how to print output of mutiple files side by side

I have 4 files say:

cat test1
1 
2   
3

cat test2
4  
5  
6  

cat test3
7  
8  
9

I need to display the content as below side by side:

1  4  7  
2  5  8  
3  5  9

I tried pr -m -t test1 test2 test3, but if if any value is large, the output is getting trim, I need to display the content according to the length of the value and should display the content side by side(column wise)

Give a try to paste, for example:

$ cat test1 test2 test3 | paste -d " " - - -

From the man:

If - is specified for one or more of the input files, the standard input is used; standard input is read one line at a time, circularly, for each instance of -.

So if you don't care about the order and let's say you would like to use all your *.txt files, you could simply do:

$ paste -d " " *.txt

You could also use lam:

$ lam test1 -s " " test2 -s " " test3

Both examples use space as the separator " " and will output:

1 4 7
2 5 8
3 6 9

You can use this command which would not truncate the column values while printing:

pr -mJ test1 test2 test3 --sep-string=" || "

You can simple do it like :

cat *.txt | paste -d " " - - - | sed 's/_//g'

to complete nbari according your question: paste test1 test2 test3 | column -t

P.S. for column greater than your screen size: paste test1 test2 test3 | column -t| less -S
