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
75 <STRONG>tput</STRONG> writes the string to the standard output.
76 No trailing newline is supplied.
79 <STRONG>tput</STRONG> writes the decimal value to the standard
80 output, with a trailing newline.
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
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.1.html">terminfo(1)</A></STRONG>.
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.
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.
106 <EM>parms</EM> If the capability is a string that takes parame-
107 ters, the arguments <EM>parms</EM> will be instantiated into
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
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
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.
130 <STRONG>-V</STRONG> reports the version of ncurses which was used in
131 this program, and exits.
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: (1) if present, the ter-
136 minal's initialization strings will be output (<STRONG>is1</STRONG>,
137 <STRONG>is2</STRONG>, <STRONG>is3</STRONG>, <STRONG>if</STRONG>, <STRONG>iprog</STRONG>), (2) any delays (e.g., new-
138 line) specified in the entry will be set in the tty
139 driver, (3) tabs expansion will be turned on or off
140 according to the specification in the entry, and
141 (4) if tabs are not expanded, standard tabs will be
142 set (every 8 spaces). If an entry does not contain
143 the information needed for any of the four above
144 activities, that activity will silently be skipped.
146 <STRONG>reset</STRONG> Instead of putting out initialization strings, the
147 terminal's reset strings will be output if present
148 (<STRONG>rs1</STRONG>, <STRONG>rs2</STRONG>, <STRONG>rs3</STRONG>, <STRONG>rf</STRONG>). If the reset strings are not
149 present, but initialization strings are, the ini-
150 tialization strings will be output. Otherwise,
151 <STRONG>reset</STRONG> acts identically to <STRONG>init</STRONG>.
153 <STRONG>longname</STRONG>
154 If the <STRONG>terminfo</STRONG> database is present and an entry
155 for the user's terminal exists (see <STRONG>-T</STRONG><EM>type</EM> above),
156 then the long name of the terminal will be put out.
157 The long name is the last name in the first line of
158 the terminal's description in the <STRONG>terminfo</STRONG> database
159 [see <STRONG><A HREF="term.5.html">term(5)</A></STRONG>].
161 If <STRONG>tput</STRONG> is invoked by a link named <STRONG>reset</STRONG>, this has the
162 same effect as <STRONG>tput</STRONG> <STRONG>reset</STRONG>. See <STRONG>tset</STRONG> for comparison, which
163 has similar behavior.
167 <H2>EXAMPLES</H2><PRE>
168 <STRONG>tput</STRONG> <STRONG>init</STRONG>
169 Initialize the terminal according to the type of ter-
170 minal in the environmental variable <STRONG>TERM</STRONG>. This com-
171 mand should be included in everyone's .profile after
172 the environmental variable <STRONG>TERM</STRONG> has been exported, as
173 illustrated on the <STRONG><A HREF="profile.5.html">profile(5)</A></STRONG> manual page.
175 <STRONG>tput</STRONG> <STRONG>-T5620</STRONG> <STRONG>reset</STRONG>
176 Reset an AT&T 5620 terminal, overriding the type of
177 terminal in the environmental variable <STRONG>TERM</STRONG>.
179 <STRONG>tput</STRONG> <STRONG>cup</STRONG> <STRONG>0</STRONG> <STRONG>0</STRONG>
180 Send the sequence to move the cursor to row <STRONG>0</STRONG>, column
181 <STRONG>0</STRONG> (the upper left corner of the screen, usually known
182 as the "home" cursor position).
184 <STRONG>tput</STRONG> <STRONG>clear</STRONG>
185 Echo the clear-screen sequence for the current termi-
188 <STRONG>tput</STRONG> <STRONG>cols</STRONG>
189 Print the number of columns for the current terminal.
191 <STRONG>tput</STRONG> <STRONG>-T450</STRONG> <STRONG>cols</STRONG>
192 Print the number of columns for the 450 terminal.
194 <STRONG>bold=`tput</STRONG> <STRONG>smso`</STRONG> <STRONG>offbold=`tput</STRONG> <STRONG>rmso`</STRONG>
195 Set the shell variables <STRONG>bold</STRONG>, to begin stand-out mode
196 sequence, and <STRONG>offbold</STRONG>, to end standout mode sequence,
197 for the current terminal. This might be followed by
198 a prompt: <STRONG>echo</STRONG> <STRONG>"${bold}Please</STRONG> <STRONG>type</STRONG> <STRONG>in</STRONG> <STRONG>your</STRONG> <STRONG>name:</STRONG>
199 <STRONG>${offbold}\c"</STRONG>
201 <STRONG>tput</STRONG> <STRONG>hc</STRONG>
202 Set exit code to indicate if the current terminal is
203 a hard copy terminal.
