Combine Multiple text or csv files column-wise
Hi All

I am trying to combine columns from multiple text files into a single file using paste command but the record length being unequal in the different files the data is running over to the closest empty cell on the left. Please see below.
What can i do to resolve this ?
Code:
File 1		File 2		File3 		File4

A		1		X		7		
B		2		Y		8
C		3				9
D		4				10
E		5
		6

Desired Output

Final File
Code:
Column1	Column2	Column3	Column4
    A	            1	            X	            7		
    B	            2	            Y	            8
    C	            3	            9
    D	            4		   10
    E	            5
    6

Current Output
Code:
Column1	Column2	Column3	Column4
A	        1	        X	        7		
B	        2	        Y	        8
C	        3	        9
D	        4	        10
E	        5
6

Your current output and desired output look same.
Also you didn't mention the inputs completely. Pls mention sample of each file content, expected out, current output, the command you are tried.

try using the -d option of paste command to explicitly display another delimiter and check that the right number are paste in the right columns.

(maybe it is just a matter of displaying the tab key)

Code:
paste File1.txt File2.txt File3.txt File4.txt

works for me. You may try:
Code:
paste -d'\t' File1.txt File2.txt File3.txt File4.txt

Not working for me. Did you try with files having different no. of records.

The problem happens when the records in the file on the right are higher than on the file on the left.

When this the case records from right side file spill over to the file on the left like below .

Code:
1  A
2  B
   C

instead of

Code:
1 A
2 B
C
