  66 <H2>DESCRIPTION</H2><PRE>
  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><A HREF="sh.1.html">sh(1)</A></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><A HREF="sh.1.html">sh(1)</A></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 be ignored,and the operating system  will  not
  99               be queried for the actual screen size.
 100
 101        <EM>capname</EM>
 102               indicates   the   capability   from   the  <STRONG>terminfo</STRONG>
 103               database.  When <STRONG>termcap</STRONG> support is compiled in, the
 104               <STRONG>termcap</STRONG> name for the capability is also accepted.
 105
 106        <EM>parms</EM>  If  the  capability  is a string that takes parame-
 107               ters, the arguments <EM>parms</EM> will be instantiated into
 108               the string.
 109
 110               Most  parameters  are numbers.  Only a few terminfo
 111               capabilities require string parameters; <STRONG>tput</STRONG> uses a
 112               table to decide which to pass as strings.  Normally
 113               <STRONG>tput</STRONG> uses <STRONG>tparm</STRONG> (3x) to perform  the  substitution.
 114               If no parameters are given for the capability, <STRONG>tput</STRONG>
 115               writes   the   string   without   performing    the
 116               substitution.
 117
 118        <STRONG>-S</STRONG>     allows  more  than one capability per invocation of
 119               <STRONG>tput</STRONG>.  The capabilities must be passed to <STRONG>tput</STRONG> from
 120               the standard input instead of from the command line
 121               (see example).  Only one  <EM>capname</EM>  is  allowed  per
 122               line.   The  <STRONG>-S</STRONG> option changes the meaning of the <STRONG>0</STRONG>
 123               and <STRONG>1</STRONG> boolean and string exit codes (see  the  EXIT
 124               CODES section).
 125
 126               Again, <STRONG>tput</STRONG> uses a table and the presence of param-
 127               eters in its input to decide whether to  use  <STRONG>tparm</STRONG>
 128               (3x), and how to interpret the parameters.
 129
 130        <STRONG>-V</STRONG>     reports  the  version  of ncurses which was used in
 131               this program, and exits.
 132
 133        <STRONG>init</STRONG>   If the <STRONG>terminfo</STRONG> database is present  and  an  entry
 134               for the user's terminal exists (see <STRONG>-T</STRONG><EM>type</EM>, above),
 135               the following will occur:
 136
 137               (1)    if present,  the  terminal's  initialization
 138                      strings  will  be  output as detailed in the
 139                      <STRONG><A HREF="terminfo.5.html">terminfo(5)</A></STRONG> section on <EM>Tabs</EM> <EM>and</EM>  <EM>Initializa-</EM>
 140                      <EM>tion</EM>,
 141
 142               (2)    any  delays (e.g., newline) specified in the
 143                      entry will be set in the tty driver,
 144
 145               (3)    tabs expansion will  be  turned  on  or  off
 146                      according to the specification in the entry,
 147                      and
 148
 149               (4)    if tabs are not expanded, standard tabs will
 150                      be set (every 8 spaces).
 151
 152               If an entry does not contain the information needed
 153               for any of the four above activities, that activity
 154               will silently be skipped.
 155
 156        <STRONG>reset</STRONG>  Instead  of putting out initialization strings, the
 157               terminal's reset strings will be output if  present
 158               (<STRONG>rs1</STRONG>,  <STRONG>rs2</STRONG>, <STRONG>rs3</STRONG>, <STRONG>rf</STRONG>).  If the reset strings are not
 159               present, but initialization strings are,  the  ini-
 160               tialization  strings  will  be  output.  Otherwise,
 161               <STRONG>reset</STRONG> acts identically to <STRONG>init</STRONG>.
 162
 163        <STRONG>longname</STRONG>
 164               If the <STRONG>terminfo</STRONG> database is present  and  an  entry
 165               for  the user's terminal exists (see <STRONG>-T</STRONG><EM>type</EM> above),
 166               then the long name of the terminal will be put out.
 167               The long name is the last name in the first line of
 168               the terminal's description in the <STRONG>terminfo</STRONG> database
 169               [see <STRONG><A HREF="term.5.html">term(5)</A></STRONG>].
 170
 171        If  <STRONG>tput</STRONG>  is  invoked  by a link named <STRONG>reset</STRONG>, this has the
 172        same effect as <STRONG>tput</STRONG> <STRONG>reset</STRONG>.  See <STRONG>tset</STRONG> for comparison, which
 173        has similar behavior.

