What is Finger?

If an account is fingerable, fingering that account will tell you various information about that account. What information is returned varies from account to account. Usually there is information such as the real name of the person whose account it is, the last time they logged into that account, and perhaps a "plan" file.

Some accounts, however, are not fingerable. This is because:


The time/date of last login is no longer a good barometer of when the person last used their account. People used to login to their "shell" (unix, vax, etc.) account quite often. Some still do. But many people rarely use their shell account, but still use the account for e-mail via a mail program on their desktop computer. Thus a person may still be checking mail daily but be registered as not having logged in for months. Other systems routinely return "Never logged in" for all accounts.<

Plan files are a lost art. I think of plans as precursors to Web pages. They are text files that can be short or long, and give whatever information a person wishes to put there, whether it be office hours, witty quotes, etc. Some machines only allow the plans to be read when someone is fingering from the same system.

How to finger

Usually you finger someone with their e-mail address.

From your Mac or Windows machine:

Via the World Wide Web: Via e-mail:
Send e-mail to infobot@infomania.com with a subject line of FINGER chz1@cornell.edu

From a shell (unix or vax) account:
General format:
$ finger joeblow@xyz.edu

To finger someone on the same system from which you are fingering:
$ finger janedoe

On unix machines, frequently you can finger by parts of a name:
$ finger davis@abc.edu (will return all Davises)

Be careful with the above -- if you do this for common names, or last names that are common first names, you will be flooded with data.

To find out who is currently logged into the shell system:
$ finger
To see who is currently logged into another system:
$ finger @abc.edu

How to be fingered

In prior days, when more people used shell accounts, "Finger Me!" was heard at campuses around the world!

On a Unix or Vax shell account:

To be fingered on your Mac or Windows:
If you have a shell account, you can still be fingered through your shell account and have a plan file there.

To be fingered on your desktop machine:
Your computer needs its own IP address when it connects with the internet. (Preferably a static one; a dynamic one would still be fingerable, but people would not know what address to finger you at)
You also need to download a finger server:
