Been a while since I used persistence, but if my memory serves me correctly, you need to find out the size of the image in the save,dat file.

@ anandisrocking007
as root:
mloop /path/savefile.dat

Filemanager > /mnt/loop

I don't know if one can do this when the savefile is in use.
(I don't have one)

when finished type uloop

Been there done that but it mounts it does not tells the exact amount of data used also i was thinking of asking this in another thread it seems i can use the mloop command to read iso file,dat file which have been used as magic folder but it seems that i can not use this for the persistant sav.dat file it comes up empty for some reason and but i know there are settings saved in it

I understand. Been there, done that. Save this script to your /home/guest/ folder:

savedatspaceused.sh

Code: Select all

rst=$(tput sgr0)                  # Reset

function redpswd() {
  echo -e "$1" $txtred  
}

if [ `whoami` != "root" ]; then
    redpswd "Enter root's password"
    su -c "sh $0 $1"
    exit
fi
echo $rst

if [ -a /mnt/live/memory/images/changes ]; then
   SPACEDATDIR=/mnt/live/memory/images/changes 
fi

echo
echo du -sh
du -sh ${SPACEDATDIR}     # Show the amount used

@ anandisrocking007
sorry,my bad
you have to reboot into the "allways fresh" mode to make it work.(mloop the save.dat)

hmm..doesn't a df -h /mnt/live/memory/changes/
(normal boot) show the save file values.?

Thanks a lot in telling me that you can only loop the save.dat file in freshor copy2ram mode i thought i was doing something wrong they should add this line in the the porteus tutorial. But the df -h /mnt/live/memory/changes/ does not show the value i think it shows the amount of memory used in ram or so

yours only this command say the size of the save.dat file filled
mloop /mnt/sdb1/porteus/save.dat

guest@porteus:~$ df -h /mnt/loop/
Filesystem Size Used Avail Use% Mounted on
/dev/loop5 509M 37M 473M 8% /mnt/loop

Overall thanks a lot you guys for the reply now found out that 90% of my save.dat was being eaten by the google chrome cache i guess the best way is Ed_p 's Script
