如何将多个文件逐行合并为一个文件?

How to merge multiple files into one line by line?

我有 4 个文件

**File1**          **File2**        **File3**        **File4**
alpha              this             security         rain 
beta               that             performance      go 
gamma              an               auto             away
.                  .                .                .    
.                  .                .                .
.                  .                .                .
[25000 rows]       [25000 rows]     [25000 rows]     [25000 rows]

我希望这 4 个文件在结果文件中合并为 结果文件

alpha
this
security
rain
beta
that
performance
go
.
.
.
[75000 rows]

我如何在 vi 中做到这一点?

使用paste:

paste -d "\n" file1 file2 file3 file4
