I would like to know how to change permissions for all my files. I don't understand why some come with ''read'' only... I'm the only one that uses the PC, so the max permissions would be good!

I ran the command chmod go+r *

But just made everything readable only...

Help guys? I want to read, write and execute all my files.

You have read write access to all files in your home directory.

To access system files use sudo/gksu (gksu is for graphical applications such as your file browser and editor).

See:

https://help.ubuntu.com/community/RootSudo

https://help.ubuntu.com/community/FilePermissions

Changing the permission of files outside your home directory will almost certainly break your system.

  • I only need Home, Media and Host folders to be read, write and execute man! But thanks :) – Tiago Rocha Mar 07 '13 at 18:51
  • I doubt you need executable permissions on those files. Read the file permissions link I gave you. for shared directories, IMO, it is best to use acl. See http://askubuntu.com/questions/52584/shared-folders-for-all-users – Panther Mar 07 '13 at 19:01
  • maybe not executeble, but definitely read and write... – Tiago Rocha Mar 07 '13 at 19:14
  • From your question(s) it seems you are new to Linux / Ubuntu. Please take a look at the links I gave you and come back with specific questions(s). The general syntax is going to be chown -R owner:group /Media and / or chmod -R 555 /Media/* and / or using acl. – Panther Mar 07 '13 at 19:17
  • yes, Im new... and I tried that, the problem is that everything is denied... I need to be the owner of my system, and I have no ideia how... that's why I asked about permissions. thanks – Tiago Rocha Mar 07 '13 at 19:20
  • ok, run this as gksu/sudo (I am talking about chown) :D –  Mar 07 '13 at 19:21
  • Use sudo chown ... , see the rootsudo link I gave you. – Panther Mar 07 '13 at 19:24
  • I'm with ubunto for 5 hours... I don't know how to work with it, or understand... Everything started with getting permissions to open a pen drive, and I ended the day lossing all the permissions! lol – Tiago Rocha Mar 07 '13 at 19:34
  • yes, it takes a while to learn a new OS, and permissions and sudo are common first steps. Permissions on a pen drive are different. I highly suggest you do some reading and ask specific questions as you have gone from asking about all files, to only some files, to pen drives all in the comments here. – Panther Mar 07 '13 at 19:36
  • I run the code like: sudo chmod a+rwx /path/to/file, and it says the file is readble only. But that I already know... It's like nothing happens... – Tiago Rocha Mar 07 '13 at 19:42
  • It must be a FAT or NTFS file system, they don't support permissions. Well you can use permission on NTFS http://askubuntu.com/questions/88080/how-to-change-permissions-to-the-other-drives-in-a-hard-disk – Panther Mar 07 '13 at 19:45
  • no man, I'm talking about files I have on my computer. Music, dosc, etc – Tiago Rocha Mar 07 '13 at 19:46
  • ask a new question, post the commands, and output of ls -lA /Media – Panther Mar 07 '13 at 19:47
  • I got this:

    gorgasm@ubuntu:~$ ls -lA /media total 2 drwxr-x--- 2 root root 1024 Mar 6 22:51 apt drwxr-x---+ 2 root root 1024 Mar 7 16:59 gorgasm

    bodhi.zazen you are right, the permission don't work because of my hdd... It's a FAT or NTFS! I need a EXT2 or EXT3. No wonder the system was getting really slower... damn! and now that I was starting to enjoy the comand line. Oh well, thank you all of the help! – Tiago Rocha Mar 07 '13 at 20:25
