NAME

       tput - initialize a terminal or query terminfo database

SYNOPSIS

       tput [-T type] capname [parm]...

       tput -S <<

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 clear, initialize or reset the terminal; or to return the long name of the requested terminal type. tput outputs  a  string
       if  the	capability  attribute  (capname) 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 status (0 for TRUE if the terminal has the capability, 1 for FALSE if it does not), and produces no out-
       put.  Before  using  a  value returned on standard output, the user should test the exit status ($?, see sh(1)) to be sure it is 0. See the
       EXIT STATUS section.

OPTIONS

       The following options are supported:

       -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 and the layer size will not be referenced.

       -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 the example in the EXAMPLES section). Only one capname is allowed per line. The -S option  changes
		  the meaning of the 0 and 1 boolean and string exit statuses (see the EXAMPLES section).

OPERANDS

       The following operands are supported:

       capname	   Indicates the capability attribute from the terminfo database. See terminfo(4) for a complete list of capabilities and the cap-
		   name associated with each.

		   The following strings will be supported as operands by the implementation in the "C" locale:

		   clear	Display the clear-screen sequence.

		   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 (for instance, 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 descrip-
				tion in the terminfo database (see term(5)).

       parm	   If the attribute is a string that takes parameters, the argument parm will be instantiated into  the  string.  An  all  numeric
		   argument will be passed to the attribute as a number.

EXAMPLES

       Example 1 Initializing the terminal according to TERM

       This  example  initializes the terminal according to the type of terminal in the environment variable TERM. This command should be included
       in everyone's .profile after the environment variable TERM has been exported, as illustrated on the profile(4) manual page.

	 example% tput init

       Example 2 Resetting a terminal

       This example resets an AT&T 5620 terminal, overriding the type of terminal in the environment variable TERM:

	 example% tput -T5620 reset

       Example 3 Moving the cursor

       The following example sends 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).

	 example% tput cup 0 0

       This next example sends the sequence to move the cursor to row 23, column 4.

	 example% tput cup 23 4

       Example 4 Echoing the clear-screen sequence

       This example echos the clear-screen sequence for the current terminal.

	 example% tput clear

       Example 5 Printing the number of columns

       This command prints the number of columns for the current terminal.

	 example% tput cols

       The following command prints the number of columns for the 450 terminal.

	 example% tput -T450 cols

       Example 6 Setting shell variables

       This  example  sets 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"
	 example% bold='tput smso'
	 example% offbold='tput rmso'

       Example 7 Setting the exit status

       This example sets the exit status to indicate if the current terminal is a hardcopy terminal.

	 example% tput hc

       Example 8 Printing the long name from terminfo

       This command prints the long name from the terminfo database for the type of terminal specified in the environment variable TERM.

	 example% tput longname

       Example 9 Processing several capabilities with one invocation

       This example shows tput processing several capabilities in one invocation. This example 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.

	 example% tput -S <<!
	 > clear
	 > cup 10 10
	 > bold
	 > !

ENVIRONMENT VARIABLES

       See  environ(5)	for descriptions of the following environment variables that affect the execution of tput: LANG, LC_ALL, LC_CTYPE, LC_MES-
       SAGES, and NLSPATH.

       TERM	Determine the terminal type. If this variable is unset or null, and if the -T option is not specified, an unspecified default ter-
		minal type will be used.

EXIT STATUS

       The following exit values are returned:

       0
		     o	    If capname is of type boolean and -S is not specified, indicates TRUE.

		     o	    If capname is of type string and -S is not specified, indicates capname is defined for this terminal type.

		     o	    If capname is of type boolean or string and -S is specified, indicates that all lines were successful.

		     o	    capname is of type integer.

		     o	    The requested string was written successfully.

       1
		     o	    If capname is of type boolean and -S is not specified, indicates FALSE.

		     o	    If capname is of type string and -S is not specified, indicates that capname is not defined for this terminal type.

       2	 Usage error.

       3	 No information is available about the specified terminal type.

       4	 The specified operand is invalid.

       >4	 An error occurred.

       -1	 capname is a numeric variable that is not specified in the terminfo database. For instance, tput -T450 lines and tput -T2621 xmc.
