General :: Ubuntu 10.04 - Tar Command To Archive Home Directory
Sep 3, 2010
Ubuntu 10.04. As part of my nightly backup script I archive my home directory with the following command
tar -cvpzf /quitelarge/_mirror/mirror1/home-ken.gz /home/ken 2>> /quitelarge/_mirror/tar-error.log
It seems to work fine and I have recovered files from the archive on occasion. Actually I keep 7 rolling daily backups and a monthly burn to DVD. I had an sftp connection made by Nautilus to my server. Ubuntu for whatever reason places an icon on the desktop showing the connection. When I ran the script it decided to archive everything on my server - all 1.4 TB. I caught the problem when home-ken.gz was about 5 GB. I stopped the process, closed the sftp connection, rolled back the backups and tried again. This time I got a file of the expected size - about 45 MB.
In the error log I did find that the tar process was trying to suck the entire contents of the server into the archive file.
tar: /home/ken/.gvfs/sftp for ken on taylor10/proc/asound/ICH5/pcm0c/sub0: file changed as we read it
tar: /home/ken/.gvfs/sftp for ken on taylor10/proc/asound/ICH5/pcm0c: file changed as we read it
tar: /home/ken/.gvfs/sftp for ken on taylor10/proc/asound/ICH5: file changed as we read it
tar: /home/ken/.gvfs/sftp for ken on taylor10/proc/asound: file changed as we read it
tar: /home/ken/.gvfs/sftp for ken on taylor10/proc/scsi: file changed as we read it
tar: /home/ken/.gvfs/sftp for ken on taylor10/proc/acpi/event: Cannot open: Permission denied
tar: /home/ken/.gvfs/sftp for ken on taylor10/proc/acpi/fadt: Cannot open: Permission denied
tar: /home/ken/.gvfs/sftp for ken on taylor10/proc/acpi/dsdt: Cannot open: Permission denied
tar: /home/ken/.gvfs/sftp for ken on taylor10/proc/irq/21/smp_affinity: Cannot open: Permission denied
Is there an option I can place on the tar command to tell it NOT to follow the ssh connection which is sitting on my desktop? The closest thing I see in the documentation is -h which tells tar to "follow symlinks; archive and dump the files they point to." I am NOT specifying -h so if the ssh connection is treated as a symlink by tar I would still not expect the remote contents to be tarred.

I have been playing around with the tar command and I know this is how to use it.
Code:
tar -cf [filename] [directory]
But what I want to make an archive from the current directory I thought just to not enter a directory but that doesn't work. I get an error about creating a empty archive so how to do I make it so how do I tell it to do the current directory?

Why would rsync insert a user's home directory path in variable expansion when run via cron, but not when run manually. The gory details... Red Hat Enterprise Linux AS release 4 (Nahant Update 6) Linux 2.6.9-67.0.20.ELsmp The script (parts anyway, and simplified)...

#!/bin/bash

I have an interdependent collection of scripts in my ~/bin directory as well as a developed ~/.vim directory and some other libraries and such in other subdirectories. I've been versioning all of this using git, and have realized that it would be potentially very easy and useful to do development and testing of new and existing scripts, vim plugins, etc. using a cloned repo, and then pull the working code into my actual home directory with a merge.
The easiest way to do this would seem to be to just change & export $HOME, eg
cd ~/testing; git clone ~ home
export HOME=~/testing/home
cd ~
screen -S testing-home
# start vim, write/revise plugins, edit scripts, etc.
# test revisions
However since I've never tried this before I'm concerned that some programs, environment variables, etc., may end up using my actual home directory instead of the exported one. Is this a viable strategy? Are there just a few outliers that I should be careful about?

I have a directory that contains some files. Let's call it ./ActiveContent.
I have a tar ball that contains some updated files, let's call it updates.tar.gz.
How do I unpack updates.tar.gz in the directory ./ActiveContent so that files in updates.tar.gz overwrite the identical named files in the directory?
That is to say, an option that directs the utility to over write existing files wile expanding a tar archive into a directory?

