DESCRIPTION

These names are used by certain commands (e.g., nroff(1), mm(1), man(1), tabs(1)) and are maintained as part of the shell environment (see sh(1), profile(5), and environ(7)) in the variable $TERM:

Up to 8 characters, chosen from [−a−z0−9], make up a basic terminal name.  Terminal sub-models and operational modes are distinguished by suffixes beginning with a −.  Names should generally be based on original vendors, rather than local distributors.  A terminal acquired from one vendor should not have more than one distinct basic name. 

Commands whose behavior depends on the type of terminal should accept arguments of the form −Tterm where term is one of the names given above; if no such argument is present, such commands should obtain the terminal type from the environment variable $TERM, which, in turn, should contain term.

BUGS

This is a small candle trying to illuminate a large, dark problem.  Programs that ought to adhere to this nomenclature do so somewhat fitfully.
