To finger someone

   finger UserID@fully.qualified.domain.name

On some systems finger is linked to f so the following also works:

   f UserID@fqdn


Finger displays different information on different systems.  Often it will 
display your full name, your default shell, when your were last logged on, 
and your ~/.plan and ~/.project files.

If you finger someone and the display takes more than one page you can pipe 
the output through less (or more if you don't have less).  For example to 
find out about Halcyon, my Internet service provider, type:

   finger info@halcyon.com |less


Finger can also be used to display information about groups of people.
For example:

   finger john@random.fqdn |less

Ths will display finger information about everyone with ``john'' in 
their name on random.fqdn.  You can get a short listing for each person
by using:

   finger -q john@random.fqdn |less


For technical details about the finger protocol see RFC1288.
