  67        The <STRONG>tput</STRONG> utility uses the <STRONG>terminfo</STRONG> database  to  make  the
  68        values  of terminal-dependent capabilities and information
  69        available to the shell (see <STRONG>sh(1)</STRONG>), to initialize or reset
  70        the  terminal,  or  return  the long name of the requested
  71        terminal type.  The result depends upon  the  capability's
  72        type:
  73
  74               string
  75                    <STRONG>tput</STRONG> writes the string to the standard output.
  76                    No trailing newline is supplied.
  77
  78               integer
  79                    <STRONG>tput</STRONG> writes the decimal value to the  standard
  80                    output, with a trailing newline.
  81
  82               boolean
  83                    <STRONG>tput</STRONG>  simply sets the exit code (<STRONG>0</STRONG> for TRUE if
  84                    the terminal has the capability, <STRONG>1</STRONG>  for  FALSE
  85                    if  it  does  not),  and writes nothing to the
  86                    standard output.
  87
  88        Before using a value returned on the standard output,  the
  89        application  should  test  the  exit  code  (e.g., <STRONG>$?</STRONG>, see
  90        <STRONG>sh(1)</STRONG>) to be sure it is <STRONG>0</STRONG>.  (See the <STRONG>EXIT</STRONG> <STRONG>CODES</STRONG> and  <STRONG>DIAG-</STRONG>
  91        <STRONG>NOSTICS</STRONG>  sections.)   For  a complete list of capabilities
  92        and the <EM>capname</EM> associated with each, see <STRONG><A HREF="terminfo.5.html">terminfo(5)</A></STRONG>.
  93
  94        <STRONG>-T</STRONG><EM>type</EM> indicates the  <EM>type</EM>  of  terminal.   Normally  this
  95               option is unnecessary, because the default is taken
  96               from the environment variable <STRONG>TERM</STRONG>.  If <STRONG>-T</STRONG> is spec-
  97               ified,  then  the shell variables <STRONG>LINES</STRONG> and <STRONG>COLUMNS</STRONG>
  98               will also be ignored.
  99
 100        <EM>capname</EM>
 101               indicates the capability from  the  <STRONG>terminfo</STRONG>  data-
 102               base.   When  <STRONG>termcap</STRONG>  support  is compiled in, the
 103               <STRONG>termcap</STRONG> name for the capability is also accepted.
 104
 105        <EM>parms</EM>  If the capability is a string  that  takes  parame-
 106               ters, the arguments <EM>parms</EM> will be instantiated into
 107               the string.
 108
 109               Most parameters are numbers.  Only a  few  terminfo
 110               capabilities require string parameters; <STRONG>tput</STRONG> uses a
 111               table to decide which to pass as strings.  Normally
 112               <STRONG>tput</STRONG>  uses  <STRONG>tparm</STRONG> (3x) to perform the substitution.
 113               If no parameters are given for the capability, <STRONG>tput</STRONG>
 114               writes  the string without performing the substitu-
 115               tion.
 116
 117        <STRONG>-S</STRONG>     allows more than one capability per  invocation  of
 118               <STRONG>tput</STRONG>.  The capabilities must be passed to <STRONG>tput</STRONG> from
 119               the standard input instead of from the command line
 120               (see  example).   Only  one  <EM>capname</EM> is allowed per
 121               line.  The <STRONG>-S</STRONG> option changes the meaning of  the  <STRONG>0</STRONG>
 122               and  <STRONG>1</STRONG>  boolean and string exit codes (see the EXIT
 123               CODES section).
 124
 125               Again, <STRONG>tput</STRONG> uses a table and the presence of param-
 126               eters  in  its input to decide whether to use <STRONG>tparm</STRONG>
 127               (3x), and how to interpret the parameters.
 128
 129        <STRONG>-V</STRONG>     reports the version of ncurses which  was  used  in
 130               this program, and exits.
 131
 132        <STRONG>init</STRONG>   If  the  <STRONG>terminfo</STRONG>  database is present and an entry
 133               for the user's terminal exists (see <STRONG>-T</STRONG><EM>type</EM>, above),
 134               the following will occur:
 135
 136               (1)    if  present,  the  terminal's initialization
 137                      strings will be output as  detailed  in  the
 138                      <STRONG><A HREF="terminfo.5.html">terminfo(5)</A></STRONG>  section on <EM>Tabs</EM> <EM>and</EM> <EM>Initializa-</EM>
 139                      <EM>tion</EM>,
 140
 141               (2)    any delays (e.g., newline) specified in  the
 142                      entry will be set in the tty driver,
 143
 144               (3)    tabs  expansion  will  be  turned  on or off
 145                      according to the specification in the entry,
 146                      and
 147
 148               (4)    if tabs are not expanded, standard tabs will
 149                      be set (every 8 spaces).