I want to untar a package from one directory to another directory, directly from the command prompt. I want to untar the joomla package into the htdocs directory of xampp. How to do that directly from command prompt ? The reason i am asking this is if I try the "drag and drop" way, it won't be possible as xampp is stored in /opt directory and without super-user authentication nothing can be saved into it. You can argue saying that why did I untar xampp initially in su mode ,but that had to be done so that apache doesnt give me any start-up problems.

I am here with a troublesome question about my new Ubuntu set up. Well as I've found out that you have to use the Sudo command to edit anything out side the home directory. Well I am using L.A.M.P. Server on my computer so I can host a small forums. Well for example like lets say I install Word press Blog onto my lamp server and I want to install a theme well when i go to install a theme i can not because WPB can't install the theme because of the security stuff on Ubuntu!
Well I want to know if there is some kind of command or program i can use that will get rid of all the security stuff were i can edit stuff nice and easy. Like something that can give me FULL control over the OS so no more commands because I am going to be running a Vbulliten forums which needs themes and plug ins, well i want be able to install them because this OS will not let me!

I have a secondary disk which holds a /home directory structure from a previous install of Linux. I installed a new version on a new primary drive and mounted this secondary drive as the new /home. Problem is, even though the users are the same names and I can access the home directories for the users, I cannot login directly to their home directories, as I get the following error: -
Code:
login as: [me]
[me]@[machine]'s password:
Last login: Wed Jan 6 18:34:33 2010 from [machine]
Could not chdir to home directory /home/[me]: Permission denied
[[me]@[machine] /]$
Now, since the usernames are correct and the users are in the passwd file with the correct home directory paths, could it be user ID's that are different or something else? It's not as though I cannot access the home directories for the users, simply that I cannot log directly into them from a login prompt.

Is there anything special about a home directory before users' home directories are stored there, or is just as typical as any other "empty" folder?Let me just cut to the chase, but please no ear ringing about the folly of messing around as root, particularly with directories at root level. I know it's considered stupidity, but I deleted my home directory.
Is there an easy way to restore a working home directory? I tried copying /etc/skel under root, but I'm not sure what a home directory should look like once it has been restored. Besides . & .., there were .screenrc & .xsession in my home directory when I copied /etc/skel. Are these files suppose to be in "/home" or "/home/~" or both?

I'm using Mac OS X's Terminal.app shell to compile and run Fortran programs. One such program resides outside of my home directory (it is in the Applications folder, which resides on my hard drive but seems to be outside of my home folder). How can I navigate into this directory using Terminal.app to run the programs that reside there?

I am a student studying computer science course.
Well, I am facing problem when doing lab questions.
I must use DLXLinux bundled in Bochs (bochs.sourceforge.net).
I am required to use the /usr/local directory.
In /usr directory, there is no directory named 'local' but there is one thing called 'local@'. So, when I try to use mkdir command to create 'local' directory in /usr , there are error "cannot make directory.....".
Look at my screenshot at [url].

I'm taking a very large collection of music and also newly purchased anime DVDs and adding them to another large existing collection, basically hundreds of ogg/mp3 and OGV-type files on a jukebox system to serve to my PS3 via mediatomb. (No, I'm not handing out copies and risking the feds at my door! I'm just trying to save my CDs and DVDs from ruin by over-replaying.)
My problem is I want to save electricity and minimize my carbon footprint but also I need a LOT of terabytes for what I have and what I will have, since these are going to be DVD quality (and later Blu-Ray quality) movies playing on a big TV from the PS3. I want RAID 6 level redundancy so that when 2 or even 3 drives fail (as Murphy's Law says they will want to do all at once), I can still recover. (Yes, I'm an insurance dude, with all the risk aversion that this implies)
What would y'all suggest that I do here, short of getting the same energy-hogging racks in corporate server rooms? Is there a way to "go green" with a multi terabyte multiple redundancy system or am I just wishfully thinking?

