Hello,

I am new to Unix and hoping that someone could help me with this. I have 2 different text files that has more than 300,000 rows and would like to paste a single column on the File 2 as the very last column of File 1.

Example, File 1:

AAA DDD VVV RRR
AAA DDD VVV RRR
BBB HHH GGG SSS
QQQ ZZZ HHH RRR


File2:

TTT
TTT
TTT
TTT

What I want is:

AAA DDD VVV RRR TTT
AAA DDD VVV RRR TTT
BBB HHH GGG SSS TTT
QQQ ZZZ HHH RRR TTT

I tried to use:
paste -d "\t" file2 file1
but for some reason it got pasted as the first column instead of the last column.
Any help would be greatly appreciated! Thank you so much

you should interchange the filenames

 
paste -d "\t" file1 file2

Why not just:

paste file1 file2

Hello, Thank you for the responses.

I tried both of the codes and it gives me this:
(I am showing you a single line, just a very long sequence. File 1 is shown in blue and file 2 is shown in red)

I don't understand why the file 2 pasted in the middle of file 1, instead of separated by a tab after the very last column of file 1.
