我想用一个正则表达式查找文件中的所有错误，但不是包含＆＃34; Internet Explorer 11＆＃34;的错误行。
使用regex101.com我能够找出这个正则表达式我能够找到一个与此匹配的正则表达式：(\[.*error.*\])(?!.*Internet Explorer 11.*)
现在我想知道如何在命令行上执行此操作来测试它。
我尝试了什么
这些显示没有输出（必须转义!
grep "(\[.*error.*\]){1,}(?\!.*Internet Explorer 11.*)" /var/log/upstart/app.log
egrep "(\[.*error.*\]){1,}(?\!.*Internet Explorer 11.*)" /var/log/upstart/app.log
任何人都知道如何做到这一点？任何帮助表示赞赏

像(?!...)这样的先行模式特定于Perl正则表达式，而不是grep使用的常用基本和扩展正则表达式的一部分。
但是你想要的是用grep和管道很容易做到的事情：
grep -F '[error]' /var/log/upstart/app.log | grep -vF 'Internet Explorer 11'
或者您可以使用grep -P（使用GNU grep）或pcregrep，它们支持Perl正则表达式：
pcregrep '(\[.*error.*\])(?!.*Internet Explorer 11.*)' /var/log/upstart/app.log
（GNU grep的手册提到-P是＆＃34;高度实验性的＃34;但它并不是一个新功能，并且在实践中似乎工作精细。）

使用单个 awk 命令：
awk '$4~/error/ && $0!~/Internet Explorer 11/' file
输出：

有更简单的管道方法，不包括使用grep（-v）开关......但如果你确实需要纯正则表达式解决方案：
grep -P '^((?!Internet\ Explorer\ 11).)*\[error\]((?!Internet\ Explorer\ 11).)*$' filename
这里-P使用perl正则表达式，我认为这是前瞻性所必需的
