GAAAAAAAAAAAAAAH I don't know why I'm struggling so much with this.
All I want to do is make:
to make $file=
a [newline] b
And yet no matter WHAT echo or printf I try to use, I cannot get it to work!! I just want a newline between a and b. Can someone bring me out of my misery?
file="$a""echo -e '\n'""$b" does not work, nor can any combination I can think of.
