  • is order important in matching? for ex: world should always be after hello or can it occur before also? Commented Mar 13, 2017 at 15:11
  • also, hello and tshirt (i.e word from file1 line1 and word from file2 line2) should also be matched? or is it only same line numbers from both files Commented Mar 13, 2017 at 15:14
  • file1 should be first then file2. My main problem is the loop itself because I have to read 2 files. for example I was able to create a loop with a single file where it greps through the list and trying to find matching words in the destination folder. Thanks Commented Mar 13, 2017 at 15:17
  • line 1 in file1 and line 1 in file2 should match. Commented Mar 13, 2017 at 15:18

    ok, try this single command instead of script, grep -f <(pr -mts'.*' file1.txt file2.txt) /root/listoffiles/*php >> found.txt Commented Mar 13, 2017 at 15:20
