, but the sub.ksh script is not logging the information in its logfile when I have process both in foreground and background. If I don't start the process(new.ksh),the information from the background script(sub.ksh) is logged properly.

Hope I have made you clear.

I am not able to figure out where the problem is. Please help me on it.

Thanks in advance
Chella
