While correct, you do realize that cp overwrites the errorFile with tempFile -- it does not append. May I suggest:
Code:
#!/usr/bin/bash
ERRFILE="errorFile"

nawk -v ERR=$ERRFILE '{
  ... scan each field for errors
  print $1, "Error message ..." >> ERR
  print $2, "Error message ..." >> ERR
  ...
}' xx.txt

This will append the errors to errorFile, which is only created if an error is found.
