In a BASH shell, I would like to take the lines of a file (eg pattern.txt) and find the files on my system whose names contain the patterns in each line of my file. So, I have the following for loop

for pp in `cat pattern.txt`; do find ./ -iname "*${pp}*" -print0; done

which doesn't find any files when if the first line in pattern.txt doe exist. So how can I fix the above command line?
