我有这样的文件file-1:
1 1 1.1552422143268792
1 2 1.1552422143268792
1 3 1.1552422143268792
1 4 1.1552422143268792
2 1 2.1906014042706916
2 2 2.1906014042706916
2 3 2.1906014042706916
2 4 2.1906014042706916

4 2 0.6213184222668061
4 3 0.6213184222668061
4 4 0.6213184222668061
我还有一个文件 file-2
1
2
4
我想从 file-1 中过滤那些记录，其中第一列的值与 file-2 中的值相同，所以我想得到这个输出
1 1 1.1552422143268792
1 2 1.1552422143268792
1 3 1.1552422143268792
1 4 1.1552422143268792
2 1 2.1906014042706916
2 2 2.1906014042706916
2 3 2.1906014042706916
2 4 2.1906014042706916
2 1 4.1906014042706916
2 2 4.1906014042706916
2 3 4.1906014042706916
2 4 4.1906014042706916
4 1 0.6213184222668061
4 2 0.6213184222668061
4 3 0.6213184222668061
4 4 0.6213184222668061
有人可以帮忙吗？
最佳答案
awk 'NR==FNR{f2[$1];next}$1 in f2' file-2 file-1
