-       <STRONG>clear</STRONG>  clears  your  screen if this is possible, including
-       its scrollback buffer (if the extended "E3" capability  is
-       defined).  <STRONG>clear</STRONG> looks in the environment for the terminal
-       type and then in the <STRONG>terminfo</STRONG> database to determine how to
-       clear the screen.

+       <STRONG>clear</STRONG>  clears your terminal's screen and its scrollback buffer, if any.
+       <STRONG>clear</STRONG> retrieves the terminal type from the environment  variable  <EM>TERM</EM>,
+       then  consults the <EM>terminfo</EM> terminal capability database entry for that
+       type to determine how to perform these actions.
 
-       <STRONG>clear</STRONG>  ignores  any  command-line  parameters  that may be
-       present.
+       The capabilities to clear the screen and scrollback  buffer  are  named
+       "clear"   and   "E3",  respectively.   The  latter  is  a  <EM>user-defined</EM>
+       <EM>capability</EM>, applying an extension mechanism introduced in  <EM>ncurses</EM>  5.0
+       (1999).

+       <STRONG>clear</STRONG> recognizes the following options.

+                Normally, this option is  unnecessary,  because  the  terminal
+                type  is inferred from the environment variable <EM>TERM</EM>.  If this
+                option is specified, <STRONG>clear</STRONG> ignores the  environment  variables

+

+       run <STRONG>tput</STRONG> as <STRONG>clear</STRONG>.
+
+
+</PRE><H2><a name="h2-HISTORY">HISTORY</a></H2><PRE>
+       A <STRONG>clear</STRONG> command using the <EM>termcap</EM> database and library appeared in 2BSD
+       (1979).  Eighth Edition Unix (1985) later included it.
+
+       The commercial Unix arm of AT&amp;T adapted a different BSD program  (<STRONG>tset</STRONG>)
+       to  make  a  new  command,  <STRONG>tput</STRONG>, and replaced the <STRONG>clear</STRONG> program with a
+       shell script that called "<STRONG>tput</STRONG> <STRONG>clear</STRONG>".
+
+           /usr/bin/tput ${1:+-T$1} clear 2&gt; /dev/null
+           exit
+
+       In 1989, when Keith Bostic revised the BSD  <STRONG>tput</STRONG>  command  to  make  it
+       similar to AT&amp;T's <STRONG>tput</STRONG>, he added a <STRONG>clear</STRONG> shell script as well.
+
+           exec tput clear
+
+       The remainder of the script in each case is a copyright notice.
+
+       In 1995, <EM>ncurses</EM>'s <STRONG>clear</STRONG> began by adapting BSD's original <STRONG>clear</STRONG> command
+       to use <EM>terminfo</EM>.  The <STRONG>E3</STRONG> extension came later.
+
+       <STRONG>o</STRONG>   In June 1999, <EM>xterm</EM> provided an extension to the  standard  control
+           sequence  for  clearing  the screen.  Rather than clearing just the
+           visible part of the screen using
+
+               printf '\033[2J'
+
+           one could clear the scrollback buffer as well by using
+
+               printf '\033[<STRONG>3</STRONG>J'
+
+           instead.  "XTerm  Control  Sequences"  documents  this  feature  as
+           originating with <EM>xterm</EM>.
+
+       <STRONG>o</STRONG>   A few other terminal emulators adopted it, such as PuTTY in 2006.
+
+       <STRONG>o</STRONG>   In  April  2011, a Red Hat developer submitted a patch to the Linux
+           kernel,  modifying  its  console  driver  to  do  the  same  thing.
+           Documentation  of  this  change,  appearing  in  Linux 3.0, did not
+           mention <EM>xterm</EM>, although that program was cited in the Red  Hat  bug
+           report (#683733) motivating the feature.
+
+       <STRONG>o</STRONG>   Subsequently,  more  terminal  developers adopted the feature.  The
+           next relevant step was to change the <EM>ncurses</EM> <STRONG>clear</STRONG> program in  2013
+           to incorporate this extension.
+
+       <STRONG>o</STRONG>   In 2013, the <STRONG>E3</STRONG> capability was not exercised by "<STRONG>tput</STRONG> <STRONG>clear</STRONG>".  That
+           oversight was addressed in 2016 by reorganizing <STRONG>tput</STRONG> to  share  its
+           logic with <STRONG>clear</STRONG> and <STRONG>tset</STRONG>.
