Expert Solution

ps -ef command is used to lists all the process in the full format that are currently running in your machine, it includes UID(who have started the process), PID(ID of each process, its unique), PPID(It represents the ID of the parent process, it's not unique) and CMD(to run that process)

These all information helps us to identify who have started which process and we can easily kill those processes if we want.

Output:

If you're using grep tty | less, then it will simply open up the result of ps -ef in a command line in an interactive shell while less command is used to print information page wise.

ps -A: to list down active processes

ps -ef: to list down processes in full format

I hope it helps.
