Amit Daniel Kachhape6a01f52011-07-20 11:45:59 +053067 The <STRONG>tput</STRONG> utility uses the <STRONG>terminfo</STRONG> database to make the
68 values of terminal-dependent capabilities and information
Steve Kondikae271bc2015-11-15 02:50:53 +010069 available to the shell (see <STRONG>sh(1)</STRONG>), to initialize or reset
Amit Daniel Kachhape6a01f52011-07-20 11:45:59 +053070 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
Steve Kondikae271bc2015-11-15 02:50:53 +010090 <STRONG>sh(1)</STRONG>) to be sure it is <STRONG>0</STRONG>. (See the <STRONG>EXIT</STRONG> <STRONG>CODES</STRONG> and <STRONG>DIAG-</STRONG>
Amit Daniel Kachhape6a01f52011-07-20 11:45:59 +053091 <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>
Steve Kondikae271bc2015-11-15 02:50:53 +010098 will also be ignored.
Amit Daniel Kachhape6a01f52011-07-20 11:45:59 +053099
100 <EM>capname</EM>
Steve Kondikae271bc2015-11-15 02:50:53 +0100101 indicates the capability from the <STRONG>terminfo</STRONG> data-
102 base. When <STRONG>termcap</STRONG> support is compiled in, the
Amit Daniel Kachhape6a01f52011-07-20 11:45:59 +0530103 <STRONG>termcap</STRONG> name for the capability is also accepted.
104
Steve Kondikae271bc2015-11-15 02:50:53 +0100105 <EM>parms</EM> If the capability is a string that takes parame-
Amit Daniel Kachhape6a01f52011-07-20 11:45:59 +0530106 ters, the arguments <EM>parms</EM> will be instantiated into
107 the string.
108
Steve Kondikae271bc2015-11-15 02:50:53 +0100109 Most parameters are numbers. Only a few terminfo
Amit Daniel Kachhape6a01f52011-07-20 11:45:59 +0530110 capabilities require string parameters; <STRONG>tput</STRONG> uses a
111 table to decide which to pass as strings. Normally
Steve Kondikae271bc2015-11-15 02:50:53 +0100112 <STRONG>tput</STRONG> uses <STRONG>tparm</STRONG> (3x) to perform the substitution.
Amit Daniel Kachhape6a01f52011-07-20 11:45:59 +0530113 If no parameters are given for the capability, <STRONG>tput</STRONG>
Steve Kondikae271bc2015-11-15 02:50:53 +0100114 writes the string without performing the substitu-
115 tion.
Amit Daniel Kachhape6a01f52011-07-20 11:45:59 +0530116
Steve Kondikae271bc2015-11-15 02:50:53 +0100117 <STRONG>-S</STRONG> allows more than one capability per invocation of
Amit Daniel Kachhape6a01f52011-07-20 11:45:59 +0530118 <STRONG>tput</STRONG>. The capabilities must be passed to <STRONG>tput</STRONG> from
119 the standard input instead of from the command line
Steve Kondikae271bc2015-11-15 02:50:53 +0100120 (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
Amit Daniel Kachhape6a01f52011-07-20 11:45:59 +0530123 CODES section).
124
125 Again, <STRONG>tput</STRONG> uses a table and the presence of param-
Steve Kondikae271bc2015-11-15 02:50:53 +0100126 eters in its input to decide whether to use <STRONG>tparm</STRONG>
Amit Daniel Kachhape6a01f52011-07-20 11:45:59 +0530127 (3x), and how to interpret the parameters.
128
Steve Kondikae271bc2015-11-15 02:50:53 +0100129 <STRONG>-V</STRONG> reports the version of ncurses which was used in
Amit Daniel Kachhape6a01f52011-07-20 11:45:59 +0530130 this program, and exits.
131
Steve Kondikae271bc2015-11-15 02:50:53 +0100132 <STRONG>init</STRONG> If the <STRONG>terminfo</STRONG> database is present and an entry
Amit Daniel Kachhape6a01f52011-07-20 11:45:59 +0530133 for the user's terminal exists (see <STRONG>-T</STRONG><EM>type</EM>, above),
134 the following will occur:
135
Steve Kondikae271bc2015-11-15 02:50:53 +0100136 (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>
Amit Daniel Kachhape6a01f52011-07-20 11:45:59 +0530139 <EM>tion</EM>,
140
Steve Kondikae271bc2015-11-15 02:50:53 +0100141 (2) any delays (e.g., newline) specified in the
Amit Daniel Kachhape6a01f52011-07-20 11:45:59 +0530142 entry will be set in the tty driver,
143
Steve Kondikae271bc2015-11-15 02:50:53 +0100144 (3) tabs expansion will be turned on or off
Amit Daniel Kachhape6a01f52011-07-20 11:45:59 +0530145 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
Steve Kondikae271bc2015-11-15 02:50:53 +0100155 <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,
Amit Daniel Kachhape6a01f52011-07-20 11:45:59 +0530160 <STRONG>reset</STRONG> acts identically to <STRONG>init</STRONG>.
161
162 <STRONG>longname</STRONG>
Steve Kondikae271bc2015-11-15 02:50:53 +0100163 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),
Amit Daniel Kachhape6a01f52011-07-20 11:45:59 +0530165 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
Steve Kondikae271bc2015-11-15 02:50:53 +0100170 If <STRONG>tput</STRONG> is invoked by a link named <STRONG>reset</STRONG>, this has the
Amit Daniel Kachhape6a01f52011-07-20 11:45:59 +0530171 same effect as <STRONG>tput</STRONG> <STRONG>reset</STRONG>. See <STRONG>tset</STRONG> for comparison, which
172 has similar behavior.

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
Amit Daniel Kachhape6a01f52011-07-20 11:45:59 +0530313 in BSD curses or in AT&amp;T/USL curses before SVr4.

Amit Daniel Kachhape6a01f52011-07-20 11:45:59 +0530317 <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
Steve Kondikae271bc2015-11-15 02:50:53 +0100319 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.
