我想知道如何将两个文件合并到一个列中并删除重复项。先举几个例子。
文件1：
SERVER1; Deployed; Infrastructure
SERVER2; Deployed; Infrastructure
SERVER3; Deployed; Infrastructure
SERVER4; Deployed; Infrastructure
SERVER5; Deployed; Infrastructure
文件2：
SERVER1;
SERVER2;
SERVER5;
期望值：
SERVER3; Deployed; Infrastructure
SERVER4; Deployed; Infrastructure
尝试过类似于：
sort File1 File2 | uniq > File3的命令，但它只返回联接的输出，因为它确实认为每列都是唯一的，输出如下： SERVER1;
SERVER1; Deployed; Infrastructure
SERVER2;
SERVER2; Deployed; Infrastructure
SERVER3; Deployed; Infrastructure
SERVER4; Deployed; Infrastructure
SERVER5;
SERVER5; Deployed; Infrastructure
然后试图从上面得到的命令中删除重复项，但似乎只删除了一行重复项，剩下一行是：
SERVER1;
SERVER2;
SERVER3; Deployed; Infrastructure
SERVER4; Deployed; Infrastructure
SERVER5;
我想检查副本并删除副本和服务器本身，您有什么建议吗？
最佳答案
以下awk可能对您有帮助。
awk 'FNR==NR{a[$0];next} !($1 in a)' File2 File1
