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

How do I start a background process and save the process id to a file on my system. For example %wait 5 & will execute and print the process id. I can't figure out how to get it to a file. I've tried: > filename 0>filename 1>filename.
Any assistance is most appreciated.

times(1) User Commands times(1)
NAME
times - shell built-in function to report time usages of the current shell
SYNOPSIS
sh
times
ksh
times
DESCRIPTION
sh
Print the accumulated user and system times for processes run from the shell.
ksh
Print the accumulated user and system times for the shell and for processes run from the shell.
On this man page, ksh(1) commands that are preceded by one or two * (asterisks) are treated specially in the following ways:
1. Variable assignment lists preceding the command remain in effect when the command completes.
2. I/O redirections are processed after variable assignments.
3. Errors cause a script that contains them to abort.
4. Words, following a command preceded by ** that are in the format of a variable assignment, are expanded with the same rules as a vari-
able assignment. This means that tilde substitution is performed after the = sign and word splitting and file name generation are not
performed.
