如果在file2中找不到file1的输出行
[英]Output line from file1 if not found in file2
问题描述
I need to output the lines from file1 that are not found in file2, ideally using linux commandline. 
我需要从file1中输出在file2中找不到的行，最好使用linux命令行。
Both files are uppercase AZ, sorted, per-file unique, and contain only one word per line. 这两个文件均为大写AZ，已排序，每个文件都是唯一的，并且每行仅包含一个单词。 Typically, file1 is between 5 and 100 lines long, file2 is 250,000 lines long. 通常，file1的长度在5到100行之间，file2的长度在250,000行之间。 Processing speed is not an issue. 处理速度不是问题。
