</PRE>
<H2>DESCRIPTION</H2><PRE>
The <STRONG>tput</STRONG> utility uses the <STRONG>terminfo</STRONG> database to make the
values of terminal-dependent capabilities and information
available to the shell (see <STRONG><A HREF="sh.1.html">sh(1)</A></STRONG>), to initialize or reset
the terminal, or return the long name of the requested
terminal type. <STRONG>tput</STRONG> outputs a string if the attribute
(<EM>cap</EM>ability <EM>name</EM>) is of type string, or an integer if the
attribute is of type integer. If the attribute is of type
boolean, <STRONG>tput</STRONG> simply sets the exit code (<STRONG>0</STRONG> for TRUE if the
terminal has the capability, <STRONG>1</STRONG> for FALSE if it does not),
and produces no output. Before using a value returned on
standard output, the user should test the exit code [<STRONG>$?</STRONG>,
see <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>DIAGNOSTICS</STRONG> sections.) For a complete list of capabili-
ties and the <EM>capname</EM> associated with each, see <STRONG>ter-</STRONG>
<STRONG><A HREF="terminfo.1.html">minfo(1)</A></STRONG>.
<STRONG>-T</STRONG><EM>type</EM> indicates the <EM>type</EM> of terminal. Normally this
option is unnecessary, because the default is taken
from the environment variable <STRONG>TERM</STRONG>. If <STRONG>-T</STRONG> is spec-
ified, then the shell variables <STRONG>LINES</STRONG> and <STRONG>COLUMNS</STRONG>
will be ignored,and the operating system will not
be queried for the actual screen size.
<EM>capname</EM>
indicates the attribute from the <STRONG>terminfo</STRONG> database.
When <STRONG>termcap</STRONG> support is compiled in, the <STRONG>termcap</STRONG>
name for the attribute is also accepted.
<EM>parms</EM> If the attribute is a string that takes parameters,
the arguments <EM>parms</EM> will be instantiated into the
string. An all-numeric argument will be passed to
the attribute as a number.
Only a few terminfo capabilities require string
parameters; <STRONG>tput</STRONG> uses a table to decide which to
pass as strings. Normally <STRONG>tput</STRONG> uses <STRONG>tparm</STRONG> (3x) to
perform the substitution. If no parameters are
given for the attribute, <STRONG>tput</STRONG> writes the string
without performing the substitution.
<STRONG>-S</STRONG> allows more than one capability per invocation of
<STRONG>tput</STRONG>. The capabilities must be passed to <STRONG>tput</STRONG> from
the standard input instead of from the command line
(see example). Only one <EM>capname</EM> is allowed per
line. The <STRONG>-S</STRONG> option changes the meaning of the <STRONG>0</STRONG>
and <STRONG>1</STRONG> boolean and string exit codes (see the EXIT
CODES section).
Again, <STRONG>tput</STRONG> uses a table and the presence of param-
eters in its input to decide whether to use <STRONG>tparm</STRONG>
(3x), and how to interpret the parameters.
<STRONG>-V</STRONG> reports the version of ncurses which was used in
this program, and exits.
<STRONG>init</STRONG> If the <STRONG>terminfo</STRONG> database is present and an entry
for the user's terminal exists (see <STRONG>-T</STRONG><EM>type</EM>, above),
the following will occur: (1) if present, the ter-
minal's initialization strings will be output (<STRONG>is1</STRONG>,
<STRONG>is2</STRONG>, <STRONG>is3</STRONG>, <STRONG>if</STRONG>, <STRONG>iprog</STRONG>), (2) any delays (e.g., new-
line) specified in the entry will be set in the tty
driver, (3) tabs expansion will be turned on or off
according to the specification in the entry, and
(4) if tabs are not expanded, standard tabs will be
set (every 8 spaces). If an entry does not contain
the information needed for any of the four above
activities, that activity will silently be skipped.
<STRONG>reset</STRONG> Instead of putting out initialization strings, the
terminal's reset strings will be output if present
(<STRONG>rs1</STRONG>, <STRONG>rs2</STRONG>, <STRONG>rs3</STRONG>, <STRONG>rf</STRONG>). If the reset strings are not
present, but initialization strings are, the ini-
tialization strings will be output. Otherwise,
<STRONG>reset</STRONG> acts identically to <STRONG>init</STRONG>.
<STRONG>longname</STRONG>
If the <STRONG>terminfo</STRONG> database is present and an entry
for the user's terminal exists (see <STRONG>-T</STRONG><EM>type</EM> above),
then the long name of the terminal will be put out.
The long name is the last name in the first line of
the terminal's description in the <STRONG>terminfo</STRONG> database
[see <STRONG><A HREF="term.5.html">term(5)</A></STRONG>].
If <STRONG>tput</STRONG> is invoked by a link named <STRONG>reset</STRONG>, this has the
same effect as <STRONG>tput</STRONG> <STRONG>reset</STRONG>. See <STRONG>tset</STRONG> for comparison, which
has similar behavior.
</PRE>
<H2>EXAMPLES</H2><PRE>
<STRONG>tput</STRONG> <STRONG>init</STRONG>
Initialize the terminal according to the type of ter-
minal in the environmental variable <STRONG>TERM</STRONG>. This com-
mand should be included in everyone's .profile after
the environmental variable <STRONG>TERM</STRONG> has been exported, as
illustrated on the <STRONG><A HREF="profile.5.html">profile(5)</A></STRONG> manual page.
