NAME
tputclear
- terminal capability interface
SYNOPSIS
[-T term
]
attribute ... clear
DESCRIPTION
The
utility makes terminal-dependent information available to users or shell
applications.
When invoked as the
clear
utility, the screen will be cleared as if
tput clear
had been executed.
The options to
are as follows:
-T
The terminal name as specified in the
termcap(5)
database, for example,
``vt100''
or
``xterm''
If not specified,
retrieves the
``TERM
''
variable from the environment.
The
utility outputs a string for each
attribute
that is of type string; a number for each of type integer.
Otherwise,
exits 0 if the terminal has the capability and 1 if it does not,
without further action.
If an
attribute
is of type string, and takes arguments (e.g. cursor movement,
the termcap
``cm''
sequence) the arguments are taken from the command line immediately
following the attribute.
The following special attributes are available:
clear
Clear the screen (the
termcap(5)
``cl''
sequence).
init
Initialize the terminal (the
termcap(5)
``is''
sequence).
longname
Print the descriptive name of the user's terminal type.
reset
Reset the terminal (the
termcap(5)
``rs''
sequence).
EXIT STATUS
The exit status of
is as follows:
0
If the last attribute
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.
1
This terminal does not have the specified boolean
attribute
2
Usage error.
3
No information is available about the specified terminal type.
The
utility cannot really distinguish between different types of attributes.
Some termcap entries depend upon having a
`%'
in them that is just a
`%'
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.
