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.

Re: Save.dat / changes confusion
How can I tell how much been used? That 4GB has 2.4 free. One thing I did was I made a copy of porteussave.dat file and put it here "/mnt/sdb1/backup" backup is a directory on the same USB just to be safe.

Re: Save.dat / changes confusion
An excellent question Jack. And it is good to be concerned because a) it can fill up and b) you can loose your files should it fill up.Jack wrote:How can I tell how much been used?
If you are using the save.dat file these commands should help:

Re: Save.dat / changes confusion
I should look at implementing this in the shutdown scripts. If there is not enough room then the changes are not saved in order to prevent the container file from becoming corrupt.
How do i become super user?

By all means leave it named as porteussave.dat. save.dat is just it's nickname.Jack wrote:Should I rename mind to save.dat or is it ok to leave mind porteussave.dat?
![Smile :)](./images/smilies/smile.gif)
Well I would try the 1st script periodically to get a feel for the space usage. See how it's allocated and such.And do I use the 2nd script so it will auto do it for me?
Did you save the script as that name? And where did you save it? Mine is in my /home/guest/ folder.EDIT:
This what happen.You might need some kind of built in Help but just a idea.Code: Select all

You don't need to added "porteussave.dat" to the commands to run them. Both scripts read the contents of the files in use.
For the automatic check version this is my /etc/rc.d/rc.local_shutdown file:
Code: Select all
#!/bin/sh
#
# rc.local_shutdown
#
# This script is executed at shutdown (rc0) and reboot (rc6).
# You need to make it executable before using.
#
# Example:
# /etc/rc.d/rc.samba stop
#
/home/guest/savedatspaceck.sh

Re: Save.dat / changes confusion
save.dat file 33% full. Used: 164M Free: 346M
There is something wrong with the math here.
Thank you. I am honored you would consider an idea of mine.
The idea was introduced many years ago, but sat on the backburner. Thanks for bringing it back up, and thanks for the legwork Bogomips. If time permits I will try to incorporate it into the shutdown. Perhaps if the container is not big enough an offer could be made to create a module on a real file system instead.

Not by much.brokenman wrote:save.dat file 33% full. Used: 164M Free: 346M
There is something wrong with the math here.
164 / (164 + 346) = 164 / 510 = 0.321568
And the numbers are from Porteus's df command not calculated by a script.
Yes. Thank you. Or offer to stop the shutdown and let the user decide how to proceed.Perhaps if the container is not big enough an offer could be made to create a module on a real file systemr instead.
I was considering adding a 15 second delay to the warning to allow the user time to consider a plan of action.

Re: Save.dat / changes confusion
Another approach could be to change the way the save.dat file is created, as illustrated thru dabblings with container file http://forum.porteus.org/viewtopic.php? ... 800#p47800. In the example the amount of free and used space is always ascertainable offline.brokenman wrote:If time permits I will try to incorporate it into the shutdown.

Re: Save.dat / changes confusion
Pardon me but that approach is something the user has to run manually and it may not be done when most needed, when shutting down.Bogomips wrote:Another approach could be to change the way the save.dat file is created, as illustrated thru dabblings with container file http://forum.porteus.org/viewtopic.php? ... 800#p47800.

I've used this script for a few years now to manually check my save.dat space files both online and offline. And it works for versions 3.0, 3.1 and 3.2 rc3, 4 & 5. But it only works if you remember to use it.
