The fields output are: the users login name, the name of the tty the user is on, the time of day the user logged on, the number of minutes since the user last typed anything, the CPU time used by all processes and their children on that terminal, the CPU time used by the currently active processes, the name and arguments of the current process.
The -h flag suppresses the heading. The -s flag asks for a short form of output. In the short form, the tty is abbreviated, the login time and cpu times are left off, as are the arguments to commands. -l gives the long output, which is the default.
If a user name is included, the output will be restricted to that user.
The CPU time is only an estimate, in particular, if someone leaves a background process running after logging out, the person currently on that terminal is ``charged'' with the time.
Background processes are not shown, even though they account for much of the load on the system.
Sometimes processes, typically those in the background, are printed with null or garbaged arguments. In these cases, the name of the command is printed in parentheses.
W does not know about the new conventions for detection of background jobs. It will sometimes find a background job instead of the right one.
