Yes, I have -k in man page. but it is
-k, --key=POS1[,POS2]
start a key at POS1, end it at POS2 (origin 1)

there is no explanation for "-k.". It is comma, not dot.
thank you.

Usually further down in the page POS are explained further:

Quote:
POS is F[.C][OPTS], where F is the field number and C the character
position in the field; both are origin 1.
Check the man entries on this site they are quite good ( Linux Sort)

You may have an outdated manual page, -k is the modern way to tell sort to sort on a column. -k 1 would tell it to start at the first column (and consider all the columns thereafter), -k 1,1 would tell it to consider only the first column, etc. The options for it are quite complex.

Well, in the old days 'sort -k3,5' was 'sort +2 -4'!
