       term - conventional names for terminals

       Terminal	 names	are maintained as part of the shell environment	in the
       environment variable TERM  (see	sh(1),	profile(4),  and  environ(5)).
       These  names are	used by	certain	commands (for example, tabs, tput, and
       vi) and certain functions (for example, see curses(3X)).

       Files under /usr/share/lib/terminfo are used to name terminals and  de-
       scribe  their capabilities.  These files	are in the format described in
       terminfo(4).  Entries in	terminfo source	files consist of a  number  of
       comma-separated fields.	To print a description of a terminal term, use
       the command infocmp -I term (see	infocmp(1M)).  White space after  each
       comma  is  ignored.  The	first line of each terminal description	in the
       terminfo	database gives the names by which terminfo knows the terminal,
       separated by bar	(|) characters.	 The first name	given is the most com-
       mon abbreviation	for the	terminal (this is the one to use  to  set  the
       environment  variable  TERMINFO in $HOME/.profile; see profile(4)), the
       last name given should be a long	name fully identifying	the  terminal,
       and  all	 others	are understood as synonyms for the terminal name.  All
       names but the last should contain no blanks and must be unique  in  the
       first 14	characters; the	last name may contain blanks for readability.

       Terminal	 names	(except	 for the last, verbose entry) should be	chosen
       using the following conventions.	 The particular	piece of hardware mak-
       ing  up	the  terminal should have a root name chosen, for example, for
       the AT&T	4425 terminal, att4425.	 This name should not contain hyphens,
       except  that  synonyms  may  be	chosen that do not conflict with other
       names.  Up to 8 characters, chosen from the  set	 a  through  z	and  0
       through	9,  make  up a basic terminal name.  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.  Terminal sub-models, operational modes that the hardware can  be
       in,  or	user preferences should	be indicated by	appending a hyphen and
       an indicator of the mode.  Thus,	an AT&T	4425 terminal  in  132	column
       mode  is	att4425-w.  The	following suffixes should be used where	possi-

       Suffix  Meaning				     Example

       -w      Wide mode (more than 80 columns)	     att4425-w
       -am     With auto. margins (usually default)  vt100-am
       -nam    Without automatic margins	     vt100-nam
       -n      Number of lines on the screen	     aaa-60
       -na     No arrow	keys (leave them in local)   c100-na
       -np     Number of pages of memory	     c100-4p
       -rv     Reverse video			     att4415-rv

       To avoid	conflicts with the naming conventions used in  describing  the
       different modes of a terminal (for example, -w),	it is recommended that
       a terminal's root name not contain hyphens.  Further, it	is good	 prac-
       tice  to	 make  all  terminal  names  used  in the terminfo(4) database
       unique.	Terminal entries that are present only for inclusion in	 other
       entries	via the	use= facilities	should have a '+' in their name, as in

       Here are	some of	the known terminal names: (For a complete list,	 enter
       the command
       ls -C /usr/share/lib/terminfo/? ).

       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.
