Hi, I need a unix script which can check the values from file1 into file2 and if they do not match then print that line from file1. file1 check1 name1 lastname1 email check2 name1 lastname1 email check30 name1 lastname1 email check3 name1 lastname1 email File2 check1 name1 lastname1 email check1 name1 lastname1 email check2 name1 lastname1 email check3 name1 lastname1 email check5 name1 lastname1 email Output: check30 name1 lastname1 email Thanks

This script matches on word1 only, but could just as easily match on entire line. awk 'BEGIN{ while ((getline < "file2") > 0) list[$1] = 1} !list[$1] {print}' file1

good morning all i have a problem which is: I have two file file1 12 CD 1234 54 RC 6543 45 CD 4567 65 RC 2345 file2 45 CD 4567 54 RC 6543 I want to take every line in file1 and search in file2 if the line does not exsist print it in a new file the output should be like this file3 12 CD 1234 65 RC 2345 please Help!

I want the solution with nawk if possible
