How to create a new normal user with sudo permission

How to create a new normal user with sudo permission?

This procedure can be used in any Linux distro to add a normal user. That includes ubuntu, Linux mint, or even Centos

useradd -m username

# -m creates a home directory for the user.
# for more config option while adding user read
man useradd
## :)
Set password using passwd in order to login

passwd username

Add user to sudores so that we can use “sudo” to do administrative actions.

usermod -a -G sudo username

The option -a means to add and ‘-G sudo’ means to add the user to the sudo group. If you want to know more about the usermod command, issue man usermod command to know more about usermod

How to fix a locale setting warning from Perl?

When I run perl, I get the warning:

When I run apt, I get the warning:

When I run aptitude, I get the warning:

perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:
    LANGUAGE = (unset),
    LC_ALL = (unset),
    LANG = "en_US.UTF-8"
are supported and installed on your system.
perl: warning: Falling back to the standard locale ("C").

instead of installing the locale, You can also change the locale. On my Ubuntu box, this is done for one user by editing ~/.pam_environmentChange the variables were es_US.UTF-8 or similar to en_US.UTF-8. or similar requested – Janus Troelsen Jun 8 '14 at 12:34 & f1vefour Feb 18 '15 at 13:12

Use:

export LANGUAGE=en_US.UTF-8
export LC_ALL=en_US.UTF-8
export LANG=en_US.UTF-8
export LC_TYPE=en_US.UTF-8

It works for Debian. I don't know why - but locale-gen had not results.

(add) On Debian, local-gen only processes locales that are uncommented in /etc/local.gen. You may need to do echo en_US UTF-8 >> /etc/locale.gen first. – akhmed Nov 24 '15 at 2:45

Important! It's a temporary solution. It has to be run for each session.

#pseudoPermament I just put it into my .bashrc file. – Anirudh Ramanathan Jun 8 '14 at 16:08
