I am quite new to bash scripting and so any help would be much appreciated. Below is what I want to achieve.
I have two text files. I want to delete all of the lines on the first file where it matches any of my string on the second file before the a comma.
this_is_a_test.txt,11dsdsdsdsd this_is_a_test24.txt,545467ddd this_is_a_test22,121244442
this_is_a_test.txt this_is_a_test24.txt this_is_a_test22
Desired Output: Blank
