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 also be ignored.

       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
       /etc/terminfo
	      compiled terminal description database

       /usr/share/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 com‐
       mands.

       Most implementations which provide support for capname operands use the
       tparm  function	to  expand  parameters in it.  That function expects a
       mixture of numeric and string parameters, requiring tput to know	 which
       type  to	 use.	This implementation uses a table to determine that for
       the standard capname operands, and an internal library function to ana‐
       lyze  nonstandard  capname  operands.  Other implementations may simply
       guess that an operand containing only digits is intended to be  a  num‐
       ber.
