-h   Don't print the header.

-u   Ignores  the username while figuring out the current process and cpu times.  To demonstrate this, do
     a "su" and do a "w" and a "w -u".

-s   Use the short format.  Don't print the login time, JCPU or PCPU times.

-f   Toggle printing the from (remote hostname) field.  The default as released is for the from field  to
     not  be  printed,  although your system administrator or distribution maintainer may have compiled a
     version in which the from field is shown by default.

-V   Display version information.

-o   Old style output. Prints blank space for idle times less than one minute.
