I have a shared partition on Ubuntu, 'dm-6', if I create a new folder in it, it has 'teocomi' as owner.If I create the folder from another (windows) PC the owner is 'nobody' and from Ubuntu I have to chmod/chown it in oredr to edit its content...Is there a way to set automatically permission and owner for newly created folders and directories?
I tryed with:
Code:
sudo chmod u+s -R /media/dm-6

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!).

Currently I am doing a java project and I renamed some file/folders to start with '.'. i.e. ".project", ".classpath", ".settings/"
I can see them on my desktop but i cannot delete them. In the terminal, "ls" command does not show these files exist. "rm" will also say cannot find these files. How do I get rid of these files/folders?

Ok here is the deal, I am allowing my neighbor access to some networked folders on my ubuntu file server in exchange for access to their washer & dryer. I have already created mapped drives on their xp machines but now I want to only allow them "read only" access so they don't accidentally delete anything?

I have a 500GB iomega portable HD. I used Gparted to split the drive into two partitions, a fat32 of roughly 400GB and an EXT4 partition of roughly 100GB.
On my EXT4 partition, there is a folder called lost+found. I can't delete it because I need to be root, yet my account has administrator priviliges (but I CAN rename the folder). I can't create other folders on this partition, nor can I copy-paste and files on there either.
Basically, that partition is unuseable. In the properties of the folder, it says that I am not the owner so I cannot change the permissions. (It is definitely MY hard drive)
All options are greyed out.
How do I give myself permission to use this EXT4 partition?

I have installed a new system on my desktop computer, and would now like to delete files/folders from the web interface, as they no longer reflect the files and folders on my desktop PC. I use my desktop PC to sync files and folders one way to my laptops.

I've just read that I can't change the file permissions of files and folders if they are sitting in what was my old Windows D: drive. Is this correct? If so what is the work-around?
I don't want to have to cut and paste that entire D: drive's contents over to a recognised Ubuntu folder. I had in my mind that this D drive would continue to be my data dumping ground, to which I need read/write access to.

We have a development server not accessible to the public used for testing which was setup for us. When attempting to have my PHP scripts upload an image to a folder, I have to CHMOD the folder to 777. Ideally, when a folder is created it has permissions set to 755 - I want to be able to upload to them. Is there a way to change permissions to allow the PHP scripts that run to be able to write to a folder? I know it has something to do with owner or group, but I don't know where to start.

I just had a bad experience with a server, and now i have a 17GB lost+found. It appears a lot of the stuff in there are folders which are empty. Since those really serve no purpose as far as recovering data from what I can tell, is there a slick way to delete just the empty folders from my /data/lost+found folder, leaving me with just the stuff I truly need to look through?

I have a USB drive that has a TON of folders on its root level. I want to remove all those folders and their contents except three of them. I know if I do rm -rf that will kill everything, is there a way to exclude three folders, say folder1 folder2 newfolder, and do it all in one statement?

I've a problem on one of my servers with file permissions. Quite simply , when I run chmod 777 -R against a folder , it seems to be inconsistent on making that particular folders permissions trickle down to the folders beneath. Some folders inherit its permissions , some don't. For example...
/projects
Contains
/Jan /Feb /Mar /April
They all in turn contain folders marked /1 , /2 , /3 , up to /10, these folders all contain more folders , running to a depth of 6.
However , depending on what folder our users save their files into , some are saved with rwxrwxr-- , some get saved with rwxrwxrx. Forgive my lack of understanding but if I run the above command against the top level folder will this not make every folder and file below it inherit its permissions of 777 ?? Or is there something else that I need to do?

I have a Samba share set up on a SUSE server that about 30 Windows XP clients are connecting to on a daily basis. They connect using Winbind and their Active Directory usernames and passwords which are stored on a Windows small business server (Server 2003). The share is called "company" and it's right off the root of the partition. Within "company" there are about 75-100 folders, most of which need to be publicly available and publicly writeable. There are a few that need to be locked down to a certain group of people so I've used group membership and access control lists for those.
The permissions on new files/folders still aren't right though, so I'll just try to explain what I WANT rather than trying to resolve what is HAPPENING since I think that'll be easier. Currently the entire company directory and all subdirectories and files are user-owned by "administrator" (an active directory domain admin). I'd like new folders and files created anywhere in that directory or any subdirectory to maintain that ownership by administrator, regardless of who creates them.
Likewise, the entire directory and all subdirectories/files are group-owned by "domain users" (a builtin active directory group which is pulled in via winbind) which gives everyone write access to everything. I'd like that ownership to be maintained as well on any new files or folders created in /company or any subdirectory therein. I think this is working for the most part as I've set the setgid bit on company. I'd like any files or folders created in /company or any subdirectory therein to have 770 permissions (rwxrwx---).
So, what I want is regardless of who creates a file or folder anywhere in "company" - it should be owned by user "administrator" and group "domain users" and have 770 permissions. I'd like to make a little tweak to this post. Above I said I wanted anything created under Company to be created with group owner "domain users" - that actually only goes for anything that will be public. On the folders I have locked down via group membership and ACLs the new files/folders created within should maintain ownership of whatever group owns that directory. I should be able to do this by setting rwxrws--- permissions on secured directories.

