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.  tput outputs	a  string  if  the
       attribute  (capability  name)  is  of type string, or an integer if the attribute is of type integer.  If the attribute is of type boolean,
       tput simply sets the exit code (0 for TRUE if the terminal has the capability, 1 for FALSE if it does not), and produces no output.  Before
       using  a value returned on standard output, the user should test the exit code [$?, 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(1).

       -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 attribute from the terminfo database.  When termcap support is compiled in, the termcap name for the attribute is also
	      accepted.

       parms  If  the attribute is a string that takes parameters, the arguments parms will be instantiated into the string.  An all-numeric argu-
	      ment will be passed to the attribute as a number.

	      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 attribute, tput writes the string without perform-
	      ing 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 bool-
	      ean 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 (is1, is2, is3, if, iprog), (2) any delays (e.g.,  newline)  speci-
	      fied  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 termi-
	      nal 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 posi-
	    tion).

       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 <<!
	    > 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 terminated by an exclamation mark (!) on a line by itself.

FILES

       /usr/share/terminfo
	      compiled terminal description database

       /usr/include/curses.h
	      curses(3X) header file

       /usr/include/term.h
	      terminfo header file

       /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 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.

       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(1)  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.
