General :: Use Chmod To Change The File Permission?
Apr 24, 2011If I am not the file' owner or root, can I use chmod to change the file permission?
Assume I have group/write access to the file, e.g. 775

that works to disallow non-owners from renaming the file, but what I wouldlike to do is disallow EVERYONE ( including the owner of the file ) fromediting, moving, or changing the filename once it is created. the only personwho should be able to make those changes is a special user.

They are all mounted when system is booted with Ubuntu and all files are accessible. However, when I try to change permission or limit access to a group, CHMOD command does not work. It doesn't return any error and everything seems to work fine but I can't change any permission.

I have a c file, and I want to open it but not in the terminal. After changing the permission, I tried: vi, pico, ed and vim. But, all open it in the terminal. How can I change the permission of that file to be opened and edited not in the terminal? When I change the permission from the terminal, it only let me edit it through the terminal, and when I check the permission of the file I see it as was it (no change). I need a permanent permission. Although, I command as a root.

After working through the hardwares' recovery procedure a number of times, the state of the device appears to get worse and worse. So I have attempted to rescue the files by using a program called Putty to access the device over SSH.When I access the device using Putty I login as admin. The folders I need to recover are located in the home folder. Listing the contents of the directory I get...

I'm on OS X and mount a network share from my Windows XP machine. Files by default have the rwx (700) permissions. What OS X option I need to change, that the files will have rw (600) permission?
Maybe this question also applies for Linux mounting a Windows network share.

I work in a shared computing environment and the default setting is r-x for group and others; it's upto the users to change this. I can chmod and change the permissions for all the files. However any new files created all have the default permissions. Is there anyway to change that so that I don't have to chmod everytime or run chmod as a cronjob?
View 1 Replies View RelatedI have setup my debian 8 web server.
For some reason I am having some issues with permissions of some images. They don't render because they are not set to 644. Now for some reason when I uploaded these files onto my shared hosting with cPanel the files work fine and permissions are fine. I can see there is a permission issue for the files locally on my Mac (OS X - El Capitan).
When I changes these locally on Mac the permissions go all weird and are prefixed with Custom, rather than mac-user-name: Read & Write, staff: Read, everyone: no access. then changes to custom: read & write etc. So then i tried changing permissions on web server see below and I get permission denied and after all the files are gone, i can't delete the images folder through SFTP or SSH. I changed back the image to 755 and tried deleting and still nothing. Not sure what the problem is. Before I chmod I checked that the images are set to the correct user and group as per the rest of the site.
So I try:
Code: Select alluser_name@debian:/var/www/html/_files$ chmod -R 644 images
and I get this return:
Code: Select allchmod: cannot access ‘images/box-icon.svg’: Permission denied
chmod: cannot access ‘images/ie-icon.svg’: Permission denied
chmod: cannot access ‘images/google-plus-icon.svg’: Permission denied
chmod: cannot access ‘images/mobile-ready-icon.svg’: Permission denied

I have a Qnap 219p NAS to which I have connected a USB external harddrive. I can access the external harddrive from my windows box using the network share, but at first i couldn't access the folders. The permissions set in the NAS GUI for the external drive is correct and are identical to the permissions set to the 2 internal drives.
I ssh'ed to the nas and used 'chmod -R 770 /share/external/sds1' - this granted me access to the folders, and some files. I can open all files in the root, but if I go just 2 folders 'deeper', i can't open the files in this folder, and in the folders after that.
In ssh, if i navigate to the folder wher I cannot open the files and use 'ls -l', i can see that the permissions (770) hasn't been applied to these files. How can I get chmod to apply the 770 permission to all files, folders, subfolders and files in subfolders etc., without having to chmod every folder one by one?
I have stipped down the test to the basics and still can't get it to work.I have a file called test.php stored in /usr/share/data/audio (an aliased directory in apache). This file simply contains the code...

View 4 Replies View RelatedI've got some trouble while trying to install some applications on my linux system. It is said that the files in my /var/www/html/xxx directory, where I put them, is not writeable. The command chmod 777 xxx has been tried to make it work, but the error remains when I opened the applications again.
To be specific, I want to install phpFreeChat on my system, so I put those files in the /var/www/html/freechat directory, cd there and typed chmod 777 data/private, chmod 777 data/public on bash. Here's the result of list -al data:
drwxr-xr-x. 4 root root 4096 Jun 17 15:07 .

drwxrwxrwx. 3 root root 4096 Jun 17 15:07 public
These all seemed all right to me, until I typed http://localhost/freechat in my browser. Here's the result:
phpFreeChat cannot be initialized,
please correct these errors:

View 4 Replies View RelatedI've hit a wall here; I'm attempting to find some way by which to view files and cd into directories on a device mounted read-only. So I need the permissions to read, write, execute (and the same with directories), but chmodding is out of the question because I don't want to alter the drive one iota.
I guess what I could do--what I was thinking of initially--was to dupe the whole drive and then mess with permissions. This wouldn't affect the original (actually I'm working on a duplicate of the original, but I'm treating it as if it were the original) but I was hoping for something that would maintain data integrity. This is a forensic application and not altering the data is very important.
I am trying to change the owner permission of file as "read only" when the file is rcp remote copy ) from server to another for security reason. Any way to change to permission as readonly access for owner and group ( 550 )when transfer the file using the rcp command ? I tested but still retain the original permission as source file.

Command : #rcp(local file)(/destinationserver/

Did I place image in wrong directory or is it permissions problem.

I got myself curious on the possibility to change user's permission to any command, or at least giving other users some command line "power".
It all started a few days ago, when another user here, had a problem so that the computer wasn't answering.
So, after waiting a while, chose to hit the Reset button and start the computer again.
Considering this situation, I thought myself that it would have been better to restart the computer, through command line, on any terminal (F1-F6). Anyway, this user is no administrator, thus wouldn't have permission to use the code...
So, is it possible to let other users to use such commands, in order to safe rebooting the system, without logging as root?
