Ubuntu :: How To Delete Saved Files On Log Out
Apr 11, 2010
I'm setting up a single stand-alone computer in my classroom to be used by my students at the school where I teach. I've installed Ubuntu, as it smashes Windoze out of the court every time.
I want the students to be able to log on to the computer using just one account: 'Student'. This computer will be attached to a printer so they can type up and print oOfice documents,web pages, etc. However, once they log out, I want any files they might have saved (such as a word processed document) to be removed/deleted from the account so that when another pupil logs on to the 'Student' account they start with a clean slate. I suppose you could call it a sort-of Kiosk account.
How can I get Ubuntu to clear any saved documents on log-out?

I am trying to use an old box as backup server. I have tried a couple of possibilities along the lines of:
Quote:
rsync -a --delete --progress --log-file=/home/$USER/info.txt -e ssh /home /etc root@192.168.0.106:/mnt/back
The problem is it does not delete files that has been removed from my local system?
I run the command as root on the local system.
(I realize I should properly not ssh into the server as the server's root but I'm having trouble with the permissions and I want to make sure everything else works before messing around with it)

I just can't stand knowing that there's a slight problem with my PC.I have roughly 12.5 Gigs of files, mostly movies that are multiple clones of a particular movie (which was an entirely different problem altogether) and I CANNOT DELETE THESE THINGS! There has to be a simple way to do it from terminal, problem is, I can't seem to find the trash directory in terminal.

I've had a problem for a while-- when I save files on a USB stick in Ubuntu, then put it in a windows computer, it doesn't recognize the files. It only recognizes a video file that I have, but not the .doc files. The folders either don't appear or only appear as shortcuts.

I'm saving files onto my NTFS partition from Ubuntu (Karmic, dual boot with Vista Home), but, although the files appear to be there, they cannot be read. The error message is 'File not Found. Check the name and try again'. File appears under Windows Explorer and has a file size of 986K.

I just downloaded a file that ends with .Repo, I believe it's a repository file. How should I install this type of file and where/which directory it should be extracted or saved to?
My apology for being a suzee nubbee (Windoz refugee).

I have just had to reinstall my OS (Sabayon) onto a new and larger hard drive (dying old disk). I quickly saved all my old docs in /home on an external USB drive (formatted and then created an ext4 file system) before the swap and installation.
After getting the new disk running I connected the USB external disk. First I could not access the drive at all, but that seems to be fixed. Now I want to bring all my files back to my new /home folder but apparently they (especially the former MS Office .doc, .xls, etc files, not so much the OpenOffice files) are �read only� and I don't have permissions anymore. I am able to create directories on the external, and can move files back and forth, but don't seem to own many of them.Sabayon automatically mounted my external disk in /media/disk, rather than /mnt, so I've left that alone for now. After searching here and elsewhere for info, I tried a few things (below): For access I added a line to /etc/fstab:
Code:
/dev/sdb1 /media/disk ext4 noauto,rw 0 0
Here's what I've done to try and fix ownership already:
in /media I:
Code:
# chmod 775 disk
which gives output of:
Code:
media # ls -l
total 4
drwxrwxr-x 2 root root 4096 Nov 1 21:30 disk
[code]....
I'm not sure what the �total 4� refers to since there is only the one directory �disk� inside /media but I assume that's not part of this issue... Does adding umask=0 have anything to do with this, and if so where does that go?

the permissions for my home directory were accidentally changed from 'access files' to 'create and delete files', and I changed them back, but ever since then I am not able to change any preferences/settings at all. power management, themes, panels, emerald, anything. my user account is supposed to be the administrator, and all the user privliges are checked. how to get control of my computer back?

I noticed in my system that my root partition is getting full. I found a lot of old compacted syslogfiles. Had a look at etc/sysconfig editor eg cron but could not find a setting which allows to delete files older than a month. Where and how could I influence this ? I deleted manually all syslog files older than a month. Approx 6GB

I am using Ubuntu 10.04. I have a small HDD and I noticed that the weight of the folder .Trash-0/lost+found on my computer was of 2.6 gb.
I tried to delete the files in this folder, but it seems impossible. Even with using sudo I can't delete them because I am not authorized to do so. The files in the folder are quite weird, there are folder and files named like this: #7614692, #7613635 etc. Their groups and their users are also quite weird: -1933023744, 1624453254... Even from a live cd it is not possible to delete them. Also the date of the files is ****ed up, example:
- last access: "mar. 13 juil. 1943 15:26:11 CEST"
- last modification: "mer. 12 oct. 2022 15:59:51 CEST"
I recently upgraded this partition from ext3 to ext4, so I would guess that it comes from here. But I don't know if these files where there before or not.

I've got a computer with numerous media files,(video and music). It's a dual boot Windows XP , Ubuntu 10.04 install.I use it as a media box for my large LCD TV. I was wondering if anyone else has deleted the Windows system files and program folders and left the media files. Edit grub deleting Windows XP and leaving the large number of media files alone. I don't want to spend the time to backup and transfer, as it would be to time consuming. I don't want to bork the system just to clean out XP.

I have recently done a clean install of Ubuntu 10.04 [and it is all going very nicely unlike some others] on my dual boot Dell Dimension 5100.After seeing some advice about advanced partitioning I decided to expand my partition table during the 10.04 install process from swap, / and /home (where I keep My Documents) to swap, /, /home, /var, /tmp and /usr, all of which was achieved without problem.I am now getting "Low Disk Space" messages on my home partition (488 MB remaining!!!) I have emptied the trash and cleaned up any obviously large but surplus files. (I did find two that concern me but they aren't HUGE and I am unsure of what they do: file-meta.db and file-index.db in /home/john/.cache/tracker/ which are 290 MB and 108 MB respectively, last modified five months ago and something to do with SQLite3.)
Anyway, am I right in saying that my new /var, /tmp and particularly /usr partitions now contain some of what was previously held on / and /home, leaving old files that can be removed? If so, what is now surplus and how do I delete it safely? I had a bit of a dig but, as the properties in Nautilus of, for example, /usr do not indicate what partition it is on, I can't safely tell what is current and what is old.

Although I've been using Ubuntu for a while, I haven't really done any scripting thus far,but now find myself needing to do (what I thought was) some fairly simple stuff.However, despite much searching, I have been unable to find a solution to my problem.I need a script which will delete all of the files/folders from a directory except those I specify. From the command line, I am able to use:rm -r !(constant|system|*.msh|)
which works fine, deleting everything except the 'constant' and 'system' folders (and everything in them) and any files ending in '.msh'. I have tried to put this into a script file, specifying to use the bash shell, and escaping the required characters, but I just get the message 'cannot find !(constant|*.msh)'.I have read that using the find command may be a better way of doing it, but so far I have not been able to make the command work in the way which I need (I have easily been able to delete ALL the files/folders in the directory!).

I've been organizing my pictures (i.e. deleting the bad ones). However, I've recently got hold of those same pictures on a higher resolution and I'd like to delete the same pictures of the higher resolutions.This means that I'll have two folders, High Res and Low Res. I'd go through all files in the High Res folder and I'll check if there's a file with the same name in the Low Res folder. If there is, the file in the High Res folder will be kept. Otherwise, I'll delete it.So I wanted some quick way to delete PIC1.JPG, PIC3.JPG and PIC4.JPG from the High Res folder.

Update manager was giving me an error that there was not enough free space on /boot. I went in and deleted anything that had 31-14 or 31-15 in the file name (I'm running 2.6.31-19-generic). Will this cause any trouble? I didn't look at my grub file, but does it care if you remove things that it's pointing to that won't get used anyway?
