So your 1st file has only 1 row? if yes..

Code:
 
awk 'NR==FNR{v=$0;next}
v ~ $0{print $0"exists in 1st file"}' 1stfile 2ndfile

A small correction Smilie
Code:
awk 'NR==FNR{v=$0;next}
v !~ $0{print $0,"exists not in 1st file"}' 1stfile 2ndfile

Code:
b exists not in 1st file
c exists not in 1st file

Is there any specific reason for loop? I guess awk fits the purpose (as per your details). Are we missing anything here?
