Ubuntu :: Permissions Of Multiple Files At Once?
Aug 6, 2010
I made some files belong to root, so that my sister couldn't read them while she was staying with me, there were about 40 files altogether but I did them all at once by change the permissions of the folder and clicking "apply Permissions to enclosed files" but now I want to change them back to belonging to my user account so Opened a gksudo nautilus windows and I went on folder properties and set the permissions to [user] and clicked apply to enclosed files, but it only did the folder. I tried selecting all the files and changing them all at once that way but it won't let me, how can I make the files belong to me again, other then one by one? I dont know how to use the CLI that much.

I am setting up a samba server to operate in a windows AD domain. I want to set permissions for multiple groups to have different levels of access to one group of files, and it looks to me like unix permissions will not do that? I always hear about how robust linux is, and it seems to me that their file permissions model is WEAK compared to microsoft's?

I often use the rpl command to make changes to multiple html files at once. For example:
rpl -R '<br />' '<br /><br />' mydirectory However, I haven't been able to figure out how to change multiple lines. For example, let's say I want to change all occurrences of :
<br />
<br />
to:
<br />
I've tried
rpl -R '<br />
<br />' '<br />' mydirectory
but that didn't work. how to do this with rpl or some other way?

I am to rename all the files within a directory (which contains multiple subdirectories) recursively without invalid characters.
I tried the coding posted above.
find . -type f -printf '%p
' | while read file; do
oldfile=$(basename "$file")
newfile=$(echo "$oldfile" | sed 's/[^A-Za-z0-9_.]/_/g')
if [ ! "$newfile" == "$oldfile" ]; then
echo mv "$file" "${file%$oldfile}$newfile"
code....
but I get an error on both of them stating "find: bad option -printf find: [-H | -L] path-list predicate-list"

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?

There is a folder that is owned by user tomcat6: drwxr-xr-x 2 tomcat6 tomcat6 69632 2011-05-06 03:43 document. I want to allow another user (ruser) write permissions on document folder. The two users (tomcat6 and ruser) does not belong to same group. I have tried using setfacl: sudo setfacl -m u:ruser:rwx document
but this gives me setfacl: document: Operation not supported error.

this directory has permissions 750 and is owned by user1 and group user1 I have an admin user that is primarily a part of group admin, but also a part of group user1 what would stop admin from having read and execute permissions on this directory? I'm running clamav and have a clamd daemon running as user admin (I could run it as any user, and I may make a special user later, but I don't want to run it as user1, user2, etc).
I have 2 (technically lots more, but let's just say 2 for now) users, user1 and user2 that have home directories /home/user1 and /home/user2. each is owned and group owned by user1:user1 and user2:user2 respectively with permissions of 750. my admin user is part of groups admin, user1, and user2 I need this to be able to scan my user's directories using the command (is this correct?):
clamdscan --move=/files/quarantine/ --config-file=/etc/clamd.d/adm.conf /home/user1/file
doing this gives the error:
/home/user1/file: lstat() failed. ERROR
If I change the directory permissions to 755, it works fine.Or if I leave the permissions 750 and change the directory group ownership to admin, it works fine. So, why would this be? Obviously it is a permissions issue, but why is it not reading admin as part of the user1 group and allowing the same permissions as it does when making the directory group-owned by admin?

I have a remote directory shared over NFS called tech with perms set as 0750 and owner set to root:tech. I have 2 groups: tech, and techAdmin. tech can read and execute within tech/. techAdmin can read, write, execute. I have 4 users: user1, user2, user3, user4. user1 and user2 is a member of techAdmin, user3 and user4 are members of tech. simple so far...but wait here's the problem. If user1 creates a file inside tech, user2 cant read or modify it because user1 owns it. Here's a few sites that reference this problem:

I have limited experience in terminal, but let me first explain what I am trying to do to see if there is some easier way to do it. Basically I want to change the skin in aMSN. I downloaded the new skin but am unable to unzip or move it without /root permissions. I don't know how to acquire this without being in terminal. So I figured there had to be some way to go into the terminal and use it to move the unzipped folder from the desktop to the aMSN skins folder.

I need to setup permissions for some files.The users on this Ubuntu system should be able to read/view the files.They cannot write/edit the files.Most importantly, they should NOT be able to copy the files anywhere. They should NOT be able to copy these files to another folder, USB device, etc.

I did a clean install of 10.04 over the weekend and copied all of my backed up files from my external drive back to my internal drive. However, I've noticed that when I moved all my files back, they're all now marked as being executable. I've since fixed this, but I was wondering why this happened to begin with?
I use rsync to backup my files (grsync to be exact), but when I do so I copy files from my internal drive, which is formatted as ext4, to my external drive, which is formatted as NTFS (I keep my external drive as NTFS in case I need to hook it up to a Windows machine). Does the file system discrepancy have to do with why my permissions change when I backup/restore my files? Is there a way to prevent this? Or should I be backing up my files a different way?

I am using Ubuntu 10.10 Meerkat and everytime I attempt to edit the permissions of a file either using the command line or gui it does not stick. When I use the gui and click in the permissions tab and then choose execute file the check mark appears and then immediately disappears.
When I attempt to change permissions via the command line and execute a script even if the script was created by me it does not work and when I check the permissions there is no changes from the original before my attempt to add execute permissions.
Even when I change permissions for read and write they don't stick.
I had no problem when I was using 10.04 and need to get this fixed.
PS. I made sure I am changing permissions using root privileges.

