shell - Linux command for physical memory, getting the value only -


in linux cat /proc/meminfo | grep memtotal gets memtotal: 12298824 kb

i want numbers here

so wrote cat /proc/meminfo | grep memtotal | cut -d':' -f2 gave me 12298824 kb

i want numbers here, can me?

note: cat /proc/meminfo | grep memtotal | cut -d':' -f2 | cut -d'k' -f1 gives me solution 12298824, there better way? 1 liner?

use awk:

cat /proc/meminfo | grep memtotal | awk '{print $2}'

from @lars wirzenius's comment(no cat , no grep):

awk '/memtotal/ { print $2 }' /proc/meminfo
