Question

我是实验室计算机的用户之一。我希望 PATH 成为：

PATH=/home/gsamaras/mpich-install/bin:/usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games

而不是：

PATH=/usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games

出于这个原因，我修改了 .profile ：

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

然后我做了source .profile并且没关系。但是，第二天（当我打开电脑时）并最终登录到我的帐户时， PATH 被重置。然后我找到/etc/profile，这似乎是我的关键文件，因为它有这个：

if [ "`id -u`" -eq 0 ]; then
  PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin"
else
  PATH="/usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games"
fi
export PATH

但是，我认为这将在本机器中的每个用户执行，而不仅仅是我，所以我应该如何修改它以便我不需要获取本地.profile每次我登录？

PS - 我知道sudo的密码。

我找不到任何 .bash_profile 文件：

gsamaras@pythagoras:~$ find .bash_profile
find: `.bash_profile': No such file or directory
gsamaras@pythagoras:~$ find /etc/bash_profile
find: `/etc/bash_profile': No such file or directory

这是我的 .bashrc 文件：

Answer 1

来自debian wiki：

将所有全局定义（即影响所有用户的定义）放入/ etc / profile。
将所有个人定义插入〜/ .profile
创建或编辑文件〜/ .bash_profile并包含命令：
```
if [ -f ~/.profile ]; then
     . ~/.profile
fi
```

Answer 2

在.bashrc文件中添加以下命令：

PATH="/home/gsamaras/mpich-install/bin:$PATH"

然后执行：

. .bashrc

从您的主目录。现在，检查路径（或）注销并登录。

登录时PATH未更新
