finger: [WAITS, via BSD Unix] 1. n. A program that displays
information about a particular user or all users logged on the
system, or a remote system. Typically shows full name, last login
time, idle time, terminal line, and terminal location (where
applicable). May also display a plan file left by the user (see
also Hacking X for Y). 2. vt. To apply finger to a username. 3.
vt. By extension, to check a human's current state by any means.
"Foodp?" "T!" "OK, finger Lisa and see if she's idle." 4. Any
picture (composed of ASCII characters) depicting `the finger'.
Originally a humorous component of one's plan file to deter the
curious fingerer (sense 2), it has entered the arsenal of some
flamers.
