从男人排序：

-k,–key=KEYDEF

sort via a key; KEYDEF gives location and type

KEYDEF is F[.C][OPTS][,F[.C][OPTS]] for start and stop position,where F is a field number and C a character position in the field; both are origin 1,and the stop position defaults to the line’s end. 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 [bdfgiMhnRrV],which override global ordering options for that key. If no key is given,use the entire line as the key.
