- -k, --key=POS1[,POS2]
- start a key at POS1 (origin 1), end it at POS2 (default end of line). See POS syntax below
復(fù)制代碼- 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.
-
復(fù)制代碼 所以這里的-k6,6應(yīng)該是指第六列的意思
至于第二個(gè)問題,我覺得放在-k的后面意味僅僅對(duì)這一列有作用。
