Unix-使用Grep获取不匹配的行
问题描述：
我是unix的新手.我想从文件1中复制不匹配的模式，前提是这些模式在文件2中.实际文件有1000行以上.
I am new to unix. I want to grep the unmatched pattern from a file1 provided that the patterns are in the file2. The real files are having more than 1000 lines.
示例:
File1:
Hi(Everyone)
How(u)people(are)doing?
ThanksInadvance
File2:
Hi(Every
ThanksI
必填结果:
How(u)people(are)doing?
我只希望使用grep的模式("Hi(Every").它应该从file1返回不匹配的行.
I want only the pattern to be used like ("Hi(Every") for the grep.It should return the unmatched line from file1.
答
此行适用于给定示例:
grep -Fvf file2 file1
上面使用的3个选项:
-F makes grep do fixed-string match
-v invert matching
-f get patterns from file
