Hi there,
I need your help, because I'm totally lost. Have no clue where to start.
I have 2 csv files (comma separated values). I have to compare the two files, at first by the first column. Anything that exists in the first file's first column, and not in the second file's first column, has to be noted. Anything that exists in the second file's first column and not in the first one's has to be noted (a command will be executed). Any idea of how to do this fast and easy?
Any help is much appreciated.
