21 <H2>DESCRIPTION</H2><PRE>
22 The <B>tput</B> utility uses the <B>terminfo</B> database to make the
23 values of terminal-dependent capabilities and information
24 available to the shell (see <B><A HREF="sh.1.html">sh(1)</A></B>), to initialize or reset
25 the terminal, or return the long name of the requested
26 terminal type. <B>tput</B> outputs a string if the attribute
27 (<I>cap</I>ability <I>name</I>) is of type string, or an integer if the
28 attribute is of type integer. If the attribute is of type
29 boolean, <B>tput</B> simply sets the exit code (<B>0</B> for TRUE if the
30 terminal has the capability, <B>1</B> for FALSE if it does not),
31 and produces no output. Before using a value returned on
32 standard output, the user should test the exit code [<B>$?</B>,
33 see <B><A HREF="sh.1.html">sh(1)</A></B>] to be sure it is <B>0</B>. (See the <B>EXIT</B> <B>CODES</B> and
34 <B>DIAGNOSTICS</B> sections.) For a complete list of capabili-
35 ties and the <I>capname</I> associated with each, see <B>ter-</B>
36 <B><A HREF="minfo.5.html">minfo(5)</A></B>.
38 <B>-T</B><I>type</I> indicates the <I>type</I> of terminal. Normally this
39 option is unnecessary, because the default is taken
40 from the environment variable <B>TERM</B>. If <B>-T</B> is spec-
41 ified, then the shell variables <B>LINES</B> and <B>COLUMNS</B>
42 will be ignored,and the operating system will not
43 be queried for the actual screen size.
46 indicates the attribute from the <B>terminfo</B> database.
47 When <B>termcap</B> support is compiled in, the <B>termcap</B>
48 name for the attribute is also accepted.
50 <I>parms</I> If the attribute is a string that takes parameters,
51 the arguments <I>parms</I> will be instantiated into the
52 string. An all numeric argument will be passed to
53 the attribute as a number.
55 <B>-S</B> allows more than one capability per invocation of
56 <B>tput</B>. The capabilities must be passed to <B>tput</B> from
57 the standard input instead of from the command line
58 (see example). Only one <I>capname</I> is allowed per
59 line. The <B>-S</B> option changes the meaning of the <B>0</B>
60 and <B>1</B> boolean and string exit codes (see the EXIT
63 <B>init</B> If the <B>terminfo</B> database is present and an entry
64 for the user's terminal exists (see <B>-T</B><I>type</I>, above),
65 the following will occur: (1) if present, the ter-
66 minal's initialization strings will be output (<B>is1</B>,
67 <B>is2</B>, <B>is3</B>, <B>if</B>, <B>iprog</B>), (2) any delays (e.g., new-
68 line) specified in the entry will be set in the tty
69 driver, (3) tabs expansion will be turned on or off
70 according to the specification in the entry, and
71 (4) if tabs are not expanded, standard tabs will be
72 set (every 8 spaces). If an entry does not contain
73 the information needed for any of the four above
74 activities, that activity will silently be skipped.
76 <B>reset</B> Instead of putting out initialization strings, the
77 terminal's reset strings will be output if present
78 (<B>rs1</B>, <B>rs2</B>, <B>rs3</B>, <B>rf</B>). If the reset strings are not
79 present, but initialization strings are, the ini-
80 tialization strings will be output. Otherwise,
81 <B>reset</B> acts identically to <B>init</B>.
84 If the <B>terminfo</B> database is present and an entry
85 for the user's terminal exists (see <B>-T</B><I>type</I> above),
86 then the long name of the terminal will be put out.
87 The long name is the last name in the first line of
88 the terminal's description in the <B>terminfo</B> database
89 [see <B><A HREF="term.5.html">term(5)</A></B>].
93 <H2>EXAMPLES</H2><PRE>
94 <B>tput</B> <B>init</B>
95 Initialize the terminal according to the type of ter-
96 minal in the environmental variable <B>TERM</B>. This com-
97 mand should be included in everyone's .profile after
98 the environmental variable <B>TERM</B> has been exported, as
99 illustrated on the <B><A HREF="profile.4.html">profile(4)</A></B> manual page.
