|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
utility makes terminal-dependent information available to users or shell
|
|
applications.
|
|
When invoked as the
|
|
.Nm clear
|
|
utility, the screen will be cleared as if
|
|
.Dl tput clear
|
|
had been executed.
|
|
The options to
|
|
.Nm
|
|
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
|
|
The
|
|
.Nm
|
|
utility outputs a string for each
|
|
.Ar attribute
|
|
that is of type string; a number for each of type integer.
|
|
Otherwise,
|
|
.Nm
|
|
exits 0 if the terminal has the capability and 1 if it does not,
|
|
without further action.
|
|
.Pp
|
|
If an
|
|
.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 Cm clear
|
|
Clear the screen (the
|
|
.Xr termcap 5
|
|
.Dq cl
|
|
sequence).
|
|
.It Cm init
|
|
Initialize the terminal (the
|
|
.Xr termcap 5
|
|
.Dq is
|
|

|
|
.It Cm longname
|
|
Print the descriptive name of the user's terminal type.
|
|
.It Cm reset
|
|

|
|

|
|
sequence).
|
|
.El
|
|
.Sh EXIT STATUS
|
|
The exit status of
|
|
.Nm
|
|
is as follows:
|
|
.Bl -tag -width indent
|
|
.It 0
|
|
If the last attribute
|
|
.Ar attribute
|
|
argument is of type string or integer, its value was successfully written
|
|
to standard output.
|
|
If the argument is of type boolean, the terminal has this attribute.
|
|
.It 1
|
|
This terminal does not have the specified boolean
|
|
.Ar attribute .
|
|
.It 2
|
|
Usage error.
|
|

|
|
.Sh STANDARDS
|
|
The
|
|
.Nm
|
|
utility conforms to
|
|
.St -p1003.1-2001 .
|
|
.Sh HISTORY
|
|
The
|
|
.Nm
|
|
utility appeared in
|
|
.Bx 4.4 .
|
|
.Sh BUGS
|
|
The
|
|
.Nm
|
|
utility cannot really distinguish between different types of attributes.
|
|
.Pp
|
|
Some termcap entries depend upon having a
|
|
.Sq %
|
|
in them that is just a
|
|
.Sq %
|
|
and nothing more.
|
|
Right now we just warn about them if they do not
|
|
have a valid type declaration.
|
|
These warnings are sent to
|
|
stderr.
