bash输出行按降序排序

Question

数据如下：

Web Application Attack: 1361698
Network Trojan was detected: 3272
Potentially Bad Traffic: 0
Misc activity: 0
Detection of Network Scan: 0

我正在寻找一个按行号排序的命令，我尝试过的任何东西都没有用。

Answer 1

试试这个：

sort -n -r -t':' -k2,2 <data_file>

说明：

-n: Numeric sort
-r: Reverse (descending)
-t: Changes field separator to ':' character
-k: Sort key starts on field 2 and ends on field 2