<STRONG>tput</STRONG> <STRONG>-T5620</STRONG> <STRONG>reset</STRONG>
Reset an AT&T 5620 terminal, overriding the type of
terminal in the environmental variable <STRONG>TERM</STRONG>.
<STRONG>tput</STRONG> <STRONG>cup</STRONG> <STRONG>0</STRONG> <STRONG>0</STRONG>
Send the sequence to move the cursor to row <STRONG>0</STRONG>, column
<STRONG>0</STRONG> (the upper left corner of the screen, usually known
as the "home" cursor position).
<STRONG>tput</STRONG> <STRONG>clear</STRONG>
Echo the clear-screen sequence for the current termi-
nal.
<STRONG>tput</STRONG> <STRONG>cols</STRONG>
Print the number of columns for the current terminal.
<STRONG>tput</STRONG> <STRONG>-T450</STRONG> <STRONG>cols</STRONG>
Print the number of columns for the 450 terminal.
<STRONG>bold=`tput</STRONG> <STRONG>smso`</STRONG> <STRONG>offbold=`tput</STRONG> <STRONG>rmso`</STRONG>
Set the shell variables <STRONG>bold</STRONG>, to begin stand-out mode
sequence, and <STRONG>offbold</STRONG>, to end standout mode sequence,
for the current terminal. This might be followed by
a prompt: <STRONG>echo</STRONG> <STRONG>"${bold}Please</STRONG> <STRONG>type</STRONG> <STRONG>in</STRONG> <STRONG>your</STRONG> <STRONG>name:</STRONG>
<STRONG>${offbold}\c"</STRONG>
<STRONG>tput</STRONG> <STRONG>hc</STRONG>
Set exit code to indicate if the current terminal is
a hard copy terminal.
<STRONG>tput</STRONG> <STRONG>cup</STRONG> <STRONG>23</STRONG> <STRONG>4</STRONG>
Send the sequence to move the cursor to row 23, col-
umn 4.
<STRONG>tput</STRONG> <STRONG>cup</STRONG>
Send the terminfo string for cursor-movement, with no
parameters substituted.
<STRONG>tput</STRONG> <STRONG>longname</STRONG>
Print the long name from the <STRONG>terminfo</STRONG> database for
the type of terminal specified in the environmental
variable <STRONG>TERM</STRONG>.
<STRONG>tput</STRONG> <STRONG>-S</STRONG> <STRONG><<!</STRONG>
<STRONG>></STRONG> <STRONG>clear</STRONG>
<STRONG>></STRONG> <STRONG>cup</STRONG> <STRONG>10</STRONG> <STRONG>10</STRONG>
<STRONG>></STRONG> <STRONG>bold</STRONG>
<STRONG>></STRONG> <STRONG>!</STRONG>
This example shows <STRONG>tput</STRONG> processing several capabili-
ties in one invocation. It clears the screen, moves
the cursor to position 10, 10 and turns on bold
(extra bright) mode. The list is terminated by an
exclamation mark (<STRONG>!</STRONG>) on a line by itself.

tion of <STRONG><A HREF="terminfo.5.html">terminfo(5)</A></STRONG>
</PRE>
<H2>EXIT CODES</H2><PRE>
If the <STRONG>-S</STRONG> option is used, <STRONG>tput</STRONG> checks for errors from each
line, and if any errors are found, will set the exit code
to 4 plus the number of lines with errors. If no errors
are found, the exit code is <STRONG>0</STRONG>. No indication of which
line failed can be given so exit code <STRONG>1</STRONG> will never appear.
Exit codes <STRONG>2</STRONG>, <STRONG>3</STRONG>, and <STRONG>4</STRONG> retain their usual interpretation.
If the <STRONG>-S</STRONG> option is not used, the exit code depends on the
type of <EM>capname</EM>:
<EM>boolean</EM>
a value of <STRONG>0</STRONG> is set for TRUE and <STRONG>1</STRONG> for FALSE.
<EM>string</EM> a value of <STRONG>0</STRONG> is set if the <EM>capname</EM> is defined
for this terminal <EM>type</EM> (the value of <EM>capname</EM>
is returned on standard output); a value of <STRONG>1</STRONG>
is set if <EM>capname</EM> is not defined for this ter-
minal <EM>type</EM> (nothing is written to standard
output).
<EM>integer</EM>
a value of <STRONG>0</STRONG> is always set, whether or not
<EM>capname</EM> is defined for this terminal <EM>type</EM>. To
determine if <EM>capname</EM> is defined for this ter-
minal <EM>type</EM>, the user must test the value writ-
ten to standard output. A value of <STRONG>-1</STRONG> means
that <EM>capname</EM> is not defined for this terminal
<EM>type</EM>.
<EM>other</EM> <STRONG>reset</STRONG> or <STRONG>init</STRONG> may fail to find their respec-
tive files. In that case, the exit code is
set to 4 + <STRONG>errno</STRONG>.
Any other exit code indicates an error; see the DIAGNOS-
TICS section.
</PRE>
<H2>DIAGNOSTICS</H2><PRE>
<STRONG>tput</STRONG> prints the following error messages and sets the cor-
responding exit codes.
exit code error message

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