how do you make a list/file for pacman to install from

I am trying to move from one arch install a (partitioned one) to another (a less-partitioned one) on my computer and I want a simmiler set up. So I was wondering if there was a simple way to get pacman to install the same packages.

I was thinking of something like pacman -Qe | awk '{print $1}' > package_list.txt then creating a script to install from that list. Is there a way I can creat that script in a few comands or how should I go about doing this?
