推荐答案
尝试以下命令:
sort -k4,4 -k5,5 -k8,8 input.txt
sort手册中的
From the sort manual:
-k, --key=POS1[,POS2]
start a key at POS1, end it at POS2 (origin 1)
POS is F[.C][OPTS], where F is the field number and C the character position in the field. 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.
在您的命令中:
-k 3.42,44 表示start from (42th char of 3rd field) to (44th field).
您是说 -k 3.42,3.44 吗?
In your command:-k 3.42,44 means start from (42th char of 3rd field) to (44th field).
Do you mean -k 3.42,3.44?
