Ubuntu安装完成，terminal无法启动，日期乱码
编码问题。
首先执行CTRL+ALT+F3进入[命令行界面]
/etc/default/locale 原来内容为:
代码如下:
LANG="zh_CN.UTF-8"
LANGUAGE="zh_CN:zh"
LC_NUMERIC="zh_CN"
LC_TIME="zh_CN"
LC_MONETARY="zh_CN"
LC_PAPER="zh_CN"
LC_NAME="zh_CN"
LC_ADDRESS="zh_CN"
LC_TELEPHONE="zh_CN"
LC_MEASUREMENT="zh_CN"
LC_IDENTIFICATION="zh_CN"
改为:
LANG="zh_CN.UTF-8"
LANGUAGE="zh_CN:zh"
重新登录后生效,执行ll和date可见,不再出现乱码,执行locale可见当前的语言环境.
如果你要使用英文环境,在~/.bashrc末尾加入以下内容,重新登录即可切换语言:
代码如下:
LANG="en_US.UTF-8"
LANGUAGE="en_US:en"
