If you want to delete a file that has read-but permissions in Linux, you have a few options. If the file belongs to you, you can either change the file's permissions or use the sudo command to delete the file as root. Only if you lot're trying to delete a file that has write permissions and still tin't delete it (or you see a "Read Just File System" mistake), y'all may need to remount the drive with proper permissions. We'll prove y'all how to remove any read-only file on any Linux distribution, including Ubuntu and Linux Mint.

   Open a terminal window. If a file you own is read-only, you won't be able to delete it unless you lot give yourself write permission for that file. If yous're using a window manager, press Ctrl + Alt + T to open a terminal window now.

   • Use this method if you're trying to delete a file that belongs to you but (e.g., you're the owner or in a group that has admission to read the file) but don't have permission to delete it.
   • If you lot're signed in remotely and already at a control prompt, merely skip to the next footstep.

   • The beginning three characters in the permissions (in this example, r--), are the file possessor'due south permissions. So, in this example, the owner of the file only has read permissions, which means they tin't write to, execute, or delete the file.
   • The second three characters are group permissions. If you're a member of a group and that group has write permissions to the file, yous'll be able to delete information technology even if yous're not the owner.
   • The third three characters are world permissions, which is everyone else.

5. 5

   Utilise chmod -v u+rw filename to give yourself read and write permissions. You can omit the r if you already have read permissions. Once y'all have write permissions, y'all'll be able to delete the file.

   • If you're not the file owner simply accept root admission to the organisation, you can use sudo chmod -v u+rw filename to give yourself the right permissions.
   • To see the file'due south new permissions, run ls -al again.
