Check this [ "$(echo -e "Mc Kevin\nsteffen" | sort -u | wc -l)" -eq 2 ] && echo The question owner is not steffen

thanks, I tried -s, but i missed out the 1,1 instead and did -k 1, what is the number after the , doing?

-kn,m: Sort by fields n-m (e. g. fields 1-4) where m defaults to end of line. If you sort from 1-1, only the first field is taken for comparison.
