.Sh SYNOPSIS
|

|
|
.Ar attribute
|
|
.Op Ar attribute-args
|
|
.Ar ...
|
|
.Sh DESCRIPTION
|
|
.Nm
|
|
makes terminal-dependent information available to users or shell
|
|
applications.
|
|
The options are as follows:
|
|
.Bl -tag -width Ds
|
|
.It Fl T
|
|
The terminal name as specified in the
|
|
.Xr termcap 5
|
|
database, for example,
|
|
.Dq vt100
|
|
or
|
|
.Dq xterm .
|
|
If not specified,
|
|
.Nm
|
|
retrieves the
|
|
.Dq Ev TERM
|
|
variable from the environment.
|
|
.El
|
|
.Pp
|
|
.Nm
|
|
outputs a string if the
|
|
.Ar attribute
|
|
is of type string; a number if it is of type integer.
|
|
Otherwise,
|
|
.Nm
|
|
exits 0 if the terminal has the capability and 1 if it does not,
|
|
without further action.
|
|
.Pp
|
|
If the
|
|
.Ar attribute
|
|
is of type string, and takes arguments (e.g. cursor movement,
|
|
the termcap
|
|
.Dq cm
|
|
sequence) the arguments are taken from the command line immediately
|
|
following the attribute.
|
|
.Pp
|
|
The following special attributes are available:
|
|
.Bl -tag -width Ar
|
|
.It clear
|
|
Clear the screen (the
|
|
.Xr termcap 5
|
|
.Dq cl
|
|
sequence).
|
|
.It init
|
|
Initialize the terminal (the
|
|
.Xr termcap 5
|
|
.Dq is
|
|
sequence).
|
|
.It longname
|
|
Print the descriptive name of the user's terminal type.
|
|
.It reset
|
|
Reset the terminal (the
|
|
.Xr termcap 5
|
|
.Dq rs
|
|
sequence).
|
|
.El
|
|
.Sh EXIT STATUS
|
|
The exit status of
|
|
.Nm
|
|
is based on the last attribute specified.
|
|
If the attribute is of type string or of type integer,
|
|
.Nm
|
|
exits 0 if the attribute is defined for this terminal type and 1
|
|
if it is not.
|
|
If the attribute is of type boolean,
|
|
.Nm
|
|
exits 0 if the terminal has this attribute, and 1 if it does not.
|
|
.Nm
|
|
exits 2 if any error occurred.
|
|
.Sh EXAMPLES
|
|
.Bl -tag -width "tput cm 6 11 DC 6" -compact
|
|
.It Li "tput cl cm 5 10"
|
|
clear the screen and goto line 5 column 10
|
|
.Pp
|
|
.It Li "tput cm 6 11 DC 6"
|
|
goto line 6 column 11 and delete 6 characters
|
|
.El

|
|

|
|
.Sh HISTORY
|
|
The
|
|
.Nm
|
|
command appears in
|
|
.Bx 4.4 .
|
|
.Sh BUGS
|
|
.Nm
|
|
can't really distinguish between different types of attributes.
|
|
.Pp
|
|
Not all termcap entries contain the reset sequence, so using the init
|
|
sequence may be more useful.
