Meaning of columns from ps

Question

In Linux bash, what do the four columns mean from ps?

e.g

PID   TTY         TIME CMD
15286 pts/498 00:00:00 bash
30887 pts/498 00:00:00 ps

Answer 1

From the man page:

It displays the process ID (pid=PID), the terminal associated with the process (tname=TTY), the cumulated CPU time in [dd-]hh:mm:ss format (time=TIME), and the executable name (ucmd=CMD).
