The " inside the javascript will be eaten by the shell because they're not escaped. It doesn't know the quotes are supposed to be for javascript, and handles them itself.

Code:

$ echo " window.status = "Redirecting..." + myvar;"
 window.status = Redirecting... + myvar;

$ echo " window.status = \"Redirecting...\" + myvar;"
 window.status = "Redirecting..." + myvar;

$

...but it'll be more efficient and far less typo-prone to do this in a here-document, that will let you plunk it down nearly verbatim:

Code:

cat <<EOF
<script type="text/javascript">"
function exec_refresh()
{
window.status = "Redirecting..." + myvar;
myvar = myvar + " .";"
var timerID = setTimeout("exec_refresh();", 100);
if (timeout > 0)
{
timeout -= 1;
}
else
{
clearTimeout(timerID);
window.status = "";
window.location = "Test.com Web Based Testing and Certification Software v2.0";
}
}
var myvar = "";
var timeout = 20;
exec_refresh();
</script>
EOF

${VARIABLES} and `backticks` will still be substituted inside a here document. Escape ` and $ with \ to avoid it.

Note the ending EOF must be at the beginning of the line, not indented!

glutvisibilityfunc

glutVisibilityFunc(3GLUT)					       GLUT						 glutVisibilityFunc(3GLUT)

NAME

       glutVisibilityFunc - sets the visibility callback for the current window.

SYNTAX

       void glutVisibilityFunc(void (*func)(int state));

ARGUMENTS

       func	 The new visibility callback function.

DESCRIPTION

       glutVisibilityFunc  sets the visibility callback for the current window. The visibility callback for a window is called when the visibility
       of a window changes. The state callback parameter is either GLUT_NOT_VISIBLE or GLUT_VISIBLE depending on the  current  visibility  of  the
       window.	GLUT_VISIBLE does not distinguish a window being totally versus partially visible. GLUT_NOT_VISIBLE means no part of the window is
       visible, i.e., until the window's visibility changes, all further rendering to the window is discarded.

       GLUT considers a window visible if any pixel of the window is visible or any pixel of any descendant window is visible on the screen.

       Passing NULL to glutVisibilityFunc disables the generation of the visibility callback.

       If the visibility callback for a window is disabled and later re-enabled, the visibility status of the window is undefined; any	change	in
       window  visibility  will  be reported, that is if you disable a visibility callback and re-enable the callback, you are guaranteed the next
       visibility change will be reported.
