See setterm(1). <P>The current contents of the screen of <CODE>/dev/tty</CODE><I>N</I> can be accessed using the device <CODE>/dev/vcs</CODE><I>N</I> (where `vcs' stands for `virtual console screen'). For example, you could have a clock program that displays the current time in the upper right hand corner of the console screen (see the program <CODE>vcstime</CODE> in <CODE>kbd-1.04.tar.gz</CODE>). Just dumping the contents goes with <CODE>cat /dev/vcs</CODE><I>N</I>. These device files <CODE>/dev/vcs</CODE><I>N</I> do not contain newlines, and do not contain attributes, like colors. From a program it is usually better to use <CODE>/dev/vcsa</CODE><I>N</I> (`virtual console screen with attributes') instead - it starts with a header giving the number of rows and columns and the location of the cursor. See vcs(4). <P> <HR> <A HREF="kbd.FAQ-21.html">Next</A> <A HREF="kbd.FAQ-19.html">Previous</A> <A HREF="kbd.FAQ.html#toc20">Contents</A> </BODY> </HTML>