I'm quite new to linux but I have configured a simple ftp server and it's working great. I have a FTP-Shared folder with upload and download subfolders. Under upload's and download's I have identical category subfolders like mp3's, movies, software etc. in both. As the guy's upload, I would like to create a line crontab where I can move all the content under /FTP-Shared/upload/mp3/* older than 14 day's to FTP-Shared/downloads/mp3/ recursively (Like in cp command), but the timestamp must be searched on the first directory and not sub files example: /mp3/Club Dance/CD1/Hallo world.mp3This is how far I got:[root@clients ~]# /usr/bin/find /FTP_Shared/upload/Mp3s/ -depth -mindepth 1 -mtime +14 -type d -exec mv -f {} /FTP_Shared/download/Mp3s/ ;This command moves the directory and files, but it is not recursively

I have a dual-boot macbook with an OS X partition and an ubuntu partition. When I first installed ubuntu, I changed my home folder to my OS X home directory to synchronize all my files from both. My home directory is now /media/sda2/Users/username/. In a regular home folder, the icons for Documents, Music, Pictures, Movies, etc. are different (not just with emblems, but actually different icons). But when I changed my home folder, these subfolders' icons stayed the same as regular folder icons and I can't figure out a way to change that default setting. I know how to change the icons for each folder manually, but these changes don't appear everywhere (i.e. nautilus, places, etc). Furthermore, every time I change my icon theme, I would have to manually reassign icons for these folders. Is there a way to globally change the folder icons for these folders?

I need to specify a different path to home directories on a particular server than what LDAP contains for the users, besides using a symlink. E.g. "/Users/jdoe" vs "/home/jdoe" I don't want to change the actual LDAP attributes, just want a particular server to point them in the right direction (Ubuntu 10.04).
I'm assuming it's something I could probably set in pam configurations?

I have a second large storage hdd mounted in Ubuntu in /media/storage. I would like my home directories for me and all future users of the system to be located on this storage drive as well.
I was thinking that the easiest way to accomplish this was to move /home to /media/storage/home and then create a symlink so that /home points to /media/storage/home. Would this work okay?
The only reason I ask, is because I know that a users home directory has a lot of special configuration information stored in it, so I didn't know if this would screw up anything on the system.
Are there any better alternative methods to relocating the home directory?

I grant read privilege to all the users to my .vimrc file . But my colleague still can't read my .vimrc file . I guess in addiction to give the read privilege to the .vimrc file, in some way I should give the person who want to read it the "access right" to my home directory first---which I don't know how to do it.

This might see a dump question but I will make it anyway .Here is the scenario:I have two users on my Linux Mint installation:
User A
User B
I want User A to be able to write on User B home directory, say /home/B.For this I have changed users's B home directory to look like this:ls -ld drwxrwxr-x 36 B music 4096 2010-09-26 10:31 /home/BI have created a "music" group and assigned to /home/B, so all users that are member of "music" are going to be able to write on User B home directory, right?The answer is No! Not here in my box Can you tell me why?Why users under group music can't write on /home/B if B directory is owned by group music and group music has write permissions?

I have tried googling many times for answers, but haven't yet found a solution to my problem (maybe its my selection of search terms).I screwed up my debian system by trying to setup an ftp server with vsftpd very quickly withouteading much documentation (very stupid) as root. I must have screwed up the something to do with the home directory for my user because now cannot even log in with my usual username and password when the computer starts up. All the computer says when I try to log in is:
Unable to cd to 'homemyusername'I can log in as root with Debian single user mode, so I am hoping I can reset my home directory so it works again. Also, I cannot seem to ever get the gnome login screen just a terminal login screen.

I installed the beta of Ubuntu 9.10 Karmic, and I am now stuck with a barely usable system, so I am going to remove it. I've already backed up the home directory, and what I was wondering is this:If I were to install a completely different distro, like, say, OpenSUSE, would I be able to copy back my home directory without problems and have things still work, or would I have to reinstall Karmic? I had always believed that Linux distros were more or less the same except for cosmetic differences, but this seems like it'd be a different case somehow..