101 <B>tput</B> <B>-T5620</B> <B>reset</B>
102 Reset an AT&T 5620 terminal, overriding the type of
103 terminal in the environmental variable <B>TERM</B>.
105 <B>tput</B> <B>cup</B> <B>0</B> <B>0</B>
106 Send the sequence to move the cursor to row <B>0</B>, column
107 <B>0</B> (the upper left corner of the screen, usually known
108 as the "home" cursor position).
110 <B>tput</B> <B>clear</B>
111 Echo the clear-screen sequence for the current termi-
114 <B>tput</B> <B>cols</B>
115 Print the number of columns for the current terminal.
117 <B>tput</B> <B>-T450</B> <B>cols</B>
118 Print the number of columns for the 450 terminal.
121 <B>bold=`tput</B> <B>smso`</B> <B>offbold=`tput</B> <B>rmso`</B>
122 Set the shell variables <B>bold</B>, to begin stand-out mode
123 sequence, and <B>offbold</B>, to end standout mode sequence,
124 for the current terminal. This might be followed by
125 a prompt: <B>echo</B> <B>"${bold}Please</B> <B>type</B> <B>in</B> <B>your</B> <B>name:</B>
128 <B>tput</B> <B>hc</B>
129 Set exit code to indicate if the current terminal is
130 a hard copy terminal.
132 <B>tput</B> <B>cup</B> <B>23</B> <B>4</B>
133 Send the sequence to move the cursor to row 23, col-
136 <B>tput</B> <B>longname</B>
137 Print the long name from the <B>terminfo</B> database for
138 the type of terminal specified in the environmental
139 variable <B>TERM</B>.
141 <B>tput</B> <B>-S</B> <B><<!</B>
142 <B>></B> <B>clear</B>
143 <B>></B> <B>cup</B> <B>10</B> <B>10</B>
144 <B>></B> <B>bold</B>
147 This example shows tput processing several capabili-
148 ties in one invocation. This example clears the
149 screen, moves the cursor to position 10, 10 and turns
150 on bold (extra bright) mode. The list is terminated
151 by an exclamation mark (<B>!</B>) on a line by itself.

181 <H2>EXIT CODES</H2><PRE>
182 If <I>capname</I> is of type boolean, a value of <B>0</B> is set for
183 TRUE and <B>1</B> for FALSE unless the <B>-S</B> option is used.
185 If <I>capname</I> is of type string, a value of <B>0</B> is set if the
186 <I>capname</I> is defined for this terminal <I>type</I> (the value of
187 <I>capname</I> is returned on standard output); a value of <B>1</B> is
188 set if <I>capname</I> is not defined for this terminal <I>type</I> (a
189 null value is returned on standard output).
191 If <I>capname</I> is of type boolean or string and the <B>-S</B> option
192 is used, a value of <B>0</B> is returned to indicate that all
193 lines were successful. No indication of which line failed
194 can be given so exit code <B>1</B> will never appear. Exit codes
195 <B>2</B>, <B>3</B>, and <B>4</B> retain their usual interpretation.
197 If <I>capname</I> is of type integer, a value of <B>0</B> is always set,
198 whether or not <I>capname</I> is defined for this terminal <I>type</I>.
199 To determine if <I>capname</I> is defined for this terminal <I>type</I>,
200 the user must test the value of standard output. A value
201 of <B>-1</B> means that <I>capname</I> is not defined for this terminal
204 Any other exit code indicates an error; see the DIAGNOS-
209 <H2>DIAGNOSTICS</H2><PRE>
210 <B>tput</B> prints the following error messages and sets the cor-
211 responding exit codes.
213 exit code error message
214 <B>0</B> (<I>capname</I> is a numeric variable that is not specified in the
215 <B><A HREF="terminfo.5.html">terminfo(5)</A></B> database for this terminal type, e.g.
216 <B>tput</B> <B>-T450</B> <B>lines</B> and <B>tput</B> <B>-T2621</B> <B>xmc</B>)
217 <B>1</B> no error message is printed, see the <B>EXIT</B> <B>CODES</B> section.

224 <H2>PORTABILITY</H2><PRE>
225 The <B>longname</B> and <B>-S</B> options, and the parameter-substitu-
226 tion features used in the <B>cup</B> example, are not supported
227 in BSD curses or in AT&T/USL curses before SVr4.
