grep -v文件中的多个字符串

Question

我有2个文件:

1. 文件1

字符串列表:

ben
john
eric

1. 文件2

几行:

 ben when to school
 my mother went out
 the dog is big
 john has FB
 eric is nice guy

expoted文件:

my mother went out
the dog is big

我想使用grep -v并删除列表中包含字符串的行.

这是想法,但错误的命令:

grep -v `cat file2` file1 > out

谢谢

Answer 1

使用文件模式:

grep -v -f "file2" file1 > out

或者你可以这样做:

grep -v -e "string1" -e "string2" file1
