Unix shell script to query linux top consuming processes

Hi All,

O/S: Linux 86x64 Red Hat

I have a sql script that queries top consuming processes of Linux using TOP commnd.

Now I need to automate this task and pass the top processes i.e., PID to the sql script through unix shell script.

Could anyone please let me know how to achieve this.

Thanks for your time!

Regards,

We need to see the existing script to help you further!!! Can you share the SQL query? What do you mean by "automate this task and pass the top processes" if the SQL script can derive the CPU eating processes using by itself as you mentioned?

Please clarify your goal, so that we can help you!!

Hi admin_xor,

Thanks for your time and attention to the issue.

Sorry let me be more clear here please:

Presently what we are doing is:

1) Issue Top command manually
2) Pass the PID of the top consuming processes to the sql statement to get the SQL_TEXT

GOAL:

1) In a single shell script, capture all the top CPU consuming processes
2) Pass such captured all the top CPU consuming processes i.e PID to the sql statement to get the SQL_TEXT


I am including my sq statement for your Ref please.

Thanks,
