Bsh - new line not interpreted with printf and "echo -e"

I would like to generate 2 values columns (actualy (x,y) for y=x^2 function).

So I did under Bash:

echo $(for((i=0;i<100;i++)); do printf "%3d %3d\n" $((i)) $((i*i)); done)

But I get a single row with (i,i*i) sequence, not 2 columns.

I tried to add "-e" option for echo, but this doesn't work too.

If someone had a trick, this would be fine.

You're... echoing the output from printf? – Ignacio Vazquez-Abrams Mar 28 '17 at 05:11
Go figure... Remove the `echo $(` and the ending `)`. – David C. Rankin Mar 28 '17 at 05:12
That's a common antipattern actually. See [useless use of `echo`](http://www.iki.fi/era/unix/award.html#echo). – tripleee Mar 28 '17 at 05:15
Thanks ! didn't know that was useless – Mar 28 '17 at 05:24
