+ fix several formatting issues with manual pages. + correct read of terminfo entry in which all strings are absent or explicitly cancelled. Before this fix, the result was that all were treated as only absent. + modify infocmp to suppress mixture of absent/cancelled capabilities that would only show as "NULL, NULL", unless the -q option is used, e.g., to show "-, @" or "@, -".

|
|
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>sh(1)</STRONG>), to initialize or reset
|
|
the terminal, or return the long name of the requested
|
|
terminal type. The result depends upon the capability's
|
|
type:
|
|
|
|
string
|
|
<STRONG>tput</STRONG> writes the string to the standard output. No
|
|
trailing newline is supplied.
|
|
|
|
integer
|
|
<STRONG>tput</STRONG> writes the decimal value to the standard out-
|
|
put, with a trailing newline.
|
|
|
|
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 writes nothing to the standard out-
|
|
put.
|
|
|
|
Before using a value returned on the standard output, the
|
|
application should test the exit code (e.g., <STRONG>$?</STRONG>, see
|
|
<STRONG>sh(1)</STRONG>) to be sure it is <STRONG>0</STRONG>. (See the <STRONG>EXIT</STRONG> <STRONG>CODES</STRONG> and <STRONG>DIAG-</STRONG>
|
|
<STRONG>NOSTICS</STRONG> sections.) For a complete list of capabilities
|
|
and the <EM>capname</EM> associated with each, see <STRONG><A HREF="terminfo.5.html">terminfo(5)</A></STRONG>.
|
|
|
|
|
|
</PRE><H3><a name="h3-Options">Options</a></H3><PRE>
|
|
<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 also be ignored.
|
|
|
|
<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><A HREF="curs_terminfo.3x.html">tparm(3x)</A></STRONG>, and how to interpret the parameters.
|
|
|
|
<STRONG>-V</STRONG> reports the version of ncurses which was used in
|
|
this program, and exits.
|
|
|
|
|
|
</PRE><H3><a name="h3-Commands">Commands</a></H3><PRE>
|
|
A few commands (<STRONG>init</STRONG>, <STRONG>reset</STRONG> and <STRONG>longname</STRONG>) are special;
|
|
they are defined by the <STRONG>tput</STRONG> program. The others are the
|
|
names of <EM>capabilities</EM> from the terminal database (see <STRONG>ter-</STRONG>
|
|
<STRONG><A HREF="terminfo.5.html">minfo(5)</A></STRONG> for a list). Although <STRONG>init</STRONG> and <STRONG>reset</STRONG> resemble
|
|
capability names, <STRONG>tput</STRONG> uses several capabilities to per-
|
|
form these special functions.
|
|
|
|
<EM>capname</EM>
|
|
indicates the capability from the terminal data-
|
|
base.
|
|
|
|
If the capability is a string that takes parame-
|
|
ters, the arguments following the capability will
|
|
be used as parameters for the string.
|
|
|
|
Most parameters are numbers. Only a few terminal
|
|
capabilities require string parameters; <STRONG>tput</STRONG> uses a
|
|
table to decide which to pass as strings. Normally
|
|
<STRONG>tput</STRONG> uses <STRONG><A HREF="curs_terminfo.3x.html">tparm(3x)</A></STRONG> to perform the substitution.
|
|
If no parameters are given for the capability, <STRONG>tput</STRONG>
|
|
writes the string without performing the substitu-
|
|
tion.
|
|
|
|
<STRONG>init</STRONG> If the terminal 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) first, <STRONG>tput</STRONG> retrieves the current terminal
|
|
mode settings for your terminal. It does this
|
|
by successively testing
|
|
|
|
<STRONG>o</STRONG> the standard error,
|
|
|
|
<STRONG>o</STRONG> standard output,
|
|
|
|
<STRONG>o</STRONG> standard input and
|
|
|
|
<STRONG>o</STRONG> ultimately "/dev/tty"
|
|
|
|
to obtain terminal settings. Having retrieved
|
|
these settings, <STRONG>tput</STRONG> remembers which file
|
|
descriptor to use when updating settings.
|
|
|
|
(2) if the window size cannot be obtained from the
|
|
operating system, but the terminal description
|
|
(or environment, e.g., <STRONG>LINES</STRONG> and <STRONG>COLUMNS</STRONG> vari-
|
|
ables specify this), update the operating sys-
|
|
tem's notion of the window size.
|
|
|
|
(3) the terminal modes will be updated:
|
|
|
|
<STRONG>o</STRONG> any delays (e.g., newline) specified in
|
|
the entry will be set in the tty driver,
|
|
|
|
<STRONG>o</STRONG> tabs expansion will be turned on or off
|
|
according to the specification in the
|
|
entry, and
|
|
|
|
<STRONG>o</STRONG> if tabs are not expanded, standard tabs
|
|
will be set (every 8 spaces).
|
|
|
|
(4) if present, the terminal's initialization
|
|
strings will be output as detailed in the <STRONG>ter-</STRONG>
|
|
<STRONG><A HREF="terminfo.5.html">minfo(5)</A></STRONG> section on <EM>Tabs</EM> <EM>and</EM> <EM>Initialization</EM>,
|
|
|
|
(5) output is flushed.
|
|
|
|
If an entry does not contain the information needed
|
|
for any of these activities, that activity will
|
|
silently be skipped.
|
|
|
|
<STRONG>reset</STRONG> This is similar to <STRONG>init</STRONG>, with two differences:
|
|
|
|
(1) before any other initialization, the terminal
|
|
modes will be reset to a "sane" state:
|
|
|
|
<STRONG>o</STRONG> set cooked and echo modes,
|
|
|
|
<STRONG>o</STRONG> turn off cbreak and raw modes,
|
|
|
|
<STRONG>o</STRONG> turn on newline translation and
|
|
|
|
<STRONG>o</STRONG> reset any unset special characters to
|
|
their default values
|
|
|
|
(2) Instead of putting out <EM>initialization</EM> strings,
|
|
the terminal's <EM>reset</EM> strings will be output if
|
|
present (<STRONG>rs1</STRONG>, <STRONG>rs2</STRONG>, <STRONG>rs3</STRONG>, <STRONG>rf</STRONG>). If the <EM>reset</EM>
|
|
strings are not present, but <EM>initialization</EM>
|
|
strings are, the <EM>initialization</EM> strings will
|
|
be output.
|
|
|
|
Otherwise, <STRONG>reset</STRONG> acts identically to <STRONG>init</STRONG>.
|
|
|
|
<STRONG>longname</STRONG>
|
|
If the terminal 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>].
|

