You can also do it using -v (for --invert-match ) option of grep as:

(你也可以使用grep的-v （for --invert-match ）选项来--invert-match ：)

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 .

(grep -v "unwanted_word" file将过滤具有unwanted_word的行，而grep XXXXXXXX将仅列出模式为XXXXXXXX 。)

EDIT:

(编辑：)

From your comment it looks like you want to list all lines without the unwanted_word .

(从您的评论看起来您想要列出没有unwanted_word所有行。)

In that case all you need is:

(在这种情况下，您只需要：)

grep -v 'unwanted_word' file