I recently moved to a new machine, and I copied my entire home folder across. This included lots of hidden (starting with '.') folders, and in many cases they are config folders for packages which I have not installed on the new machine. They are taking up space, so I would like to delete them, but to go through manually and figure out which ones I need would be very laborious. Is there a way to find, and perhaps delete, config folders for packages that are not installed?

I had a major raid event recently which caused my Ubuntu 9.04 server to recover part of its file journal on the system partition. This caused some of the file permissions to go all funny and I now need to change them manually.
What the file permissions should for the following folders:
/etc/
/home/
/lost+found/
/mnt/
/root/
/sbin/
/srv/
/tmp/
The server is running and I fixed the some of the ownership issues already. I use a basic LAMP setup with samba, and proftp.

First off I want to apologize for the fact that the first several paragraphs go into something seemingly unrelated to the subject of this thread. However I want to be sure that those who choose to lend me a hand understand where I'm coming from and why I'm asking that question.I just recently switched from Windows Vista to Ubuntu 10.04. So far I've been loving it mostly. But their is one oddball thing I haven't been able to get working. That is a pair of shared folders located on my NTFS external drive connected via USB2.
The drive was automatically mounted on first boot and has full read/write access for owner (which is my username) right out of the gate. For this reason I assumed I would be good to do this.I've been unable to get it working in Ubuntu. As it stands now I've manually added them to smb.conf, added them to the Samba Server Configuration and finally by right clicking the folder in nautilus and choosing Sharing Options. All with varying resultsAt best it will show the shares under the computer but not allow access. I've also cleared out all of these for those folders to try them individually or in different orders. What I found was that using Sharing Options first gives this error and sets nothing up. But either of the other two will at least show the share albeit with no access.
Quote:'net usershare' returned error 255: net usershare add: cannot convert name "Everyone" to a SID. Invalid parameter.What I've discovered is that if I use just the Sharing Options from Nautilus on any folder located on my ext4 partition or the internal NTFS partition then it will ask if applicable to adjust the permissions and though nothing appears in smb.conf that it works more or less just fine.Having played with "ls -l" I discovered that by default that ownership of the folders on the external NTFS is set to myself and that permissions are 700. On the ext4 partition ownership is set to myself and permissions on folders 711. The folders on the internal NTFS partition has an ownership of "root" and permissions set to 777
From here I tried to use "sudo chmod" via a terminal to manually change permissions for folders on all 3 partitions and I can do so for the ext4 and the internal NTFS owned by root. But no matter what I cannot for the external NTFS.The main thing is I want to know why I can't adjust those permissions on the external. I'm convinced that something to do with the way USB drives work by default must be impacting this but I could not find a single thing anywhere to confirm this much less to offer a solution.The second thing is that I installed and used mountmanager to automatically mount the internal NTFS and according to that softwares options the setup for both it and the external NTFS are the same. But if that is true then why is the external owned by me and the internal by root and the resulting permissions are completely different?

I'm on Ubuntu 10.10. I installed Samba and went Administration > Samba. Added a folder [Videos] to share (this folder is on an ext partition). I then went to the folder [Videos] Right+Click > Sharing Options. I selected 'Share this folder', I put in a name and comment, checked Allow others to create and delete files in this folder and checked Guest Access.
When I view this shared folder [Videos] from my Windows PC I can access it with no problems but when I try drill down into sub folders I get a permissions error. [Attached a screenshot of the error]. If I share each folder separately then I can access them but obviously I'd like to share a folder and all it's contents.

I have an FTP server on my network (currently ran on IIS). When I connect with Nautilus to FTP and try to delete folder (files delete works) I get error.I tried Filezilla and Gnome-Commander as clients - they cat delete directories just fine. I tried to solve this problem for months because I like the convenience of having my FTP bookmarked in Nautilus and use it from there.Today I finally found a reason for Nautilus not being able deletedirectories, but I can't find a solution to that. I've checked FTP logs and saw that all working ftp-clients are performing RMD on directory name only, while Nautilus always prepends directory name by / symbol. So, let's say I'm trying to delete folder call "Test"Filezilla and Gnome-Commander are logged as doing RMD on "Test", but Nautilus was logged as doing RMD on "/Test" and server replied that "/Test" folder doesn't exist
