term(5)
NAME
term - conventional names for terminals
DESCRIPTION
Terminal names are maintained as part of the shell environ-
ment in the environment variable TERM. See sh(1), pro-
file(4), and environ(5). These names are used by certain
commands (for example, tabs, tput, and vi) and certain func-
tions (for example, see curses(3CURSES)).
Files under /usr/share/lib/terminfo are used to name termi-
nals and describe 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 descrip-
tion in the terminfo database gives the names by which ter-
minfo 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(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 making 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 possible:
Suffix Meaning Example
-w Wide mode (more than 80 columns) att4425-w
-am With auto. margins (usually vt100-am
default)
-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 con-
tain hyphens. Further, it is good practice to make all ter-
minal names used in the terminfo(4) database unique. Termi-
nal entries that are present only for inclusion in other
entries via the use= facilities should have a '+' in their
name, as in 4415+nl.
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.
