tty中默认只能显示一个字节

添加以下内容到用户变量~/bashrc或~/bash_profile中,如果你希望对所有用户都生效,也可以添加到/etc/profile中

通常情况下,linux系统前六个tty是纯命令行界面

if [ "$(tty)" = "/dev/tty1" ]; then
	export LC_ALL="en_US.UTF-8"
	export LANGUAGE="en_US.UTF-8"
	export LANG="en_US.UTF-8"
fi
# 当然也可以把六个都变成英文输出
if [ "$(tty)" = "/dev/tty2" ]; then
	export LC_ALL="en_US.UTF-8"
	export LANGUAGE="en_US.UTF-8"
	export LANG="en_US.UTF-8"
fi
if [ "$(tty)" = "/dev/tty3" ]; then
	export LC_ALL="en_US.UTF-8"
	export LANGUAGE="en_US.UTF-8"
	export LANG="en_US.UTF-8"
fi
if [ "$(tty)" = "/dev/tty4" ]; then
	export LC_ALL="en_US.UTF-8"
	export LANGUAGE="en_US.UTF-8"
	export LANG="en_US.UTF-8"
fi
if [ "$(tty)" = "/dev/tty5" ]; then
	export LC_ALL="en_US.UTF-8"
	export LANGUAGE="en_US.UTF-8"
	export LANG="en_US.UTF-8"
fi
if [ "$(tty)" = "/dev/tty6" ]; then
	export LC_ALL="en_US.UTF-8"
	export LANGUAGE="en_US.UTF-8"
	export LANG="en_US.UTF-8"
fi