 150
 151               If an entry does not contain the information needed
 152               for any of the four above activities, that activity
 153               will silently be skipped.
 154
 155        <STRONG>reset</STRONG>  Instead of putting out initialization strings,  the
 156               terminal's  reset strings will be output if present
 157               (<STRONG>rs1</STRONG>, <STRONG>rs2</STRONG>, <STRONG>rs3</STRONG>, <STRONG>rf</STRONG>).  If the reset strings are  not
 158               present,  but  initialization strings are, the ini-
 159               tialization strings  will  be  output.   Otherwise,
 160               <STRONG>reset</STRONG> acts identically to <STRONG>init</STRONG>.
 161
 162        <STRONG>longname</STRONG>
 163               If  the  <STRONG>terminfo</STRONG>  database is present and an entry
 164               for the user's terminal exists (see <STRONG>-T</STRONG><EM>type</EM>  above),
 165               then the long name of the terminal will be put out.
 166               The long name is the last name in the first line of
 167               the terminal's description in the <STRONG>terminfo</STRONG> database
 168               [see <STRONG><A HREF="term.5.html">term(5)</A></STRONG>].
 169
 170        If <STRONG>tput</STRONG> is invoked by a link named  <STRONG>reset</STRONG>,  this  has  the
 171        same effect as <STRONG>tput</STRONG> <STRONG>reset</STRONG>.  See <STRONG>tset</STRONG> for comparison, which
 172        has similar behavior.

 177        <STRONG>tput</STRONG> <STRONG>init</STRONG>
 178             Initialize the terminal according to the type of ter-
 179             minal  in the environmental variable <STRONG>TERM</STRONG>.  This com-
 180             mand should be included in everyone's .profile  after
 181             the environmental variable <STRONG>TERM</STRONG> has been exported, as
 182             illustrated on the <STRONG>profile(5)</STRONG> manual page.
 183
 184        <STRONG>tput</STRONG> <STRONG>-T5620</STRONG> <STRONG>reset</STRONG>
 185             Reset an AT&amp;T 5620 terminal, overriding the  type  of
 186             terminal in the environmental variable <STRONG>TERM</STRONG>.
 187
 188        <STRONG>tput</STRONG> <STRONG>cup</STRONG> <STRONG>0</STRONG> <STRONG>0</STRONG>
 189             Send the sequence to move the cursor to row <STRONG>0</STRONG>, column
 190             <STRONG>0</STRONG> (the upper left corner of the screen, usually known
 191             as the "home" cursor position).
 192
 193        <STRONG>tput</STRONG> <STRONG>clear</STRONG>
 194             Echo the clear-screen sequence for the current termi-
 195             nal.
 196
 197        <STRONG>tput</STRONG> <STRONG>cols</STRONG>
 198             Print the number of columns for the current terminal.
 199
 200        <STRONG>tput</STRONG> <STRONG>-T450</STRONG> <STRONG>cols</STRONG>
 201             Print the number of columns for the 450 terminal.
 202
 203        <STRONG>bold=`tput</STRONG> <STRONG>smso`</STRONG> <STRONG>offbold=`tput</STRONG> <STRONG>rmso`</STRONG>
 204             Set the shell variables <STRONG>bold</STRONG>, to begin stand-out mode
 205             sequence, and <STRONG>offbold</STRONG>, to end standout mode sequence,
 206             for the current terminal.  This might be followed  by
 207             a  prompt:  <STRONG>echo</STRONG>  <STRONG>"${bold}Please</STRONG>  <STRONG>type</STRONG>  <STRONG>in</STRONG> <STRONG>your</STRONG> <STRONG>name:</STRONG>
 208             <STRONG>${offbold}\c"</STRONG>
 209
 210        <STRONG>tput</STRONG> <STRONG>hc</STRONG>
 211             Set exit code to indicate if the current terminal  is
 212             a hard copy terminal.
