差集：

sort a.txt b.txt b.txt | uniq -u

fffff

说明： sort 先给文件排序。
-d 显示次数大于一次的行
-u 显示次数仅为一次的行

方法2: comm

第二列：a没有，b有。 b差a comm -1 -3 a.txt b.txt
第三列：ab都有 a交b comm -1 -2 a.txt b.txt

大小写互转

注意： 以下命令Mac OS无效

sed ‘s/[a-z]/\u&/g’
sed ‘s/[A-Z]/\l&/g’

拆解每一行中固定关键字的列

sed ‘s/.(action=[a-zA-Z]{1,}).(cmd=[_a-zA-Z-]{1,})./\1 \2/‘
注意：在次数匹配时：
1）圆括号必须转义
2）花括号必须转义
