问题11.04. 。
原标题:Question about .profile generated by ubuntu 11.04

我在<代码>~/.profile的底线上注意到以下线。 a 系由我安装的乌班图11.04产生的。

# set PATH so it includes user s private bin if it exists
if [ -d "$HOME/bin" ] ; then
    PATH="$HOME/bin:$PATH"
fi

I see the logic there, but shouldn t the PATH variable be exported?

# set PATH so it includes user s private bin if it exists
if [ -d "$HOME/bin" ] ; then
    export PATH="$HOME/bin:$PATH"
fi

如果没有,那么我就不理解,一旦达到<代码>底线后,伙伴关系的价值不会消失。 ~/.profile,我看不出(至少是明确)在系统的任何其他单页上出现。

最佳回答

如果一个变量已经出口,你不必再出口。 是的,壳体(道德上等同)源代码<>。 当你开始计票时(除非还有<条码>.bash_profile;但应习惯地提出<条码>。