|
|
<STRONG>tput</STRONG> handles the <STRONG>clear</STRONG>, <STRONG>init</STRONG> and <STRONG>reset</STRONG> commands specially:
|
|
it allows for the possibility that it is invoked by a link
|
|
with those names.
|
|
|
|
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>. The <STRONG><A HREF="tset.1.html">tset(1)</A></STRONG> utility also
|
|
treats a link named <STRONG>reset</STRONG> specially.
|
|
|
|
Before ncurses 6.1, the two utilities were different from
|
|
each other:
|
|
|
|
<STRONG>o</STRONG> <STRONG>tset</STRONG> utility reset the terminal modes and special
|
|
characters (not done with <STRONG>tput</STRONG>).
|
|
|
|
<STRONG>o</STRONG> On the other hand, <STRONG>tset</STRONG>'s repertoire of terminal capa-
|
|
bilities for resetting the terminal was more limited,
|
|
i.e., only <STRONG>reset_1string</STRONG>, <STRONG>reset_2string</STRONG> and <STRONG>reset_file</STRONG>
|
|
in contrast to the tab-stops and margins which are set
|
|
by this utility.
|
|
|
|
<STRONG>o</STRONG> The <STRONG>reset</STRONG> program is usually an alias for <STRONG>tset</STRONG>,
|
|
because of this difference with resetting terminal
|
|
modes and special characters.
|
|
|
|
With the changes made for ncurses 6.1, the <EM>reset</EM> feature
|
|
of the two programs is (mostly) the same. A few differ-
|
|
ences remain:
|
|
|
|
<STRONG>o</STRONG> The <STRONG>tset</STRONG> program waits one second when resetting, in
|
|
case it happens to be a hardware terminal.
|
|
|
|
<STRONG>o</STRONG> The two programs write the terminal initialization
|
|
strings to different streams (i.e.,. the standard
|
|
error for <STRONG>tset</STRONG> and the standard output for <STRONG>tput</STRONG>).
|
|
|
|
<STRONG>Note:</STRONG> although these programs write to different
|
|
streams, redirecting their output to a file will cap-
|
|
ture only part of their actions. The changes to the
|
|
terminal modes are not affected by redirecting the
|
|
output.
|
|
|
|
If <STRONG>tput</STRONG> is invoked by a link named <STRONG>init</STRONG>, this has the same
|
|
effect as <STRONG>tput</STRONG> <STRONG>init</STRONG>. Again, you are less likely to use
|
|
that link because another program named <STRONG>init</STRONG> has a more
|
|
well-established use.

