tput - initialize a terminal or query the terminfo database

---

SYNOPSIS

/usr/5bin/tput [ -Ttype ] init

/usr/5bin/tput [ -Ttype ] longname

/usr/5bin/tput [ -Ttype ] reset

AVAILABILITY

This command is available with the System V software installation option. Refer to [a manual with the abbreviation INSTALL] for information on how to install optional software.

DESCRIPTION

tput uses the terminfo.5v database to make the values of terminal-dependent capabilities and information available to the shell, to initialize or reset the terminal, or return the long name of the requested terminal type. Normally, the terminal type is taken from the environment variable TERM; if the -Ttype option is specified, the terminal type is taken from that option.

tput displays a string if the given capability is a string capability, or an integer if it is an integer capability; it displays no output if the capability is a boolean.

If capability is a boolean, tput returns true (0) if that capability is set, or false (1) otherwise. If capability is a string, tput returns true (0) if that capability is set, or false (1) otherwise. If capability is an integer, a value of true (0) is returned whether or not the capability is set for the terminal. To determine if an integer capability is set, you must examine the standard output.

For a complete list of capabilities and the capability associated with each, see terminfo.5v

If capability is a string capability that takes parameters, the parameter arguments are instantiated into the string. An all-numeric parameter argument is passed to the attribute as a number.

OPTIONS

-Ttype

Indicate the type of terminal. If this option is supplied, the environment variables LINES and COLUMNS are not used.

init

If the terminfo database is present and an entry for the user's terminal exists, emit the terminal's initialization strings, set up any delays specified, and turn the expansion of TAB characters on or off, as specified by the terminal's entry in the terminfo database. If the terminal has a TAB character, and either has a capability for setting TAB characters or initially has its TAB characters set every 8 SPACE characters, expansion of TAB characters is turned off, otherwise expansion of TAB characters is turned on. If expansion of TAB characters is turned on, and the terminal has a capability for setting TAB characters, TAB stops are set to every eight columns. If an entry does not contain the information needed for any of these actions, that action is silently skipped.

reset

Emit the terminal's reset strings, and set up delays and TAB characters as specified. If the reset strings are not present, but initialization strings are, the initialization strings are used.

longname

If the terminfo database is present and an entry for the user's terminal exists, emit the long name of the terminal. The long name is the last name in the first line of the terminal's description in the terminfo database.

EXIT CODES

0

The boolean or string capability is set, or the capability is an integer type and is present.

1

The capability is not set.

2

Usage error.

3

The terminal is of an unknown type, or the terminfo database is not present.

4

Unknown terminfo capability.

-1

The integer capability is not defined for this terminal type.

EXAMPLES

tput init

Initialize the terminal according to the type of terminal in the environmental variable TERM. This command can be included in a .profile or .login file.

tput -Tsun reset

Reset a Sun workstation console, shelltool.1 window, or cmdtool.1 window, overriding the type of terminal in the environmental variable TERM.

tput cup 0 0

Send the sequence to move the cursor to row 0, column 0 (the upper left corner of the screen, usually known as the ``home'' cursor position).

tput clear

Echo the clear-screen sequence for the current terminal.

tput cols

Print the number of columns for the current terminal.

tput -Tsun cols

Print the number of columns for the Sun workstation console or subwindow.

bold=`tput smso`

offbold=`tput rmso`

Set the shell variables bold, to begin stand-out mode sequence, and offbold, to end standout mode sequence, for the current terminal. This might be followed by a prompt:

echo "${bold}Please type in your name: ${offbold}\c"

tput hc

Set exit code to indicate if the current terminal is a hardcopy terminal.

tput cup 23 4

Send the sequence to move the cursor to row 23, column 4.

tput longname

Print the long name from the terminfo database for the type of terminal specified in the environmental variable TERM.
