Add sudoers edit

Instead of editing /etc/sudoers, you can add a user to sudoers by adding the user to the group 'sudo'.

For example:

# usermod -a -G sudo user

Linux add/remove an existing user to a gorup edit

Add an existing user to a group

# usermod -a -G GROUP USER

Remove an existing user form a group

# gpasswd -d USER GROUP

encfs - fuse: failed to open /dev/fuse: Permission denied edit

encfs - fuse: failed to open /dev/fuse: Permission denied

That group may not be present for the current shell session. Just do the following.

grep  /etc/groups

to see the list of groups in which the user has been added. To take effect, you may have to logout and login again. Or it would take effect after the next reboot.

chmod 660 /dev/fuse
