How to replace unix sort plus-notation with -k?

This is probably dead simple, but I can't get it to work. How do I correct this sort notation

sort +0 -1 something

to use more POSIX-compliant -k notation? If I try sort -k 0,1 something, sort just tells me

sort: field number is zero: invalid field specification `0,1'

I can't find it in sort 开发者_运维知识库documentation anywhere.

Try this?

sort -k1,2 something

I don't have a unix-like system on hand that allows the +0 and -1 notation, but my guess is you're looking to sort on maybe the first and second fields? The indices used in the -k flag are one-based, not zero-based, so I think you have the right idea and just need to change your 0,1 to a 1,2.

It was actually simple - I do not need the 0-th field in -k notation. So, to +0 -1, -k 1 is an equivalent.
