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 output, 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 output. Before using a value returned on the standard output, the application should test the exit code (e.g., <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>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.1.html">terminfo(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 capability from the <STRONG>terminfo</STRONG> database. When <STRONG>termcap</STRONG> support is compiled in, the <STRONG>termcap</STRONG> name for the capability is also accepted. <EM>parms</EM> If the capability is a string that takes parame- ters, the arguments <EM>parms</EM> will be instantiated into the string. Most parameters are numbers. 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 capability, <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⌨️ 快捷键说明
