打印一个文件中不包含在另一个文件中的行
问题描述:
我希望打印在一个文件中但不在另一个文件中的行.但是,两个文件都没有排序,我需要保留两个文件中的原始顺序.
I wish to print lines that are in one file but not in another file. However, neither files are sorted, and I need to retain the original order in both files.
contents of file1:
string2
string1
string3
contents of file2:
string3
string1
Output:
string2
有没有我可以在其中完成此操作的简单脚本?
Is there a simple script that I can accomplish this in?
答
fgrep -x -f file2 -v file1
-x 匹配整行
-f FILE 从 FILE 中获取模式
-f FILE takes patterns from FILE
-v 反转结果(显示不匹配)
-v inverts results (show non-matching)
