       tput,  reset  -  initialize  a  terminal or query terminfo


       tput [-Ttype] capname [parms ... ]
       tput [-Ttype] init

       tput -V


       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

                   tput writes the string to the standard output.
                   No trailing newline is supplied.

                   tput writes the decimal value to the  standard
                   output, with a trailing newline.

                   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  DIAG-
       NOSTICS  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 spec-
              ified,  then  the shell variables LINES and COLUMNS
              will also be ignored.

              indicates the capability from  the  terminfo  data-
              base.   When  termcap  support  is compiled in, the
              termcap name for the capability is also accepted.

       parms  If the capability is a string  that  takes  parame-
              ters, 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 substitu-

       -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 param-
              eters  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 Initializa-

              (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,

              (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 ini-
              tialization strings  will  be  output.   Otherwise,
              reset acts identically to init.

              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 comparison, which
       has similar behavior.


       tput init
            Initialize the terminal according to the type of ter-
            minal  in the environmental variable TERM.  This com-
            mand 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 termi-

       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:

       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, col-
            umn 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 capabili-
            ties 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.

              priate  to  be  output  to  the  terminal   (escape
              sequences  that  set  margins  and  tabs); for more
              information, see the "Tabs and Initialization" sec-
              tion of terminfo(5)


       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:

                   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 ter-
                   minal type (nothing  is  written  to  standard

                   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 ter-
                   minal type, the user must test the value writ-
                   ten  to  standard output.  A value of -1 means
                   that capname is not defined for this  terminal

            other  reset  or  init may fail to find their respec-
                   tive files.  In that case, the  exit  code  is
                   set to 4 + errno.

       Any  other  exit code indicates an error; see the DIAGNOS-
       TICS section.


       tput prints the following error messages and sets the cor-
       responding exit codes.

                   the terminfo(5) database for this  terminal  type,  e.g.
                   tput -T450 lines and tput -T2621 xmc)

       The  longname  and -S options, and the parameter-substitu-
       tion 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  cap-
       name 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 oper-

       A few platforms such as FreeBSD and NetBSD recognize term-
       cap  names  rather than terminfo capability names in their
       respective tput commands.

       Most implementations which provide support for capname op-
       erands  use the tparm function to expand parameters in it.
       That function expects a  mixture  of  numeric  and  string
       parameters,  requiring  tput  to  know  which type to use.
       This implementation uses a table to determine that for the
       standard  capname  operands, and an internal library func-
       tion  to  analyze  nonstandard  capname  operands.   Other
       implementations  may simply guess that an operand contain-
       ing only digits is intended to be a number.
