Level Up 1: Can use ps to find daemon processes

gistfile1.txt

1. If you run the command `ruby -e 'sleep 1 while true'`, you'll start a ruby process that never completes. Try it out and verify that the command never returns. Use the keyboard command to kill it.

Used ctr-c to kill the job

2. Try it again, but append the character that causes the process to run in the background.

ruby -e 'sleep 1 while true' &

3. Use the terminal command to bring it back to the foreground, then use the two keyboard commands to return it to the background.

fg
ctr-Z then bg

4. List the processes on your system and find the PID that corresponds to that ruby script.

ps
My PID is: 45536

5. Since we don't want to repeat that debacle above, use the terminal command to rudely kill the ruby process based on its PID.

kill 45536
