grep does not check directories for patterns, only files. It does only descent and do recursive searches when using -R, which you don't do anyway in your example.
So you can spare out all those if/then/else/fi tests.
Also you don't have to check all files inside a for loop since grep does this on it's own when you specify a wildcard as parameter.
To see the name of the file that contains the pattern you got in your list, you can add a -l to grep.
So try something like this while standing in the directory where the supposed files are - else add some path to the wildcard accordingly:
