Bash script to read free RAM

[aksd]

Hello all,

I requried a spot of help. I need a bash script to read only the free RAM from the command free and store it in a variable. I know we need to use awk or gawk, but I'm unsure on the syntax.

This does'nt seem to be working on the E6 :

echo "$( free -mto | grep Mem: | busybox awk '{ print $4 " MB" }')"

Is this what you want?

my_var="$( free -m | grep Mem: | busybox awk '{ print $4 " MB" }')"

[aksd]

Let me test it out and get back to you . Thanks.
