tput(1)                              General Commands Manual                              tput(1)

       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 terminal-dependent capa‐
       bilities 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:

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

                   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 sec‐
       tions.)  For a complete list of capabilities and the capname  associated  with  each,  see

       -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 also be ignored.

              indicates  the capability from the terminfo database.  When termcap support is com‐
              piled 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 exam‐
              ple).  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

              (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.

              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  ter‐
              minfo 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  vari‐
            able TERM.  This command should be included in everyone's .profile after the environ‐
            mental 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 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 terminated 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 termi‐
              nal (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 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  cap‐
                   name  is  not  defined  for this terminal type (nothing is written to standard

                   a value of 0 is always set, whether or not capname is defined for this  termi‐
                   nal 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 cap‐
                   name 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(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.

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

       The longname and -S options, and the parameter-substitution features used in the cup exam‐
       ple, 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 platforms such as FreeBSD and NetBSD recognize termcap names  rather  than  terminfo
       capability names in their respective tput commands.

       Most  implementations which provide support for capname operands use the tparm function to
       expand parameters in it.  That function expects a mixture of numeric  and  string  parame‐
       ters,  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 function to ana‐
       lyze nonstandard capname operands.  Other implementations may simply guess that an operand
       containing only digits is intended to be a number.

       clear(1), stty(1), tabs(1), terminfo(5), termcap(3NCURSES).

       This describes ncurses version 5.9 (patch 20140913).
