[Solved] CentOS / Debian / Ubuntu changes the system language via command line (shell script)

Introduction

When we write Linux shell scripts, we usually encounter things that need to modify the system default language.

CentOS will be simple, but Debian and Ubuntu will have a lot of trouble. Today, I will tell you how to modify the Linux system language only through the command line.

I will demonstrate modifying the system language to Chinese. (You need to modify the text for your language)

Let’s start

CentOS / Redhat

1. Install locale

yum groupinstall "Chinese support" -y
yum groups mark install "Chinese support" -y

2. Set the system default language

localectl set-locale LANG=zh_CN.UTF8

Debian / Ubuntu

1. Install locale

apt-get install locales -y

2. Modify the file via the command line (cancel the “# symbol” before your language)

echo '# This file lists locales that you wish to have built. You can find a list
# of valid supported locales at /usr/share/i18n/SUPPORTED, and you can add
# user defined locales to /usr/local/share/i18n/SUPPORTED. If you change
# this file, you need to rerun locale-gen.

3. Set the system default language

locale-gen
update-locale "LANG=zh_CN.UTF-8"
locale-gen --purge "zh_CN.UTF-8"
dpkg-reconfigure --frontend noninteractive locales
localectl set-locale LANG=zh_CN.UTF-8

You have successfully set up your Linux system language

Please restart the Linux system.
