I'm new to Ubuntu and need to create a new folder in /var and need all users on the machine to have full permissions to this folder.

How should I proceed?

  • Welcome to Ask Ubuntu! ;-) Do you want to create a folder in /var that has full permission for all users??? There is already one! and it's called tmp!

    /tmp is a system directory with a temporary filesystem which uses RAM memory. Anything put there will be deleted upon reboot. Jan 11, 2016 at 23:05
  • @EduardoCola: it actually uses disk, but yes, it's deleted upon reboot! (You can see this happening when you remove quiet splash from the boot parameters...) ;-)

  • Isn't /tmp used with tmpfs? Which uses RAM? Jan 11, 2016 at 23:43

Press Ctrl+Alt+T to go to a terminal and type:

sudo mkdir /var/szDirectoryName
sudo chmod a+rwx /var/szDirectoryName

Where szDirectoryName is the name of the directory you would like, a means "all" (users) + means "add the following rights" and rwx means read, write and execute respectively...

Note: there already is such a directory in /var which all users have access to: tmp (full path: /var/tmp) which itself is symlinked to /tmp.
Beware however that all files in /tmp are deleted at boot time.

For any further information, here is a great resource on all directories in Linux.

Open Terminal

Create Directory with mkdir:

sudo mkdir /var/DirectoryName

To give all permissions to a folder give chmod -R 777:

sudo chmod -R 777 /var/DirectoryName

    This works for me, since I also need to give all the sub folders the permissions. Jul 14, 2020 at 3:06
  • Do we need to type full path here? Feb 19, 2021 at 7:43
  • yes. we need to move to the path or we need to type the full path for the folder Feb 23, 2021 at 5:56

Below gives all permissions to everybody to all files and subdirectories:

chmod -R a+rwx path
  • Is this true for any new files/directories made or only for existing files and directories? Oct 9, 2022 at 19:39

To give all permissions to all the users, use the following command:

chmod -R a+rwx /path/....

Note: It's Usually not recommended to give every user every permission of a directory, be careful while using this command.

To give permissions to a specific user:

sudo chown -R username:grouname /folder_path
