我怎样才能用grep排除一个单词？ [英] How can I exclude one word with grep?

问题描述

我需要这样的：

  grep ^unwanted_wordXXXXXXXX 
  

解决方案

您也可以使用 -v 选项grep as：

  grep -vunwanted_wordfile | grep XXXXXXXX 
  

grep -vunwanted_wordfile 将过滤具有 unwanted_word 和 grep XXXXXXXX 的行将仅列出具有 XXXXXXXX 。

编辑：

注释它看起来像你想列出所有行，而不是 unwanted_word 。在这种情况下，所有你需要的是：

$ p $ grep -v'unwanted_word'文件


I need something like:

grep ^"unwanted_word"XXXXXXXX

解决方案

You can also do it using -v option of grep as:

grep -v "unwanted_word" file | grep XXXXXXXX

grep -v "unwanted_word" file will filter the lines that have the unwanted_word and grep XXXXXXXX will list only lines with pattern XXXXXXXX.

EDIT:

From your comment it looks like you want to list all lines without the unwanted_word. In that case all you need is:

grep -v 'unwanted_word' file
