NAME
@TPUT@, reset - initialize a terminal or query terminfo database
SYNOPSIS
@TPUT@ [-Ttype] capname [parms ... ]
@TPUT@ [-Ttype] init
@TPUT@ [-Ttype] reset
@TPUT@ [-Ttype] longname
@TPUT@ -S <<
@TPUT@ -V
DESCRIPTION
The @TPUT@ utility uses the terminfo database to make the values of
terminal-dependent capabilities and information available to the shell
(see sh(1)), to initialize or reset the terminal, or return the long
name of the requested terminal type. The result depends upon the
capability's type:
string
@TPUT@ writes the string to the standard output. No
trailing newline is supplied.
integer
@TPUT@ writes the decimal value to the standard output, with
a trailing newline.
boolean
@TPUT@ simply sets the exit code (0 for TRUE if the terminal
has the capability, 1 for FALSE if it does not), and writes
nothing to the standard output.
Before using a value returned on the standard output, the application
should test the exit code (e.g., $?, see sh(1)) to be sure it is 0.
(See the EXIT CODES and DIAGNOSTICS sections.) For a complete list of
capabilities and the capname associated with each, see terminfo(5).
-Ttype
indicates the type of terminal. Normally this option is
unnecessary, because the default is taken from the environment
variable TERM. If -T is specified, then the shell variables
LINES and COLUMNS will be ignored,and the operating system will
not be queried for the actual screen size.
capname
indicates the capability from the terminfo database. When
termcap support is compiled in, the termcap name for the
capability is also accepted.
parms
If the capability is a string that takes parameters, the
arguments parms will be instantiated into the string.

@TPUT@(1) @TPUT@(1)
Most parameters are numbers. Only a few terminfo capabilities
require string parameters; @TPUT@ uses a table to decide which to
pass as strings. Normally @TPUT@ uses tparm (3X) to perform the
substitution. If no parameters are given for the capability,
@TPUT@ writes the string without performing the substitution.
-S allows more than one capability per invocation of @TPUT@. The
capabilities must be passed to @TPUT@ from the standard input
instead of from the command line (see example). Only one capname
is allowed per line. The -S option changes the meaning of the 0
and 1 boolean and string exit codes (see the EXIT CODES section).
Again, @TPUT@ uses a table and the presence of parameters in its
input to decide whether to use tparm (3X), and how to interpret
the parameters.
-V reports the version of ncurses which was used in this program,
and exits.
init If the terminfo database is present and an entry for the user's
terminal exists (see -Ttype, above), the following will occur:
(1) if present, the terminal's initialization strings will be
output as detailed in the terminfo(5) section on Tabs and
Initialization,
(2) any delays (e.g., newline) specified in the entry will be
set in the tty driver,
(3) tabs expansion will be turned on or off according to the
specification in the entry, and
(4) if tabs are not expanded, standard tabs will be set (every 8
spaces).
If an entry does not contain the information needed for any of
the four above activities, that activity will silently be
skipped.
reset
Instead of putting out initialization strings, the terminal's
reset strings will be output if present (rs1, rs2, rs3, rf). If
the reset strings are not present, but initialization strings
are, the initialization strings will be output. Otherwise, reset
acts identically to init.
longname
If the terminfo database is present and an entry for the user's
terminal exists (see -Ttype above), then the long name of the
terminal will be put out. The long name is the last name in the
first line of the terminal's description in the terminfo database

[see term(5)].
If @TPUT@ is invoked by a link named reset, this has the same effect
as @TPUT@ reset. See tset for comparison, which has similar behavior.
EXAMPLES
@TPUT@ init
Initialize the terminal according to the type of terminal in the
environmental variable TERM. This command should be included in
everyone's .profile after the environmental variable TERM has
been exported, as illustrated on the profile(5) manual page.
@TPUT@ -T5620 reset
Reset an AT&T 5620 terminal, 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@ -T450 cols
Print the number of columns for the 450 terminal.
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 hard copy
terminal.
@TPUT@ cup 23 4
Send the sequence to move the cursor to row 23, column 4.
@TPUT@ cup
Send the terminfo string for cursor-movement, with no parameters
substituted.
@TPUT@ longname
Print the long name from the terminfo database for the type of
terminal specified in the environmental variable TERM.

@TPUT@ -S <<!

This example shows @TPUT@ processing several capabilities in one
invocation. It clears the screen, moves the cursor to position
10, 10 and turns on bold (extra bright) mode. The list is
terminated by an exclamation mark (!) on a line by itself.
FILES
@TERMINFO@
compiled terminal description database
@DATADIR@/tabset/*
tab settings for some terminals, in a format appropriate to be
output to the terminal (escape sequences that set margins and
tabs); for more information, see the "Tabs and Initialization"
section of terminfo(5)
EXIT CODES
If the -S option is used, @TPUT@ checks for errors from each line, and
if any errors are found, will set the exit code to 4 plus the number
of lines with errors. If no errors are found, the exit code is 0. No
indication of which line failed can be given so exit code 1 will never
appear. Exit codes 2, 3, and 4 retain their usual interpretation. If
the -S option is not used, the exit code depends on the type of
capname:
boolean
a value of 0 is set for TRUE and 1 for FALSE.
string
a value of 0 is set if the capname is defined for this
terminal type (the value of capname is returned on standard
output); a value of 1 is set if capname is not defined for
this terminal type (nothing is written to standard output).
integer
a value of 0 is always set, whether or not capname is
defined for this terminal type. To determine if capname is
defined for this terminal type, the user must test the value
written to standard output. A value of -1 means that
capname is not defined for this terminal type.
other
reset or init may fail to find their respective files. In
that case, the exit code is set to 4 + errno.

@TPUT@(1) @TPUT@(1)
Any other exit code indicates an error; see the DIAGNOSTICS section.
DIAGNOSTICS
tput prints the following error messages and sets the corresponding
exit codes.
l l. exit code error message = 0 T{ (capname is a numeric variable
that is not specified in the terminfo(5) database for this terminal
type, e.g. @TPUT@ -T450 lines and @TPUT@ -T2621 xmc) T} 1 no error
message is printed, see the EXIT CODES section. 2 usage error
3 unknown terminal type or no terminfo database 4 unknown

PORTABILITY
The longname and -S options, and the parameter-substitution features
used in the cup example, are not supported in BSD curses or in
AT&T/USL curses before SVr4.
X/Open documents only the operands for clear, init and reset. In this
implementation, clear is part of the capname support. Other
implementations of tput on SVr4-based systems such as Solaris, IRIX64
and HPUX as well as others such as AIX and Tru64 provide support for
capname operands. A few platforms such as FreeBSD and NetBSD
recognize termcap names rather than terminfo capability names in their
respective tput commands.
