* NT Workstation already has finger, and it runs fine under
|

|
* access to NT.
|
|
* Had to remove local handling. Otherwise, same as whois.

/*
|
|
* Finger prints out information about users. It is not portable since
|
|
* certain fields (e.g. the full user name, office, and phone numbers) are
|
|
* extracted from the gecos field of the passwd file which other UNIXes
|
|
* may not have or may use for other things.
|
|
*
|
|
* There are currently two output formats; the short format is one line
|
|
* per user and displays login name, tty, login time, real name, idle time,
|
|
* and office location/phone number. The long format gives the same
|
|
* information (in a more legible format) as well as home directory, shell,
|
|
* mail info, and .plan/.project files.
