help with diff compare
I'm new to the use of diff.
I am trying to compare the contents of two text lists and get an output of the DIFFERENCES in the two files as a txt file. I thought I had it figured out, but I have yet to get the correct results.
Am I using the correct command, and if I am, what options need to be appended to this command to get the result of (contents of lines in list A)-(contents of lines of list b), where b is a subset of a (list b contains records of list a).
I am trying to find the items not represented in the second list.
An answer would be sufficient, but a "why" accompanying the answer would be much appreciated. Teach a man to fish.
Thankful for any help.
