well, i'm trying to allocate a limit of, let say 100mb per user account....
are there such commands for me to do so?

Of course.
No problem at all.
It has been there since the time of RH6.

Very straightforward.
Buckle your seatbelt.
Here we go!

0)Log in as root.

1)Edit file /etc/fstab to add the word "usrquota" to the partition.
Eg:-
dev/hda2 / ext3 defaults,usrquota

2)Make a blank file "aquota.user" to output the quota report. Make it so only root can access it.
touch /aquota.user
chmod 600 /aquota.user

3)Remount the partition (to apply the changes we made to fstab)
mount -o remount /

4)Record the partition information into the aquota.user
quotacheck -vguma

5)enable disk quotas on a file system -> quotaon
turn off disk quotas for a file system -> quotaoff

6)Edit user quota based on user_id -> edquota -u user_id

7)Display quota information for user_id -> quota -u user_id

If you're not sure about each command, use man commandname to check out the available parameters for each command.

Might want to add quota check procedures into the cron

My example is based on the partition "/"..
You can put the quota on any other partition..

u may use control panel to do so, like webmin or plesk

E325: ATTENTION
Found a swap file by the name ".fstab.swp"
owned by: root dated: Wed Jun 15 15:51:34 2005

(1) Another program may be editing the same file.
If this is the case, be careful not to end up with two
different instances of the same file when making changes.
Quit, or continue with caution.

(2) An edit session for this file crashed.
If this is the case, use ":recover" or "vim -r fstab"
to recover the changes (see ":help recovery").
If you did this already, delete the swap file ".fstab.swp"
to avoid this message.

Swap file ".fstab.swp" already exists!
[O]pen Read-Only, (E)dit anyway, ®ecover, (Q)uit, (D)elete it:

well, i use the non-gui interface...
anyhow, i wanna try ur method yesterday by going "vi fstab".
half way, the screen went cacat (i guess tat's because i use the scroll mouse). i'm not sure if i accidentally type wrong or anything. to avoid any error, and i jst quit on the the cygwin by clicking on the X button at the top right..
when i try to open back again "vi fstab", i have the error above..
any idea what i should do? i dont want to overwrite the original file.

Did you edit anything prior to the crashing?
If you have edited something prior to the crashing, then choose recover in this window.
If you're sure that there's no difference between the two fstab, just remove that fstab.swp
This is just a normal situation when the system crashed while we are editing files using vi.

If you're not sure of something, remember to do backup of the file first before making any changes.
I'll be around if you need any help.

Cheers.

i'm not sure if i edit or anything or not...ok..assuming that i've edited it, but i dont want the new copy..i want back the original copy (the one be4 i edit)...which option i should choose?
-recover? (meaning?)
-quit?
or
-delete (meaning del the new file or the original one?)

Since you are not sure also, just delete that *.swp file.
Usually if we don't issue wq in vi, it won't be saved.
Cheers.

i c...so kons, correct me if i'm wrong..

-recover -> to use the edited one to overwrite the original copy (something like microsoft word, to restore back the last saved file?)

-quit -> i stil dunno what this for

-delete -> to del the edited version, while maintaining back the original fstab file in the server?

Hey, that's right.
Btw, I didn't know that you're using cygwin.
Hope it works well.
Cheers!

P/S: Quit is for ignoring everything and quit the vi editor. Wont make any changes.

i c...so for this case (since i'm using cygwin), i can choose either quit or del the file lah...cause my main concern is maintaining my original file mah for fstab..

Bear in mind that the edited file is in the *.swp file.

Cheers

i c....so, can i say that for all VI edited file, if the system hanged or reboot, it will auto saved into swp files?

That's right.

Cheers!
