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! – Fabby Jan 11 '16 at 22:49
  • Thanks for replying , yes that i want to do but please what do you mean by There is already one! and it's called tmp! – sam Jan 11 '16 at 22:54

    /tmp is a system directory with a temporary filesystem which uses RAM memory. Anything put there will be deleted upon reboot. – Eduardo Cola Jan 11 '16 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...) ;-) – Fabby Jan 11 '16 at 23:12
  • Isn't /tmp used with tmpfs? Which uses RAM? – Eduardo Cola Jan 11 '16 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.

  • but what is that mean after i executed your command i got total 0 when i wrote ls -l /var/nameoffolder? – sam Jan 11 '16 at 23:04
  • i know that command ls .. used for listing what is in that folder but -l give me the permissions rigth ? – sam Jan 11 '16 at 23:08
  • sorry , you edited your answer with statement i want to ask about there is already a directory in /var that all users have access to: tmp which is symlinked to /tmp this means that folders that i will created in /var will be deleted liken in /tmp – sam Jan 11 '16 at 23:21

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. – Jonjie Jul 14 '20 at 3:06

    sudo chmod -R 777 / now my life is less stressful, thanks – Bersan Dec 7 '20 at 22:53
  • Do we need to type full path here? – Goran_Ilic_Ilke Feb 19 at 7:43
  • yes. we need to move to the path or we need to type the full path for the folder – Pradeep Kumar Prabaharan Feb 23 at 5:56
