How to display /proc/meminfo into Megabytes

Question

I want to thank you for helping me my related issue. I know if i do a cat /proc/meminfo it will only display in kb how can i display in mb ? I really want to use cat or awk for this please.

Answer 1

This will convert any kB lines to MB:

awk '$3=="kB"{$2=$2/1024;$3="MB"} 1' /proc/meminfo | column -t

This version converts to gigabytes:

awk '$3=="kB"{$2=$2/1024^2;$3="GB";} 1' /proc/meminfo | column -t

For completeness, this will convert to MB or GB as appropriate:

awk '$3=="kB"{if ($2>1024^2){$2=$2/1024^2;$3="GB";} else if ($2>1024){$2=$2/1024;$3="MB";}} 1' /proc/meminfo | column -t
