How does Linux view the character set

Today, I will talk to you about how to check the character set of Linux. Many people may not know much about it. In order to make you understand better, the editor has summarized the following contents for you. I hope you can get something from this article.

1. Viewing the character set is reflected in the form of an environment variable in the system. There are several ways to view the character set used by the current terminal:

1. [root@ ~] # echo $LANG en_US.UTF-8 2, [root@ ~] # env | grep LANG LANG=en_US.UTF-8 3, [root@david ~] # export | grep LANG declare-x LANG= "en_US.UTF-8" 4, [root@ ~] # locale-a / / View the local character set [root@ ~] # locale-m / / View all supported character sets II. The difference between the three commands env and export set displays the variables of the current shell Include variables for the current user

Env displays variables for the current user

Export displays shell variables that are currently exported as user variables

Set is used to display local variables

Env is used to display environment variables

Export is used to display and set environment variables

For example, set user LANG

View LANG env | grep LANG

Set up LANG export.GBK
