测试日志：

--- The error occurred in com//tmo/asfjn/jdaf/tkenjrt/terkj.xml
--- The error occurred while eating sandwich.
--- Check the tim-tim-nothing-boy.
--- Cause: java.sql.SQLException: ORA-00001: You suck.
ORA-06512: at "test_amp_tim.pkg", line 78

现在我希望脚本查找“UserDefined Tatty Error”并从“发生错误......”一直打印到“你太糟糕了”。

我尝试了 grep -Fxq 和 sed，但没有成功。谢谢。

答案1

像这样的东西吗？

awk '# If we see the error, set t to 1
    /UserDefined Tatty Error/ { t=1; next }
    # If it's not a --- reset t to 0 (even if it's already 0)
    !/^--- / { t=0 }
    # If t==1 we are inside the error message; so, print
    t' file

答案2

awk '/UserDefined Tatty Error/,/You suck/' file
