Any command to list the memory in MB rather than kB from /proc/meminfo?

Cat, less , more , head tail etc. tried with all options that I am aware of. Can't find how to list the memory in Megabytes rather than kB.

Can't find how to list the memory in Megabytes rather than kB.

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

In bash you may do it this way

#! /bin/bash kb-to-mb() { echo $1" "$(( $2 / 1024))" "MB } exec < /proc/meminfo while read a b c do if [ o$c = "okB" ] then kb-to-mb $a $b $c else echo $a $b $c kb-to-mb $a $b $c done | column -t
