$ ps -e

the first column is the PID. the second column, TTY, is not always relevant, and can usually be ignored. the third column, TIME, is the total accumulated CPU time thus far; it's seldom very interesting. the last column is the name of the process binary.

what doesn't show up here is that "ps -e" lists everybody's processes, not just your own. this may or may not be what you want to see. for information on how to modify this, and other, aspects of the "ps" output, see "man ps".
