... ... 2.1.3 Fingering Yourself

To finger yourself by type the following at your Unix prompt.

    finger YourUserID

For a different view of your finger information, and also to see
who else is currently logged in, type:

    finger

To ensure that people from other systems can finger you should ask someone 
who's not on your system to finger you too.  It is possible for you to
simulate fingering yourself from another machine (another.fqdn) by doing 
this:

    finger YourUserID@your.fqdn@another.fqdn

In order for this to work another.fqdn must support full finger functionality.
