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
		       capname 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 ter-
				       minal's description 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.
