41.Nd terminal capability interface
42.Sh SYNOPSIS
43.Nm tput
44.Op Fl T Ar term
45.Ar attribute
46.Op Ar attribute-args
47.Ar ...
48.Sh DESCRIPTION
49.Nm Tput
50makes terminal-dependent information available to users or shell
51applications.
52The options are as follows:
53.Bl -tag -width Ds
54.It Fl T
55The terminal name as specified in the
56.Xr termcap
57database, for example, ``vt100'' or ``xterm''.
58If not specified,
59.Nm tput
60retrieves the
61.Dq Ev TERM
62variable from the environment.
63.El
64.Pp
65.Nm Tput
66outputs a string if the
67.Ar attribute
68is of type string; a number if it is of type integer.
69Otherwise,
70.Nm tput
71exits 0 if the terminal has the capability and 1 if it does not,
72without further action.
73.Pp
74If the
75.Ar attribute
76is of type string, and takes arguments (e.g. cursor movement,
77the termcap
78.Dq cm
79sequence) the arguments are taken from the command line immediately
80following the attribute.
81.Pp
82The following special attributes are available:
83.Bl -tag -width Ar
84.It clear
85Clear the screen (the
86.Xr termcap
87``cl'' sequence).
88.It init
89Initialize the terminal (the
90.Xr termcap
91``is'' sequence).
92.It longname
93Print the descriptive name of the user's terminal type.
94.It reset
95Reset the terminal (the
96.Xr termcap
97``rs'' sequence).
98.Sh DIAGNOSTICS
99The exit value of
100.Nm tput
101is based on the last attribute specified.
102If the attribute is of type string or of type integer,
103.Nm tput
104exits 0 if the attribute is defined for this terminal type and 1
105if it is not.
106If the attribute is of type boolean,
107.Nm tput
108exits 0 if the terminal has this attribute, and 1 if it does not.
109.Nm Tput
110exits 2 if any error occurred.
111.Sh EXAMPLES
112.Bl -tag -width "tput cm 6 11 DC 6" -compact
113.It Li "tput cl cm 5 10"
