Solutions

type sudo and password repeatly is a terrible thing

especially you are handling lots of command-line work

there are several ways to skip typing sudo and password

choose your own way after considering security issue cautionsly

Skip Password for Sudo

open sudo config file

sudo visudo

edit sudo script

root    ALL=(ALL:ALL) NOPASSWD:ALL
%admin  ALL=(ALL) NOPASSWD:ALL
%sudo   ALL=(ALL:ALL) NOPASSWD:ALL

then you don’t need to type password after use sudo command

Directly Delete Password

sudo passwd -d easing

then you don’t need to type password any more, as there is totally no password

even if outside command line, you won’t type it anywhere

Use Sudo for All Commands

sudo -s

this command means using super user doing all things below

then you don’t need to type sudo after this, but just for current terminal window

Grant Permissions to All User

sudo chmod -R 777 /home/<username>

this can help to decrease usage of sudo in a certain degree, when visit files under home dir

do not try to chmod for system dirs, such as / /etc /root /usr , which may cause unrecoverable damage to system

as linux will check permission for key files, if fails, all things will not work
