I also see your sed statements work off a-z, 0-9; - how would one account for characters that are shift + numbers as well (possibly) being in the words such as '#$%-' while unsure of their exact order therein? Can you block special characters like [!-&] much like the alpha [a-z]? Does one have to do so in correct ASCII order?
I appreciate all of your help!

NM(1) General Commands Manual NM(1)
NAME
nm - name list (symbol table)
SYNOPSIS
nm [ -aghnsu ] file ...
DESCRIPTION
Nm prints the name list of each executable or object file in the argument list. If the file is an archive (see ar(1)), the name list of
each file in the archive is printed. If more than one file is given in the argument list, the name of each file is printed at the begin-
ning of each line.
Each symbol name is preceded by its hexadecimal value (blanks if undefined) and one of the letters
T text segment symbol
t static text segment symbol
L leaf function text segment symbol
l static leaf function text segment symbol
D data segment symbol
d static data segment symbol
B bss segment symbol
b static bss segment symbol
a automatic (local) variable symbol
p function parameter symbol
z source file name
Z source file line offset
f source file name components
The output is sorted alphabetically.
Options are:
-a Print all symbols; normally only user-defined text, data, and bss segment symbols are printed.
-g Print only global (T, L, D, B) symbols.
-h Do not print file name headers with output lines.
-n Sort according to the address of the symbols.
-s Don't sort; print in symbol-table order.
-u Print only undefined symbols.
