Unix Compare Files
Hi,
I need to compare 2 files based on the first field in each file and output the differences to a new file.
example File 1 and File 2 both have first field as Number ie:
File 1
1252652355
1859553322
1778899562
File 2
1252652355
1859553322
So I would expect File 3 to outpt:
File 3
1778899562
I have seen loads of similiar posts like this but cant fine one specific to comparing on the first field only, as the problem I have is that the rest of the line will be different format.
Thanks
