Processes
Any program that executes in userland spawns one or more processes, each of which has a process ID (PID).
Listing:
- $ ps auxf : List all ProcesseS in tree format
- $ top -c : Show list of most resource-intensive processes
Killing:
- $ kill <PID> : Sends a TERMinate signal to the process. Works only if you own the process, or are root
- $ killall <process name> : Kill processes by name (dangerous but convenient)
- $ kill -9 <PID> : Send a KILL signal to the process (last resort for something that's not responding)
Notes:
