[SOLVED] How to find out the space used in save.dat file

[anandisrocking007]

Hi everyone i guess the topic tells it all i have made a save.dat file but lets say i saved to much it and it became full or i made a made a magic folder and linked it to a folder in porteus can you show me a way to findout how much space i have used in the save.dat file would appreciate an answer.....

i dont know, it use ext4 formatted drive, and i think its better for porteus than fat32

[anandisrocking007]

Thats true but once the the datfile gets full then it would cause problem

[Seva]

when using ext4 there is no .dat containers, everything becomes better

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

Well can you help me with that i have heard you have to type some commands in the terminal any idea what those are would help a lot as for the ext4 i would prefer to keep it windows readable and it would not heart if i learnt something along the way......

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

@ 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.?

[Bogomips]

Code: Select all

guest@porteus:~$ df -h /mnt/live/memory/changes/

@ Ed_P thanks a lot your script is awesome and it told precicely what i wanted to know
Here is the result of the script

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

Code: Select all

guest@porteus:~$ df -h /mnt/live/memory/changes/ 
Filesystem      Size  Used Avail Use% Mounted on
-               265M  4.0M  261M   2% /mnt/live/memory/changes
guest@porteus:~$ df -h .
Filesystem      Size  Used Avail Use% Mounted on
aufs            265M  4.0M  261M   2% /

cpy2ram and not using changes, Get same values.

Nope thats not it checked it Ed_P 's script gives the right value

@Bogomips
normal boot with save.dat (save changes)

guest@porteus:~$ df -h /mnt/live/memory/changes/
Filesystem Size Used Avail Use% Mounted on
- 509M 37M 472M 8% /mnt/live/memory/changes

root@porteus:/home/guest# du -sh /mnt/live/memory/changes/
11M /mnt/live/memory/changes/

copy2ram without save.dat (also allways fresh)

guest@porteus:~$ df -h /mnt/live/memory/changes/
Filesystem Size Used Avail Use% Mounted on
- 606M 408K 605M 1% /mnt/live/memory/changes

root@porteus:/home/guest# du -sh /mnt/live/memory/changes/
408K /mnt/live/memory/changes/

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

root@porteus:/home/guest# du -sh /mnt/loop/
11M /mnt/loop/

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
