awk 小于或等于不起作用
awk less than or equal does't work
tmp.log :
[2016-12-01 00:00:01] ...
[2016-12-01 00:00:02] ....
[2016-12-01 00:00:03] .....
[2016-12-01 00:00:04] ......
命令：
awk '[=11=]>="[2016-12-01 00:00:01]" && [=11=]<="[2016-12-01 00:00:03]"' tmp.log
输出：
[2016-12-01 00:00:01] ...
[2016-12-01 00:00:02] ....
预计：
[2016-12-01 00:00:01] ...
[2016-12-01 00:00:02] ....
[2016-12-01 00:00:03] .....
为什么“<=”不起作用？
因为$0是你的整条记录，第三行是“[2016-12-01 00:00:03] .....”，比“[2016-12-01 00:00:03]".
