Display the memory in Gb, Mb and Kb

[guif]

I would like to make a script (bash) to display the memory in GB, MB and KB.

For example, If I take 1049132Mb, the result are:

1GB, 5Mb and 0 Kb

Is it possible to make it??


thanks!

Of course it is possible. You can use "free", or "vmstat" or "cat /proc/meminfo" to get an overview of memory use, for example, and the operators "%" and "/" to split the result into appropriate chunks.

I have this:

MEMTOTAL=`free | grep Mem | awk '{ print $2 }'`
MEMUSED=`free | grep Mem | awk '{ print $3 }'`
MEMFREE=`free | grep Mem | awk '{ print $4 }'`

echo "Total: "`expr $MEMTOTAL / 1048576`"Gb"
echo "Used: "`expr $MEMUSED / 1024`"Mb" "($MEMUSED Kb)"
echo "Free: "`expr $MEMFREE / 1024`"Mb" "($MEMFREE Kb)"

but i don't know to split and convert to my idea...

If you use free with the switches -k -m -g it will give you the output you desire, there is more info on the switches you can use in the man pages for the free command.

but i necesary to split the result...

Yes, but that's just elementary math.
