I want to paste one file (with vectos 1xn) in another file? Example:

File1

rs01  rs02  rs03

File2

AA     BB    CC

How I can do this? But in my case, I have 55,000 column in File1 and File2, so, I've been thinking that is difficult to use the command to put head.

The cat utility concatenates all its inputs into one data stream.

Giving it two files, it produces output consisting of the complete contents of the first file, followed by the complete contents of the second file, in that order.

In your case:

$ cat file1 file2 >file-1-and-2

You can try with

cat file1 >> file2

Or you can try the following

while read LINE
do
           echo $LINE >> file2
 done < file1