I wanted to know whether its possible to prevent some user from playing mp3/any other media files, using the chmod command? Are the read and execute bits meant only for text/office files?

I logged on today to find that all the folders in my home folder are empty when I look at them in nautilus. When I try to cd into them via the terminal, I get a message that says I don't have permission. When I cd as root, however, all my files are there.
Yesterday I was messing around with Apache authentication, and it appeared from Firefox that the contents of one of my directories was empty.
I checked, and I am an Administrator, etc. I'm on Ubuntu 10.04.

I've recently converted two Ubuntu 10.04 (one 64, one 32bit) machines to LibreOffice. We've used OpenOffice.org since early 2.x The issue is a database file created in OOo and now needing to be accessed in LO. As far as I know, there shouldn't be any issue with file compatibility. On the 64 bit machine, (a Ubuntu server installation - not headless) the file opens with no trouble and is fully accessible. (forms, reports, tables, etc.) However, on the 32 bit machine, trying to access the file over the network on the server via samba (because we also have Windows machines on the network, so I serve it all up via samba) I am able to open the database, but get the following error when trying to access any table, form or report: The connection to the data source "Mattress Prices" could not be
established.

I've been using Ubuntu for a few years and I am having issues trying to load .jar files and .exe files in Wine. I keep getting an error message that says my computer doesn't have permission to load these files. I've done some research and found people saying to enable the file as executable in the files properties, to enable executable in the permissions folder, and to allow source code on the Ubuntu Software screen, but whenever I try to check these boxes, they immediately revert to having a line through them instead. I remember when I was running Ubuntu a few years ago I was able to completely disable this restriction in terminal, but I can't remember what I did.

I want to make a webserver with multiple users allowed to login through SFTP to a specific folder, www.Multiple users are added, lets say user1 and user2, and all of them belonging to the www-data group. The www directory has an owner www-data and a group www-data.
I have used chmod -R 775 on the www folder, but after I try to create a folder test through my SFTP server (using Filezilla) the group of the directory created has only r and x permissions, and I am not able to log in with the second user user2 and create a directory within www/test due to a lack of w permission to the group.
I also tried using chmod 2775 on www directory, but without luck. Can somebody explain to me, how can I make it so that a newly created directory inherits the root directory group permissions?

I'm using my Linux (SLES 10) server as a File Server at this point. I need to set File Permissions to nested folders differently to different groups. For example:
homesharedengineering* should be read only for groupA
homesharedengineeringadmin should be read & write for groupB Plus read only for groupA
homesharedengineeringautocad should be read & write for groupC Plus read only for groupA
I've been using Webmin and Putty to set permissions but Putty only allows me the Default Group, it won't allow me to set several groups on the same directory. Webmin seems to allow me to add multiple groups (Webmin --> Others --> File Manager --> Info & ACL tab will provide extended abilities) but when I add multiple groups, they don't seem to take effect? I'm wondering if my setup at the 'Share' level or at the hierarchy of my folder structure (unix based) needs to be set specifically?

After burning files to DVD+RW, the owner is changed to root, and all permissions are read only. I want to periodically open these files, update them, and save to the DVD again, but I no longer have permission and cannot change the permissions since I am no longer the owner. I tried sudo commands, but get responses "Read only file system". I have erased and reformatted the DVD and started over but get the same results.
I have Ubuntu 9.04, and have tried Brasero and Nautilus and get the same problem. Am I using the wrong kind of DVD/CD?

Also with the command;
Code:
chown -R root:root files
what is the -R for and when do I need or not need it?

I've been using Ubuntu for about 2 years now, but still have trouble with some of the finer workings of linux. I have a laptop that I use for general computing, and a desktop hooked up to a TV as sort of a remote backup/htpc. A problem I run into is when I transfer files, they get transfered with the owner set as the original computer's account, and I can't do anything until I open a remote viewer and gksudo nautilus to change the permissions of the file. I looked at articles about permissions and uid's, gid's, and umask but can't figure out how to apply it to my situation.
I thought about doing something with groups but am not sure exactly what, and anyway, default group settings only give read access and what I'm really looking for is the ability to manipulate files and folders across the entire /home dir on my desktop from my laptop. Desktop is running 8.04 and laptop is running 9.10. BTW I am currently sharing through smbfs. I read that this has been replaced by cifs, but at the moment I would prefer not the mess with things if I don't need to.

I got two ubutnu servers running side by side, I need to transfer several dir's of files, incl sub dirs to the other server via ftp and retaining the file permissions and dir structure. Both servers have ftp access, I am assuming theres an ftp command I use on the destination server to connect to the source server and retrieve the files? All the files reside in the one dir and need to be copied to the same dir on the destination server.

I'm sure that the issue I'm having is easily solvable once I gain some understanding about copying files - and file permissions in Ubuntu. Here's my situation:
I have an external HDD where I like to back up some files (I mess around with distros on my main machine and feel less stressed knowing the important stuff is backed up). I have an ext4 partition on the external drive where I have copied files, both through the terminal (cp 'filename' /dev/sdc3) and by drag and drop (gnome-terminal).
The problem is, once the files are copied, most are inaccessible. I can view them, but some directories and individual files say I do not have permission to open them. Others are accessible. This is from the same user profile that copied them.
How do I see what's going on? More importantly, how do I make files on external drives available to any user or OS (that can handle ext4)? I want to make sure that if my whole system gets effed that I could still do a reinstall of my OS and then access those backup files.
