bash – egrep匹配组不打印？

我正在尝试创建一个bash脚本,它将使用egrep从文件中grep行.我创建了应该将我想要的信息分组的正则表达式,问题是尝试获取输出.我一直用以下命令测试它,但运行时没有打印.如何在 – {80}和断开连接之间打印多行？

egrep -E "^-{80}$\r?\n?([:ascii:]*)disconnected from Server" testing.txt

文件：testing.txt

Connected to the server: name here

Some header text.
More text to go though...
--------------------------------------------------------------------------------
The information that I want,would be in here;

Including this line as well #$
and this one.

disconnected from Server...

你可能最好使用像awk这样的工具.

awk '/^----+$/ {flag=1;next} /disconnected from Server/{flag=0} flag {print}'
