Comparing with a Blacklist and saving the output

I have 2 text files, the source list, and a "black list", which it'll compare against the source list (case insensitive) and if any lines is detected with any of the blacklist lines, make a "3rd list" (output) of the offending items and line numbers (of the source file).

*cat
##dog
.pig
$qwer
|cup|
*coke*
^clock^

Give this a try:

grep -Finf blklst srclst
