How can i get the parent process only?
Hello,
I'm running one script every night and that's kick off through cron jobs.
Inside the script i'm checking whether my script is already running or not.
I'm using following command to check whether is running or not.
ps -eaf | grep "test_PID.ksh" | grep -v "grep test_PID.ksh" | wc -l
sometime it gives me 2 process or 3 process
Output:
user 15243 15203 0 12:00:01 ? 0:00 /usr/bin/ksh /usr/local/my/bin/test_PID.ksh
user 15203 254 0 12:00:01 ? 0:00 sh -c /usr/local/my/bin/test_PID.ksh
Why am i seeing two process for one job.
How can i get only parent process not child process.
Thank you for your helps in adv.

uudemon.cleanu
uudemon(4) Kernel Interfaces Manual uudemon(4)
NAME
uudemon.admin, uudemon.cleanu, uudemon.hour, uudemon.poll - Administrative shell scripts for polling remote systems, cleaning up spool
directories, reporting status to the system administrator, and routine invocations of the uuxqt and uusched daemons
SYNOPSIS
These shell scripts reside in the following directory:
/usr/lib/uucp
DESCRIPTION
All the scripts can be run from the command line or can be run automatically by the cron daemon. To automatically run the scripts, remove
the comment character (#) from the beginning of the relevant line in the /var/spool/cron/crontabs/uucp file.
This script reports status to the system administrator. It issues the uustat command to find out the status of uucp jobs. It mails the
results to the uucp login ID. The script may be modified to send mail to any login ID such as the uucp administrative login ID (uucpa) or
root. This script cleans up the /var/spool/uucp and /var/spool/uucppublic directories by running the uucleanup command. The uucleanup com-
mand is run with the following parameters: -C7, -D7, X2, -o2, -W1. This script runs the uusched and uuxqt daemons in the background. This
script polls the systems listed in the /usr/lib/uucp/Poll file. The uudemon.poll script should be scheduled before the uudemon.hour
script. This allows uudemon.poll to create any command files before cron runs the uudemon.hour script.
FILES
Contains the uudemon.admin, uudemon.cleanu, uudemon.hour and uudemon.poll files. Contains the uucp file.
RELATED INFORMATION
Commands: cron(8), uucleanup(8), uusched(8), uuxqt(1)
