Hi Jerome

First of all wht is see is col2 of file 1 is text & col3 of file2 is number,
so how u r going to compare?

but still you can use somewhat this way

#!/usr/bin/ksh

cut -d";" -f2 file1 >> tmpf2.txt
echo
cut -d";" -f3 file2 >> tmpf3.txt

diff tmpf2.txt tmpf3.txt

cut -d";" -f3 file1 >> tmpf3.txt
echo
cut -d";" -f4 file2 >> tmpf4.txt

diff tmpf3.txt tmpf4.txt

rm tmpf[0-9].txt
