+ A few commands (<STRONG>init</STRONG>, <STRONG>reset</STRONG> and <STRONG>longname</STRONG>) are special;

+ capability names, <STRONG>tput</STRONG> uses several capabilities to per-
+ form these special functions.
+
<EM>capname</EM>

- base. When <STRONG>termcap</STRONG> support is compiled in, the
- <STRONG>termcap</STRONG> name for the capability is also accepted.

+ 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 <STRONG>terminfo</STRONG> database is present and an entry
+ <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) 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>,
+ (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"
- (2) any delays (e.g., newline) specified in the
- entry will be set in the tty driver,
+ to obtain terminal settings. Having retrieved
+ these settings, <STRONG>tput</STRONG> remembers which file
+ descriptor to use when updating settings.
- (3) tabs expansion will be turned on or off
- according to the specification in the entry,
- and
+ (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>,
- (4) if tabs are not expanded, standard tabs will
- be set (every 8 spaces).
+ (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> 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>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 <STRONG>terminfo</STRONG> database is present and an entry
+ 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
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
+ effect as <STRONG>tput</STRONG> <STRONG>init</STRONG>. Again, you are less likely to use

well-established use.
