what does ps aux | egrep......mean?
Hey guys well, i killed a user that was ssh into my machine and a googled how to do it, however the command that I used to find he PID was
ps aux | egrep "sshd: [a-zA-Z]+@"
why not just use ps aux | grep sshd?
also can someone decipher what ps aux | egrep "sshd: [a-zA-Z]+@" means? I am not that advanced to understand what I googled on that? Also, is there a good tutorial to teach you those commands in depth like that? And what are they called? the (egrep "sshd: [a-zA-Z]+@") part.
