From the sort man page:

Code:
           -k keydef   The keydef argument defines a restricted sort key.
                       The format of this definition is

                            field_start[type][,field_end[type]]
...
                       A field_start position specified by m.n is
                       interpreted to mean the nth character in the mth
                       field.

ah i see it. it is mentioned a bit differently

POS is F[.C][OPTS], where F is the field number and C the character position in the field; both are
origin 1. If neither -t nor -b is in effect, characters in a field are counted from the beginning of
the preceding whitespace. OPTS is one or more single-letter ordering options, which override global
ordering options for that key. If no key is given, use the entire line as the key.