205 <STRONG>tput</STRONG> <STRONG>cup</STRONG> <STRONG>23</STRONG> <STRONG>4</STRONG>
206 Send the sequence to move the cursor to row 23, col-
209 <STRONG>tput</STRONG> <STRONG>cup</STRONG>
210 Send the terminfo string for cursor-movement, with no
211 parameters substituted.
213 <STRONG>tput</STRONG> <STRONG>longname</STRONG>
214 Print the long name from the <STRONG>terminfo</STRONG> database for
215 the type of terminal specified in the environmental
216 variable <STRONG>TERM</STRONG>.
218 <STRONG>tput</STRONG> <STRONG>-S</STRONG> <STRONG><<!</STRONG>
219 <STRONG>></STRONG> <STRONG>clear</STRONG>
220 <STRONG>></STRONG> <STRONG>cup</STRONG> <STRONG>10</STRONG> <STRONG>10</STRONG>
221 <STRONG>></STRONG> <STRONG>bold</STRONG>
222 <STRONG>></STRONG> <STRONG>!</STRONG>
224 This example shows <STRONG>tput</STRONG> processing several capabili-
225 ties in one invocation. It clears the screen, moves
226 the cursor to position 10, 10 and turns on bold
227 (extra bright) mode. The list is terminated by an
228 exclamation mark (<STRONG>!</STRONG>) on a line by itself.
233 <STRONG>/usr/share/terminfo</STRONG>
234 compiled terminal description database
236 <STRONG>/usr/share/tabset/*</STRONG>
237 tab settings for some terminals, in a format appro-
238 priate to be output to the terminal (escape
239 sequences that set margins and tabs); for more
240 information, see the "Tabs and Initialization" sec-
241 tion of <STRONG><A HREF="terminfo.5.html">terminfo(5)</A></STRONG>
245 <H2>EXIT CODES</H2><PRE>
246 If the <STRONG>-S</STRONG> option is used, <STRONG>tput</STRONG> checks for errors from each
247 line, and if any errors are found, will set the exit code
248 to 4 plus the number of lines with errors. If no errors
249 are found, the exit code is <STRONG>0</STRONG>. No indication of which
250 line failed can be given so exit code <STRONG>1</STRONG> will never appear.
251 Exit codes <STRONG>2</STRONG>, <STRONG>3</STRONG>, and <STRONG>4</STRONG> retain their usual interpretation.
252 If the <STRONG>-S</STRONG> option is not used, the exit code depends on the
253 type of <EM>capname</EM>:
256 a value of <STRONG>0</STRONG> is set for TRUE and <STRONG>1</STRONG> for FALSE.
258 <EM>string</EM> a value of <STRONG>0</STRONG> is set if the <EM>capname</EM> is defined
259 for this terminal <EM>type</EM> (the value of <EM>capname</EM>
260 is returned on standard output); a value of <STRONG>1</STRONG>
261 is set if <EM>capname</EM> is not defined for this ter-
262 minal <EM>type</EM> (nothing is written to standard
266 a value of <STRONG>0</STRONG> is always set, whether or not
267 <EM>capname</EM> is defined for this terminal <EM>type</EM>. To
268 determine if <EM>capname</EM> is defined for this ter-
269 minal <EM>type</EM>, the user must test the value writ-
270 ten to standard output. A value of <STRONG>-1</STRONG> means
271 that <EM>capname</EM> is not defined for this terminal
274 <EM>other</EM> <STRONG>reset</STRONG> or <STRONG>init</STRONG> may fail to find their respec-
275 tive files. In that case, the exit code is
276 set to 4 + <STRONG>errno</STRONG>.
278 Any other exit code indicates an error; see the DIAGNOS-
283 <H2>DIAGNOSTICS</H2><PRE>
284 <STRONG>tput</STRONG> prints the following error messages and sets the cor-
285 responding exit codes.
