Have you tried using awk?
Awk can read multiple files and you can use the array concept in there.
ex: awk 'NR==FNR{A[NR]=$0;next}
{do compare operations}{save the value}' file1 file2 > file3

Is there anyway that I can compare two Arrays to see if any new strings have been added in them? eg:
Array 1: Joe Bob Jane
Array 2: Joe Bob Jane Greg
It would then output a new array with the changes:

glarrayelement
GLARRAYELEMENT(3G) GLARRAYELEMENT(3G)
NAME
glArrayElement - render a vertex using the specified vertex array element
C SPECIFICATION
void glArrayElement( GLint i )
PARAMETERS
i Specifies an index into the enabled vertex data arrays.
DESCRIPTION
glArrayElement commands are used within glBegin/glEnd pairs to specify vertex and attribute data for point, line, and polygon primitives.
If GL_VERTEX_ARRAY is enabled when glArrayElement is called, a single vertex is drawn, using vertex and attribute data taken from location
i of the enabled arrays. If GL_VERTEX_ARRAY is not enabled, no drawing occurs but the attributes corresponding to the enabled arrays are
modified.
Use glArrayElement to construct primitives by indexing vertex data, rather than by streaming through arrays of data in first-to-last order.
Because each call specifies only a single vertex, it is possible to explicitly specify per-primitive attributes such as a single normal per
individual triangle.
Changes made to array data between the execution of glBegin and the corresponding execution of glEnd may affect calls to glArrayElement
that are made within the same glBegin/glEnd period in non-sequential ways. That is, a call to
glArrayElement that precedes a change to array data may access the changed data, and a call that follows a change to array data may access
original data.
NOTES
glArrayElement is available only if the GL version is 1.1 or greater.
glArrayElement is included in display lists. If glArrayElement is entered into a display list, the necessary array data (determined by the
array pointers and enables) is also entered into the display list. Because the array pointers and enables are client-side state, their val-
ues affect display lists when the lists are created, not when the lists are executed.
