      I added set -xv

argument makes # the read utility process a "line" until the first such 
delimiter # is found. Since an empty string in C is terminated by a NULL # 
character, the delimiter will be set to this NULL character. # Hence, assuming 
that the input string does not contain any # NULL characters, the whole input 
string will be treated as # one big line. # Then, normal word splitting kicks 
in and the -a flag tells # read to put all words into elements of the provided
