Question

Hi Team.

I have one requirement to run more than one command at a time in the bash shell. How can I do that?

Hi@akhtar,

You can run multiple commands in your bash shell. In this scenario, you need to use backquote as shown below. 

$ ps -o rss `pgrep python3`

This command will find the process ID of the python3 program. Then it will find the resident set size of the process.
