The files should be sorted on the join field.

这些文件应当根据join字段排序。

youdao

If we then sort text2 on its second field and join that with text 5 using the second field of each file as the join field, we should have two matches (apple and banana).

如果我们针对text2的第二个字段对其排序，然后使用每个文件的第二个字段作为join字段来将text2和text5连接起来，那么我们应该得到两个匹配(apple和banana)。

Since text2 is not sorted in numeric order, we could sort it and then join would join the two lines that have a matching join field (the field with value 3 in this case).

由于text2并不是按数值排序的，因此可以对它进行排序并使用join命令将具有匹配的join字段(在本例中指值为3的字段)的两行连接起来。
