       tput, reset - initialize a terminal or query terminfo database


       tput [-Ttype] capname [parms ... ]
       tput [-Ttype] init
       tput [-Ttype] reset
       tput [-Ttype] longname
       tput -S  <<
       tput -V


       The  tput utility uses the terminfo database to make the values of ter-
       minal-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 capa-
       bility’s type:

                   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 DIAGNOSTICS sections.)  For a complete list of
       capabilities and the capname associated with each, see terminfo(1).

       -Ttype indicates the type of terminal.  Normally this option is  unnec-
              essary,  because the default is taken from the environment vari-
              able 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.

              indicates the capability from the terminfo database.  When term-
              cap  support is compiled in, the termcap name for the capability
              is also accepted.

       parms  If the capability is a string that takes parameters,  the  argu-
              ments 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 cap-
              name is allowed per line.  The -S option changes the meaning  of
              the  0  and  1 boolean and string exit codes (see the EXIT CODES

              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 (is1, is2, is3, if, iprog), (2) any  delays  (e.g.,  new-
              line)  specified in the entry will be set in the tty driver, (3)
              tabs expansion will be turned on or off according to the  speci-
              fication  in  the entry, and (4) if tabs are not expanded, stan-
              dard tabs will be set (every 8 spaces).  If an  entry  does  not
              contain the information needed for any of the four above activi-
              ties, 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.

              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 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

       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 termi-
            nal.  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

       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

       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 termi-
            nated by an exclamation mark (!) on a line by itself.


              compiled terminal description database

              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)


       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  cap-

                   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 ter-
                   minal 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).

                   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.


       tput prints the following error messages  and  sets  the  corresponding
       exit codes.

       exit code   error message
       0           (capname  is a numeric variable that is not specified in
                   the terminfo(1) 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

       4           unknown terminfo capability capname
       >4          error occurred in -S


       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.
