Can't get lost in translation then.
BTW thanks.

Code:

#Get Swap size from /proc/swaps
swapsize=$(awk '{if ($1=="'"/dev/$disk"'") print $3}' /proc/swaps)
#Divide by 1024 to get swap size in megabytes
swapsizembytes=$(($swapsize/1024))
...snip...

Here it is okay to divide by 1024
I spoke about getting number of blocks from /proc/diskstats. Each block is 512 bytes.
You have to divide by 2 to get kB.
And then of course by 2048 to get MB.

Code:

[B]umbytes=$(($ublocks/2048))

And forget about bytes and kbytes here.

To make it bullet proof:

Code:

echo $ublocks ublocks
#Multiply blocks by 512 to get used bytes
#ubytes=$(($ublocks*512))
#Calculate used bytes into Kb, Mb and Gb
echo $ubytes ubytes
#ukbytes=$(($ubytes/1024))
##ukbytes=$(($ublocks/2))
##umbytes=$(($ukbytes/1024))
umbytes=$(($ublocks/2048))
#ugbytes=$(($ubytes/1024/1024/1024))
ugbytes=$(($umbytes/1024))

And of course rely only on umbytes from this line on in your code (needs review which I did not do

I also use swappolube with (almost) default settings.

Yes.

But it is unrealistic to think anyone will ever reach TB swap usage on N900, or? (remember the 2k date time problem?

)
