TERM(M) UNIX System V
Name
term - conventional names for terminals
Description
These names are used by certain commands [e.g., man(C),
tabs(C), tput(C), vi(C) and curses(S)] and are maintained as
part of the shell environment in the environment variable
TERM [see sh(C), profile(F), and environ(M)].
Entries in terminfo(F) source files consist of a number of
comma-separated fields. [To obtain the source description
for a terminal, use the -I option of infocmp(ADM).] White
space after each comma is ignored. The first line of each
terminal description in the terminfo(F) data base gives the
names by which terminfo(F) knows the terminal, separated by
bar ( | ) characters. The first name given is the most
common abbreviation for the terminal [this is the one to use
to set the environment variable TERMINFO in $HOME/.profile;
see profile(F)], 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 making up the terminal should have a root
name chosen. For example, for the AT&T 4425 terminal, the
root name is 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 [a-z0-9], 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
would be att4425-w. The following suffixes should be used
where possible:
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 (e.g., -w), it
is recommended that a terminal's root name not contain
hyphens. Further, it is good practice to make all terminal
names used in the terminfo(F) data base unique. Terminal
entries that are present only for inclusion in other entries
via the use= facilities should have a '+' in their name, as
in 4415+nl.

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.
