[Perl] Accessing array elements within a sed command in Perl script
I am trying to use a script to replace the header of each file, whose filename are stored within the array $test, using the sed command within a Perl script as follows:
Code:
$count = 0;
while ( $count < $#test )
{
        `sed -e 's/BIOGRF  321/BIOGRF  332/g' ${test[$count]} > 0`;
        `cat 0 > ${test[$count]}`;
        $count++;
}

`rm 0`;

This script doesn't work as is and I think it might be something with the syntax of how to call the element of an array within a embedded sed command. If I put an actual integer as the array index instead of the variable $count, it works fine, but if I try to use $count, it doesn't work at all. I know this might not be the most efficient method, but it is the only way I can think of with my limited knowledge of perl scripting.

glscissorarray

GLSCISSORARRAY(3G)						  [FIXME: manual]						GLSCISSORARRAY(3G)

NAME

       glScissorArray - define the scissor box for multiple viewports

C SPECIFICATION

       void glScissorArrayv(GLuint first, GLsizei count, const GLint *v);

PARAMETERS

       first
	   Specifies the index of the first viewport whose scissor box to modify.

       count
	   Specifies the number of scissor boxes to modify.

       v
	   Specifies the address of an array containing the left, bottom, width and height of each scissor box, in that order.

DESCRIPTION

       glScissorArrayv defines rectangles, called scissor boxes, in window coordinates for each viewport.  first specifies the index of the first
       scissor box to modify and count specifies the number of scissor boxes to modify.  first must be less than the value of GL_MAX_VIEWPORTS,
       and first + count must be less than or equal to the value of GL_MAX_VIEWPORTS.  v specifies the address of an array containing integers
       specifying the lower left corner of the scissor boxes, and the width and height of the scissor boxes, in that order.

       To enable and disable the scissor test, call glEnable() and glDisable() with argument GL_SCISSOR_TEST. The test is initially disabled for
       all viewports. While the test is enabled, only pixels that lie within the scissor box can be modified by drawing commands. Window
       coordinates have integer values at the shared corners of frame buffer pixels.  glScissor(0,0,1,1) allows modification of only the lower
       left pixel in the window, and glScissor(0,0,0,0) doesn't allow modification of any pixels in the window.

       When the scissor test is disabled, it is as though the scissor box includes the entire window.

ERRORS

       GL_INVALID_VALUE is generated if first is greater than or equal to the value of GL_MAX_VIEWPORTS.

       GL_INVALID_VALUE is generated if first + count is greater than or equal to the value of GL_MAX_VIEWPORTS.

       GL_INVALID_VALUE is generated if any width or height specified in the array v is negative.

ASSOCIATED GETS

       glGet() with argument GL_SCISSOR_BOX

       glIsEnabled() with argument GL_SCISSOR_TEST
