Read 2 files and compare them for duplicates

(0) ShareShare

Posted on by

I have two .csv files (fileYesterday) and (fileToday) and would like to compare them and produce an additional .csv that contains only the differences in the two files.  The unique ID is 'uid' and the other columns contain role and login (date/timeZ).  How can I read both .csv files and put them in another file with only the differences listed?  Or at least add a column in 'fileToday' showing if the row is different from 'fileYesterday'?
