Diff and intersection reporting between two text files
sort | uniq is good, but comm might be even better. "man comm" for more information.
From the manual page:
EXAMPLES comm -12 file1 file2 Print only lines present in both file1 and file2. comm -3 file1 file2 Print lines in file1 not in file2, and vice versa.You can also use the Python set type, but comm is easier.
words1 = set(open("some1.txt").read().split())words2 = set(open("some2.txt").read().split())duplicates = words1.intersection(words2)uniques = words1.difference(words2).union(words2.difference(words1))print "Duplicates(%d):%s"%(len(duplicates),duplicates)print "\nUniques(%d):%s"%(len(uniques),uniques)something like that at least
