Renumber cluase 4 to 3, per what everybody else did when BSD granted them permission to remove clause 3. My insistance on keeping the same numbering for legal reasons is too pedantic, so give up on that point.

|
|
.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
|
|
sequence).
|
|
.It Cm longname
|
|
Print the descriptive name of the user's terminal type.
|
|
.It Cm reset
|
|
Reset the terminal (the
|
|
.Xr termcap 5
|
|
.Dq rs
|
|
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.
|
|
.It 3
|
|
No information is available about the specified terminal type.

|
|
.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.
