请大家帮忙，先谢了！
我想实现这样的功能：  在文本中有很多段如，以Starting行开头， exit行开头结尾的段，Starting 到exit中间的数据不一样，还有其他不一样开头的数据。

比如文本内容：

Starting (AXX BXX CXXX DXX EXX FXX HXX GXX IXX)
2017/03/02 17:37:16 ** Error: Unable to determine server for project 'test'.
2017/03/02 17:37:16 ** Error: Unable to determine server for project 'test'.
2017/03/02 17:37:16 ** Error: Unable to determine server for project 'test'.
2017/03/02 17:37:16 ** Error: Unable to determine server for project 'test'.

2017/03/02 17:37:16 ** Error: Unable to determine server for project 'test'.
2017/03/02 17:37:16 ** Error: Unable to determine server for project 'test'.
2017/03/02 17:37:16 ** Error: Unable to determine server for project 'test'.
2017/03/02 17:37:16 ** Error: Unable to determine server for project 'test'.

exit status=0

License Option: ident

Starting (AXX BXX CXXX DXX EXX FXX HXX GXX IXX)
2017/03/02 17:37:16 ** Error: Unable to determine server for project 'test'.
2017/03/02 17:37:16 ** Error: Unable to determine server for project 'test'.


exit status=0

The message returned from the system is: libgd_sh.so: cannot open shared object file: No such file or directory


Starting (AXX BXX CXXX DXX EXX FXX HXX GXX IXX)
2017/03/02 17:37:16 ** Error: Unable to determine server for project 'test'.

2017/03/02 17:37:16 ** Error: Unable to determine server for project 'test'.


exit status=0

怎么用正则表示式实现： 把Starting 到 exit所有段的内容抓出来？

1. awk '/^Starting/{f=1}f;/^exit/{f=0}' urfile

多谢！达到目的了，能否解释下f=1 f=0是什么功能？
非常感谢！

1. s/(?<=exit\sstatus=0\n)((?!Starting).*\n)*//g

一个用于标识的变量 在区间开始(Starting)的时候开启 在区间结束(exit)的时候关闭

moperyblue

1. grep -oPz '^(Starting.*\n)(.*\n)*?exit.*' urfile