<STRONG>tput</STRONG> <STRONG>init</STRONG>
|
|
Initialize the terminal according to the type of ter-

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

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

The <STRONG>tput</STRONG> command was begun by Bill Joy in 1980. The ini-
|
|
tial version only cleared the screen.
|
|
|
|
AT&T System V provided a different <STRONG>tput</STRONG> command, whose
|
|
<STRONG>init</STRONG> and <STRONG>reset</STRONG> subcommands (more than half the program)
|
|
were incorporated from the <STRONG>reset</STRONG> feature of BSD <STRONG>tset</STRONG> writ-
|
|
ten by Eric Allman.
|
|
|
|
Keith Bostic replaced the BSD <STRONG>tput</STRONG> command in 1989 with a
|
|
new implementation based on the AT&T System V program
|
|
<STRONG>tput</STRONG>. Like the AT&T program, Bostic's version accepted
|
|
some parameters named for <EM>terminfo</EM> <EM>capabilities</EM> (<STRONG>clear</STRONG>,
|
|
<STRONG>init</STRONG>, <STRONG>longname</STRONG> and <STRONG>reset</STRONG>). However (because he had only
|
|
termcap available), it accepted <EM>termcap</EM> <EM>names</EM> for other
|
|
capabilities. Also, Bostic's BSD <STRONG>tput</STRONG> did not modify the
|
|
terminal I/O modes as the earlier BSD <STRONG>tset</STRONG> had done.
|
|
|
|
At the same time, Bostic added a shell script named
|
|
"clear", which used <STRONG>tput</STRONG> to clear the screen.
|
|
|
|
Both of these appeared in 4.4BSD, becoming the "modern"
|
|
BSD implementation of <STRONG>tput</STRONG>.
|
|
|
|
This implementation of <STRONG>tput</STRONG> began from a different source
|
|
than AT&T or BSD: Ross Ridge's <EM>mytinfo</EM> package, published
|
|
on <EM>comp.sources.unix</EM> in December 1992. Ridge's program
|
|
made more sophisticated use of the terminal capabilities
|
|
than the BSD program. Eric Raymond used the <STRONG>tput</STRONG> program
|
|
(and other parts of <EM>mytinfo</EM>) in ncurses in June 1995.
|
|
Using the portions dealing with terminal capabilities
|
|
almost without change, Raymond made improvements to the
|
|
way the command-line parameters were handled.