 213
 214        <STRONG>tput</STRONG> <STRONG>cup</STRONG> <STRONG>23</STRONG> <STRONG>4</STRONG>
 215             Send  the sequence to move the cursor to row 23, col-
 216             umn 4.
 217
 218        <STRONG>tput</STRONG> <STRONG>cup</STRONG>
 219             Send the terminfo string for cursor-movement, with no
 220             parameters substituted.
 221
 222        <STRONG>tput</STRONG> <STRONG>longname</STRONG>
 223             Print  the  long  name from the <STRONG>terminfo</STRONG> database for
 224             the type of terminal specified in  the  environmental
 225             variable <STRONG>TERM</STRONG>.

 235             the  cursor  to  position  10,  10  and turns on bold
 236             (extra bright) mode.  The list is  terminated  by  an
 237             exclamation mark (<STRONG>!</STRONG>) on a line by itself.

 255        If the <STRONG>-S</STRONG> option is used, <STRONG>tput</STRONG> checks for errors from each
 256        line, and if any errors are found, will set the exit  code
 257        to  4  plus the number of lines with errors.  If no errors
 258        are found, the exit code is <STRONG>0</STRONG>.   No  indication  of  which
 259        line failed can be given so exit code <STRONG>1</STRONG> will never appear.
 260        Exit codes <STRONG>2</STRONG>, <STRONG>3</STRONG>, and <STRONG>4</STRONG> retain their usual  interpretation.
 261        If the <STRONG>-S</STRONG> option is not used, the exit code depends on the
 262        type of <EM>capname</EM>:
 263
 264             <EM>boolean</EM>
 265                    a value of <STRONG>0</STRONG> is set for TRUE and <STRONG>1</STRONG> for FALSE.
 266
 267             <EM>string</EM> a value of <STRONG>0</STRONG> is set if the <EM>capname</EM> is  defined
 268                    for  this  terminal <EM>type</EM> (the value of <EM>capname</EM>
 269                    is returned on standard output); a value of  <STRONG>1</STRONG>
 270                    is set if <EM>capname</EM> is not defined for this ter-
 271                    minal <EM>type</EM> (nothing  is  written  to  standard
 272                    output).
 273
 274             <EM>integer</EM>
 275                    a  value  of  <STRONG>0</STRONG>  is always set, whether or not
 276                    <EM>capname</EM> is defined for this terminal <EM>type</EM>.  To
 277                    determine  if <EM>capname</EM> is defined for this ter-
 278                    minal <EM>type</EM>, the user must test the value writ-
 279                    ten  to  standard output.  A value of <STRONG>-1</STRONG> means
 280                    that <EM>capname</EM> is not defined for this  terminal
 281                    <EM>type</EM>.

 311        The  <STRONG>longname</STRONG>  and <STRONG>-S</STRONG> options, and the parameter-substitu-
 312        tion features used in the <STRONG>cup</STRONG> example, are  not  supported
 313        in BSD curses or in AT&amp;T/USL curses before SVr4.
 314
 315        X/Open  documents  only  the  operands for <STRONG>clear</STRONG>, <STRONG>init</STRONG> and
 316        <STRONG>reset</STRONG>.  In this implementation, <STRONG>clear</STRONG> is part of the  <EM>cap-</EM>
 317        <EM>name</EM> support.  Other implementations of <STRONG>tput</STRONG> on SVr4-based
 318        systems such as Solaris, IRIX64 and HPUX as well as others
 319        such  as  AIX  and Tru64 provide support for <EM>capname</EM> oper-
 320        ands.
 321
 322        A few platforms such as FreeBSD and NetBSD recognize term-
 323        cap  names  rather than terminfo capability names in their
 324        respective <STRONG>tput</STRONG> commands.
 325
 326        Most implementations which provide support for <EM>capname</EM> op-
 327        erands  use the <EM>tparm</EM> function to expand parameters in it.
 328        That function expects a  mixture  of  numeric  and  string
 329        parameters,  requiring  <STRONG>tput</STRONG>  to  know  which type to use.
 330        This implementation uses a table to determine that for the
 331        standard  <EM>capname</EM>  operands, and an internal library func-
 332        tion  to  analyze  nonstandard  <EM>capname</EM>  operands.   Other
 333        implementations  may simply guess that an operand contain-
 334        ing only digits is intended to be a number.
