I have two files A1 and A2 (unsorted). A1 is previous version of A2 and some lines have been added to A2. How can I get the new lines that are added to A2?
Note: I just want the new lines added and dont want the lines which were in A1 but deleted in A2. When i do
diff A1 A2
diff and then
grep for the edit type you want.
diff -u A1 A2 | grep -E "^\+"
