grep -v模式文件将为您提供文件中的行 t包含模式

给定文本文件或输入流有不同的排除和grep方法。我通常更喜欢使用两个grep的最基本的一个，其中第一个用于使用-v选项排除，而管道用于第二个用于grep我的字符串。 grep -v'能'config.txt | grep'ystem'有关详细信息，请参阅 https://www.poftut.com/introduction -to-Linux的grep的命令与 - 实例/

man grep would tell you.

grep -v pattern file will give you the lines in file that don't contain pattern

There are different ways to exclude and grep given a text file or input stream. I generally prefer the most basic one where use two grep where the first one is for exclude with -v option and pipe to second one where I grep for my string. grep -v 'able' config.txt | grep 'system' For more information look https://www.poftut.com/introduction-to-linux-grep-command-with-examples/
