how to check whether a process started at particular time
I want to check whether a particular process has started at 10:00a.m or not.
I can check process by ps -fu but dont know how to check it with respect to time. Could anyone help me with this?

From man at:

at executes commands at a specified time.
Is if you want to run it at particular time, you'd use at.
If you just need to check when it started, and you don't have much control about how it started or when, then just look at the output of ps. You should see a column START that lists the start times.

Just add date to the code....

Are you redirecting your output to any file..?

Check if you can implement this.Smilie

Code:
if [ -z $ "k" ]
then
echo "billing done" >> output.log
date  >> output.log
fi
