At work you have a few Linux servers and are asked to troubleshoot why a webserver on one of them is not responding. You SSH onto the server and want to determine if the webserver process is running. Which command would you use?
grep
ps
ls
tasklist
The ps command is a Linux and Mac command for listing processes. It is also an alias for Get-Process in PowerShell. The command will list running processes and various details about them. It is a great start to determine if something is running on a Linux machine.
