You are indeed right. It looks like an asterisk, and it couldn't be a typo owing to distance between keys, So must have crept in during editing, when a line was lost.
Anyway here it is Jack, completely tested and enhanced, so should be working

@ Jack
This time you did do wrong.
You had to copy the updated mksavfile.sh from
Re: Save.dat / changes confusion (Post by Jack #47965), then there would not be the error with mkdir. The file that was made looks fine. To use the file, it has to be moved to a real filesystem.
Clearer
mksavfile.sh:

That's right. You have to delete it first. Anyway try the mksavfile.sh that I put up today.

Hi Jack
It is just that the output has been made clearer to read. Should make more sense with latest version.

@ Jack
That's just fine. You can try
to get rid of f15556, if you like. Don't know why it could not be dismounted.

So were on the same page. If you need me to test any thing more please post it. But it seem to me it works.
I just ran this.
Code: Select all
root@porteus:/home/guest/Documents# umount -f f15556
root@porteus:/home/guest/Documents# rmdir f15556
root@porteus:/home/guest/Documents#
What do I need to look for?
EDIT:
Is this one the most current # 12.08.2016 and the one to use?

Jack, you don;t need to run mksavfile.sh it as root, Now you need to move it to a real file system, and use it to save changes in. Let us know how you get on.

I just built a USB to try it. After I ran the script I had to reboot to make it work. Here is the output.
Code: Select all

We trust you have received the usual lecture from the local System
Administrator. It usually boils down to these three things:
#1) Respect the privacy of others.
#2) Think before you type.
#3) With great power comes great responsibility.

How can I check how much has been used after I added info?
I just like Slackware because I think it teach you about Linux to build packages where Ubuntu is like Windows you just install programs you want.

Code: Select all
mkdir s; sudo mount /mnt/sdb1/porteus/porteussave.dat s
du -sh s # Amount that has been used by you
df -h s # Think shows used by you and the XFS filesystem. Not sure though.
In your example it is showing 246M available.
Looking at the result you had here
http://forum.porteus.org/viewtopic.php? ... 987#p47978 you will see there is a difference with the one done on usb:
- One you did earlier;
Code: Select all
root@porteus:/home/guest/Documents# sh mksavfile.sh myfile.dat 256
...
ls -lh myfile.dat
-rw-r--r-- 1 root root 256M Aug 12 08:03 myfile.dat
...
file myfile.dat
myfile.dat: SGI XFS filesystem data (blksz 1024, inosz 512, v2 dirs)
ls -sh myfile.dat
2.8M myfile.dat
du -h myfile.dat
2.8M myfile.dat
- One done on usb
Code: Select all
guest@porteus:~/Downloads$ sh mksavfile.sh /mnt/sdb1/porteus/porteussave.dat 256
...
ls -lh /mnt/sdb1/porteus/porteussave.dat
-rwxrwxrwx 1 root root 256M Aug 12 12:08 /mnt/sdb1/porteus/porteussave.dat
...
file /mnt/sdb1/porteus/porteussave.dat
/mnt/sdb1/porteus/porteussave.dat: SGI XFS filesystem data (blksz 1024, inosz 512, v2 dirs)
ls -sh /mnt/sdb1/porteus/porteussave.dat
256M /mnt/sdb1/porteus/porteussave.dat
du -h /mnt/sdb1/porteus/porteussave.dat
256M /mnt/sdb1/porteus/porteussave.dat
This is all a bit strange. You should have made a file on the usb with owner guest, however it says owner is root.
Can we try something here please. Is sdb2 formatted ext4 or ntfs?
Code: Select all
sh mksavfile.sh porteussave.dat 256
sudo mkdir /mnt/sdb2/Test
sudo chmod a+rw /mnt/sdb2/Test
ls -ld /mnt/sdb2/Test
mv porteussave.dat /mnt/sdb2/Test
ls -lh /mnt/sdb2/Test/porteussave.dat
ls -sh /mnt/sdb2/Test/porteussave.dat
du -h /mnt/sdb2/Test/porteussave.dat
Test by using
changes=/dev/sdb2/Test/porteussave.dat

I can tell you I'm lost on your last message. Is there a script you ca write that will help?

My sdb1 is formated fat32.
