我有一个包含ID列表的文件,如
File1.csv
123456
1234234
2324324
325435345
和其他文件结构是这样的:
File2.csv
1234234,asadasdas!w2eaesfd+smakdnjads,"points-ka"
2131231,sadfasfa990-0;;'.sadsadsada,"points-ka"
2324324,asadasdas!w2eaesfd+smasdasdfadewe,"points-ka"
5434234234,adasdfsfhguse38873h78hu8i8377&*&*,"points-ka"
现在,我想使用此命令加入文件
加入-t,file1.csv file2.csv
但是这不是我输错的地方的任何输出吗?
必需输出:
1234234,asadasdas!w2eaesfd+smakdnjads,"points-ka"
2324324,asadasdas!w2eaesfd+smasdasdfadewe,"points-ka"

在加入之前,必须在连接键上对文件进行排序。
sort file1.csv > file1sorted.csv
sort file2.csv > file2sorted.csv
join -t, f1s.csv f2s.csv
1234234,asadasdas!w2eaesfd+smakdnjads,"points-ka"
2324324,asadasdas!w2eaesfd+smasdasdfadewe,"points-ka"

连接的必要条件是文件应该先排序。
$ sort File1.csv > File1.sorted.csv
$ sort File2.csv > File2.sorted.csv
$ join -t, File1.sorted.csv File2.sorted.csv
1234234,asadasdas!w2eaesfd+smakdnjads,"points-ka"
2324324,asadasdas!w2eaesfd+smasdasdfadewe,"points-ka"
