linux下改变语言环境变量

linux下改变语言环境变量

学习时环境变量是中文，不能更好的学习linux需要改变成英文。

 

查看当前语言环境

echo $LANG

 

 

在命令行下直接输入LANG=en_US

 

 

显示为英文，此命令即时生效，但不能永久生效。

 

需要修改/etc/sysconfig/i18n 配置文件。

永久生效，但不即时生效。

 

系统版本 centos6.0

==================================================================================

将Ubuntu系统语言环境改为英文的en_US.UTF-8

查看当前系统语言环境

locale

编辑配置文件，将zh_US.UTF-8改为en_US.UTF-8，zh改为en

sudo nano /etc/default/locale

LANG="en_US.UTF-8"
LANGUAGE="en_US:en"

继续查看更改后的系统语言变量，如果出现下列错误，说明没安装en_US的local

www.linuxidc.com @ubuntu:~$ locale
locale: Cannot set LC_CTYPE to default locale: No such file or directory
locale: Cannot set LC_MESSAGES to default locale: No such file or directory
locale: Cannot set LC_ALL to default locale: No such file or directory
LANG=en_US.UTF-8
LANGUAGE=en_US:en
LC_CTYPE="en_US.UTF-8"
LC_NUMERIC="en_US.UTF-8"
LC_TIME="en_US.UTF-8"
LC_COLLATE="en_US.UTF-8"
LC_MONETARY="en_US.UTF-8"
LC_MESSAGES="en_US.UTF-8"
LC_PAPER="en_US.UTF-8"
LC_NAME="en_US.UTF-8"
LC_ADDRESS="en_US.UTF-8"
LC_TELEPHONE="en_US.UTF-8"
LC_MEASUREMENT="en_US.UTF-8"
LC_IDENTIFICATION="en_US.UTF-8"
LC_ALL=

查看系统内安装的locale

www.linuxidc.com @ubuntu:~$ locale -a
locale: Cannot set LC_CTYPE to default locale: No such file or directory
locale: Cannot set LC_MESSAGES to default locale: No such file or directory
locale: Cannot set LC_COLLATE to default locale: No such file or directory
C
POSIX
zh_CN.utf8
zh_SG.utf8

看吧，没装en_US.UTF-8 安装en_US.UTF-8

www.linuxidc.com @ubuntu:~$ cd /usr/share/locales
www.linuxidc.com @ubuntu:/usr/share/locales$ ls
install-language-pack  remove-language-pack
www.linuxidc.com @ubuntu:/usr/share/locales$ sudo ./install-language-pack en_US
Generating locales...
  en_US.UTF-8... done
Generation complete.
dpkg-trigger: dpkg-trigger must be called from a maintainer script (or with a --by-package option)

查看，应该一切正常了。

www.linuxidc.com @ubuntu:/usr/share/locales$ locale
LANG=en_US.UTF-8
LANGUAGE=en_US:en
LC_CTYPE="en_US.UTF-8"
LC_NUMERIC="en_US.UTF-8"
LC_TIME="en_US.UTF-8"
LC_COLLATE="en_US.UTF-8"
LC_MONETARY="en_US.UTF-8"
LC_MESSAGES="en_US.UTF-8"
LC_PAPER="en_US.UTF-8"
LC_NAME="en_US.UTF-8"
LC_ADDRESS="en_US.UTF-8"
LC_TELEPHONE="en_US.UTF-8"
LC_MEASUREMENT="en_US.UTF-8"
LC_IDENTIFICATION="en_US.UTF-8"
LC_ALL=

注释：locale 命令是将有关当前语言环境或全部公共语言环境的信息写到标准输出上。
