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 com-
       plete 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 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 database [see term(5)].

       If tput is invoked by a link named reset, this has the same effect as tput reset.  See tset for  com-parison, comparison,
       parison, 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  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 envi-ronmental environmental
            ronmental 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  cap-name capname
                   name  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 --------------------------------------------------------------------0
       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 --------------------------------------------------------------------PORTABILITY

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 implementations 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 operands.  A few plat-forms platforms
       forms such as FreeBSD and NetBSD recognize termcap names rather than  terminfo  capability  names  in
       their respective tput commands.
