Assign a variable from grep

Question

I'm trying to assign a variable with a value I get from grep, here's my code

a="i 
am
a
string
"
b="$a"|grep am
echo "$b"

I expect the result is am, but the result b is empty. But when I code echo "$a"|grep am directly, I get the right result. why and how can I assign the result to b?

`b=$(echo "$a" | grep am)` – John Kugelman May 09 '18 at 12:36 — John Kugelman, May 09 '18 at 12:36
