free -g

echo 3 k $(cat /proc/meminfo | grep MemTotal | awk '{print $2}') 1024 / 1024 / p | dc

make sure you have dc (desk calculator) installed.

Why not use bash's built-in math functionality?

Code:

$(( $(cat /proc/meminfo | grep MemTotal | awk '{ print $2 }') / 1024 ))

AFAIK Bash has no built-in math functionality except integers.

Yes, bash only does integer math.
