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?
