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 ter‐
       minal-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 capa‐
       bility'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	unnec‐
	      essary,  because the default is taken from the environment vari‐
	      able 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 term‐
	      cap  support is compiled in, the termcap name for the capability
	      is also accepted.

       parms  If the capability is a string that takes parameters,  the	 argu‐
	      ments parms will be instantiated into the string.

	      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 cap‐
	      name 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	 data‐
	      base [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 termi‐
	    nal.  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 <<!
	    > clear
	    > cup 10 10
	    > bold
	    > !

	    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	termi‐
	    nated by an exclamation mark (!) on a line by itself.

FILES
       /usr/share/terminfo
	      compiled terminal description database

       /resources/NCurses/data/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 cap‐
       name:

	    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 ter‐
		   minal  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.

       Any other exit code indicates an error; see the DIAGNOSTICS section.

DIAGNOSTICS
       tput prints the following error messages	 and  sets  the	 corresponding
       exit codes.

       exit code   error message
       ─────────────────────────────────────────────────────────────────────
       0	   (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)
       1	   no error message is printed, see the EXIT CODES section.
       2	   usage error
       3	   unknown terminal type or no terminfo database
       4	   unknown terminfo capability capname
       >4	   error occurred in -S
       ─────────────────────────────────────────────────────────────────────

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  implemen‐
       tations	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 op‐
       erands.	 A  few platforms such as FreeBSD and NetBSD recognize termcap
       names rather than terminfo capability names in  their  respective  tput
       commands.

SEE ALSO
       clear(1), stty(1), tabs(1), terminfo(5).

       This describes ncurses version 5.7 (patch 20081102).
