I am running the following command to get Free Memory, and want to change it from KB to MB to the second decimal.
grep MemFree /proc/meminfo | awk {'print $2*.001'}
Output: 96.163 | Want it to be Output 96.16
How do I round? I have seen where it says to use scale=2, but then it just prints out scale=2, I have tried puttting it before anfer and inbetween several different ways with no luck. how can I do this.
I am editing the .bashrc file to I can see the output in MB no KB
