How to print only process numbers for the SSH server in Ubuntu command

Question

I know we can print every process on the Ubuntu system with this command:

ps -au

But How to print only process numbers for the SSH server?

Answer 1

If you want to see just the process numbers, you can use:

pgrep sshd

If you would like to see columns of data with more information than process numbers, you can use:

pgrep -a sshd

or

ps -aux|grep '[s]shd'