|
|
This implementation of <STRONG>tput</STRONG> differs from AT&T <STRONG>tput</STRONG> in two
|
|
important areas:
|
|
|
|
<STRONG>o</STRONG> <STRONG>tput</STRONG> <EM>capname</EM> writes to the standard output. That need
|
|
not be a regular terminal. However, the subcommands
|
|
which manipulate terminal modes may not use the stan-
|
|
dard output.
|
|
|
|
The AT&T implementation's <STRONG>init</STRONG> and <STRONG>reset</STRONG> commands use
|
|
the BSD (4.1c) <STRONG>tset</STRONG> source, which manipulates terminal
|
|
modes. It successively tries standard output, stan-
|
|
dard error, standard input before falling back to
|
|
"/dev/tty" and finally just assumes a 1200Bd terminal.
|
|
When updating terminal modes, it ignores errors.
|
|
|
|
Until changes made after ncurses 6.0, <STRONG>tput</STRONG> did not
|
|
modify terminal modes. <STRONG>tput</STRONG> now uses a similar
|
|
scheme, using functions shared with <STRONG>tset</STRONG> (and ulti-
|
|
mately based on the 4.4BSD <STRONG>tset</STRONG>). If it is not able
|
|
to open a terminal, e.g., when running in <STRONG>cron</STRONG>, <STRONG>tput</STRONG>
|
|
will return an error.
|
|
|
|
<STRONG>o</STRONG> AT&T <STRONG>tput</STRONG> guesses the type of its <EM>capname</EM> operands by
|
|
seeing if all of the characters are numeric, or not.
|
|
|
|
Most implementations which provide support for <EM>capname</EM>
|
|
operands use the <EM>tparm</EM> function to expand parameters
|
|
in it. That function expects a mixture of numeric and
|
|
string parameters, requiring <STRONG>tput</STRONG> to know which type
|
|
to use.
|
|
|
|
This implementation uses a table to determine the
|
|
parameter types for the standard <EM>capname</EM> operands, and
|
|
an internal library function to analyze nonstandard
|
|
<EM>capname</EM> operands.
|
|
|
|
This implementation (unlike others) can accept both <EM>term-</EM>
|
|
<EM>cap</EM> and <EM>terminfo</EM> names for the <EM>capname</EM> feature, if <EM>termcap</EM>
|
|
support is compiled in. However, the predefined <EM>termcap</EM>
|
|
and <EM>terminfo</EM> names have two ambiguities in this case (and
|
|
the <EM>terminfo</EM> name is assumed):
|
|
|
|
<STRONG>o</STRONG> The <EM>termcap</EM> name <STRONG>dl</STRONG> corresponds to the <EM>terminfo</EM> name
|
|
<STRONG>dl1</STRONG> (delete one line).
|
|
The <EM>terminfo</EM> name <STRONG>dl</STRONG> corresponds to the <EM>termcap</EM> name
|
|
<STRONG>DL</STRONG> (delete a given number of lines).
|
|
|
|
<STRONG>o</STRONG> The <EM>termcap</EM> name <STRONG>ed</STRONG> corresponds to the <EM>terminfo</EM> name
|
|
<STRONG>rmdc</STRONG> (end delete mode).
|
|
The <EM>terminfo</EM> name <STRONG>ed</STRONG> corresponds to the <EM>termcap</EM> name
|
|
<STRONG>cd</STRONG> (clear to end of screen).
|
|
|
|
The <STRONG>longname</STRONG> and <STRONG>-S</STRONG> options, and the parameter-substitu-
|
|
tion features used in the <STRONG>cup</STRONG> example, were not supported
|
|
in BSD curses before 4.3reno (1989) or in AT&T/USL curses
|
|
before SVr4 (1988).
|
|
|
|
IEEE Std 1003.1/The Open Group Base Specifications Issue
|
|
7 (POSIX.1-2008) documents only the operands for <STRONG>clear</STRONG>,
|
|
<STRONG>init</STRONG> and <STRONG>reset</STRONG>. There are a few interesting observations
|
|
to make regarding that:
|
|
|
|
<STRONG>o</STRONG> In this implementation, <STRONG>clear</STRONG> is part of the <EM>capname</EM>
|
|
support. The others (<STRONG>init</STRONG> and <STRONG>longname</STRONG>) do not corre-
|
|
spond to terminal capabilities.
|
|
|
|
<STRONG>o</STRONG> Other implementations of <STRONG>tput</STRONG> on SVr4-based systems
|
|
such as Solaris, IRIX64 and HPUX as well as others
|
|
such as AIX and Tru64 provide support for <EM>capname</EM> op-
|
|
erands.
|
|
|
|
<STRONG>o</STRONG> A few platforms such as FreeBSD recognize termcap
|
|
names rather than terminfo capability names in their
|
|
respective <STRONG>tput</STRONG> commands. Since 2010, NetBSD's <STRONG>tput</STRONG>
|
|
uses terminfo names. Before that, it (like FreeBSD)
|
|
recognized termcap names.
|
|
|
|
Because (apparently) <EM>all</EM> of the certified Unix systems
|
|
support the full set of capability names, the reasoning
|
|
for documenting only a few may not be apparent.
|
|
|
|
<STRONG>o</STRONG> X/Open Curses Issue 7 documents <STRONG>tput</STRONG> differently, with
|
|
<EM>capname</EM> and the other features used in this implemen-
|
|
tation.
|
|
|
|
<STRONG>o</STRONG> That is, there are two standards for <STRONG>tput</STRONG>: POSIX (a
|
|
subset) and X/Open Curses (the full implementation).
|
|
POSIX documents a subset to avoid the complication of
|
|
including X/Open Curses and the terminal capabilities
|
|
database.
|
|
|
|
<STRONG>o</STRONG> While it is certainly possible to write a <STRONG>tput</STRONG> program
|
|
without using curses, none of the systems which have a
|
|
curses implementation provide a <STRONG>tput</STRONG> utility which
|
|
does not provide the <EM>capname</EM> feature.
