How to print out size of physical memory in linux

If I use this grep MemTotal /proc/meminfo in linux terminal, I get MemTotal: 2059908 kB.

Does anybody know how to get numbers only? which will be 2059908?

One way is to filter the output with something like:

grep MemTotal /proc/meminfo | sed 's/[^0-9]//g'

This will remove all characters that aren't digits, as per the following transcript:

pax:~$ grep MemTotal /proc/meminfo
MemTotal:        4122788 kB

pax:~$ grep MemTotal /proc/meminfo | sed 's/[^0-9]//g'
4122788

Try adding this: |awk '{print $2}'
