confusing ps command

The manpage explains it quite clearly.

The -f flag to ps tells ps to generate a "full" listing, so rather than just listing pid, tty, time and the command, it will also display things like memory usage, user, stime and arguments.

-p just returns the a non-full list of the processes specified as its argument.

You can combine arguments, so for example:

ps -ef |grep 13806

will return the same thing as

ps -fp 13806

see "man ps".