 177 <H2>EXAMPLES</H2><PRE>
 178        <STRONG>tput</STRONG> <STRONG>init</STRONG>
 179             Initialize the terminal according to the type of ter-
 180             minal in the environmental variable <STRONG>TERM</STRONG>.  This  com-
 181             mand  should be included in everyone's .profile after
 182             the environmental variable <STRONG>TERM</STRONG> has been exported, as
 183             illustrated on the <STRONG><A HREF="profile.5.html">profile(5)</A></STRONG> manual page.
 184
 185        <STRONG>tput</STRONG> <STRONG>-T5620</STRONG> <STRONG>reset</STRONG>
 186             Reset  an  AT&amp;T 5620 terminal, overriding the type of
 187             terminal in the environmental variable <STRONG>TERM</STRONG>.
 188
 189        <STRONG>tput</STRONG> <STRONG>cup</STRONG> <STRONG>0</STRONG> <STRONG>0</STRONG>
 190             Send the sequence to move the cursor to row <STRONG>0</STRONG>, column
 191             <STRONG>0</STRONG> (the upper left corner of the screen, usually known
 192             as the "home" cursor position).
 193
 194        <STRONG>tput</STRONG> <STRONG>clear</STRONG>
 195             Echo the clear-screen sequence for the current termi-
 196             nal.
 197
 198        <STRONG>tput</STRONG> <STRONG>cols</STRONG>
 199             Print the number of columns for the current terminal.
 200
 201        <STRONG>tput</STRONG> <STRONG>-T450</STRONG> <STRONG>cols</STRONG>
 202             Print the number of columns for the 450 terminal.
 203
 204        <STRONG>bold=`tput</STRONG> <STRONG>smso`</STRONG> <STRONG>offbold=`tput</STRONG> <STRONG>rmso`</STRONG>
 205             Set the shell variables <STRONG>bold</STRONG>, to begin stand-out mode
 206             sequence, and <STRONG>offbold</STRONG>, to end standout mode sequence,
 207             for the current terminal.  This might be followed  by
 208             a  prompt:  <STRONG>echo</STRONG>  <STRONG>"${bold}Please</STRONG>  <STRONG>type</STRONG>  <STRONG>in</STRONG> <STRONG>your</STRONG> <STRONG>name:</STRONG>
 209             <STRONG>${offbold}\c"</STRONG>
 210
 211        <STRONG>tput</STRONG> <STRONG>hc</STRONG>
 212             Set exit code to indicate if the current terminal  is
 213             a hard copy terminal.
 214
 215        <STRONG>tput</STRONG> <STRONG>cup</STRONG> <STRONG>23</STRONG> <STRONG>4</STRONG>
 216             Send  the sequence to move the cursor to row 23, col-
 217             umn 4.
 218
 219        <STRONG>tput</STRONG> <STRONG>cup</STRONG>
 220             Send the terminfo string for cursor-movement, with no
 221             parameters substituted.
 222
 223        <STRONG>tput</STRONG> <STRONG>longname</STRONG>
 224             Print  the  long  name from the <STRONG>terminfo</STRONG> database for
 225             the type of terminal specified in  the  environmental
 226             variable <STRONG>TERM</STRONG>.

 233
 234             This  example shows <STRONG>tput</STRONG> processing several capabili-
 235             ties in one invocation.  It clears the screen,  moves
 236             the  cursor  to  position  10,  10  and turns on bold
 237             (extra bright) mode.  The list is  terminated  by  an
 238             exclamation mark (<STRONG>!</STRONG>) on a line by itself.

 255 <H2>EXIT CODES</H2><PRE>
 256        If the <STRONG>-S</STRONG> option is used, <STRONG>tput</STRONG> checks for errors from each
 257        line, and if any errors are found, will set the exit  code
 258        to  4  plus the number of lines with errors.  If no errors
 259        are found, the exit code is <STRONG>0</STRONG>.   No  indication  of  which
 260        line failed can be given so exit code <STRONG>1</STRONG> will never appear.
 261        Exit codes <STRONG>2</STRONG>, <STRONG>3</STRONG>, and <STRONG>4</STRONG> retain their usual  interpretation.
 262        If the <STRONG>-S</STRONG> option is not used, the exit code depends on the
 263        type of <EM>capname</EM>:
 264
 265             <EM>boolean</EM>
 266                    a value of <STRONG>0</STRONG> is set for TRUE and <STRONG>1</STRONG> for  FALSE.
 267
 268             <EM>string</EM> a  value of <STRONG>0</STRONG> is set if the <EM>capname</EM> is defined
 269                    for this terminal <EM>type</EM> (the value  of  <EM>capname</EM>
 270                    is  returned on standard output); a value of <STRONG>1</STRONG>
 271                    is set if <EM>capname</EM> is not defined for this ter-
 272                    minal  <EM>type</EM>  (nothing  is  written to standard
 273                    output).
 274
 275             <EM>integer</EM>
 276                    a value of <STRONG>0</STRONG> is always  set,  whether  or  not
 277                    <EM>capname</EM> is defined for this terminal <EM>type</EM>.  To
 278                    determine if <EM>capname</EM> is defined for this  ter-
 279                    minal <EM>type</EM>, the user must test the value writ-
 280                    ten to standard output.  A value of  <STRONG>-1</STRONG>  means
 281                    that  <EM>capname</EM> is not defined for this terminal
 282                    <EM>type</EM>.
 283

 313        The <STRONG>longname</STRONG> and <STRONG>-S</STRONG> options, and  the  parameter-substitu-
 314        tion  features  used in the <STRONG>cup</STRONG> example, are not supported
 315        in BSD curses or in AT&amp;T/USL curses before SVr4.
 316
 317        X/Open documents only the operands  for  <STRONG>clear</STRONG>,  <STRONG>init</STRONG>  and
 318        <STRONG>reset</STRONG>.   In this implementation, <STRONG>clear</STRONG> is part of the <EM>cap-</EM>
 319        <EM>name</EM> support.  Other implementations of <STRONG>tput</STRONG> on SVr4-based
 320        systems such as Solaris, IRIX64 and HPUX as well as others
 321        such  as  AIX  and  Tru64  provide  support  for   <EM>capname</EM>
 322        operands.  A few platforms such as FreeBSD and NetBSD rec-
 323        ognize termcap names rather than terminfo capability names
 324        in their respective <STRONG>tput</STRONG> commands.
