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.

	      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 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 as detailed in the terminfo(5) section on Tabs and Initial-
		     ization,

	      (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 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/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.

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  imple-
       mentations  of tput on SVr4-based systems such as Solaris, IRIX64 and HPUX as well as others such as AIX and Tru64 provide support for cap-
       name operands.  A few platforms such as FreeBSD and NetBSD recognize termcap names rather than terminfo capability names in  their  respec-
       tive tput commands.
