Hrm, on second look, my example was inappropriate. In order to demonstrate no sorting, I should have said something like:
input.txt: f e d c b a e patternfile.txt: a c e $ cat input.txt | grep -f patternfile.txt e c a e grep will scan the input file line by line. If the current line matches any of the patterns in the pattern file, it prints it. Maybe that makes more sense. Chris Santerre said: > Your example is EXACTLY what was happening to me!
