I am currently using this command to get some information about some specific processes:

ps -C beam.smp -o pid,user:20,%cpu,%mem,args

As I use it for two process names, I would like to do it in one command in order to get a snapshot. Like that:

ps -C beam.smp,docker -o pid,user:20,%cpu,%mem,args

The problem is that the output does not display a specific column with beam.smp or docker, which would be really useful for me. How could I get a new line in my output showing that?


Use the comm format specifier:

ps -C beam.smp,docker -o pid,user:20,%cpu,%mem,comm,args

This shows the command name, which is exactly what you're filtering on with the -C selector.
