文件 1 只有一列，我正在使用命令 sort -n file1

对文件进行排序

文件 2 具有三列，我正在使用命令 sort -t ","-k 1n,1 file2 对文件进行排序，该命令基于 ist 列进行排序。

现在，我想找到 file2 中从 file1 中的行开始的行

我尝试过的命令:

grep -w -f file1 file2

join -t "," -1 1 -2 1 -o 2.2 file1 file2

但是，我没有得到想要的结果。请给我提供替代方法。文件 1 有行 7124458，文件 2 有行 42987432。

Answer 1

使用 awk:

awk -F, 'FNR == NR { ++a[$0]; next } $1 in a' file1 file2

输出:
