Remove path from environment variables
提问by Ramy Al Zuhouri
For mistake I have added a path that I don't want to use.
I have create a file named .base_profile, exported the path using the command source .base_profile, but I don't need this path, how to delete it?
由于错误，我添加了一个不想使用的路径。
我已经创建了一个名为.base_profile 的文件，使用source .base_profile 命令导出了路径，但是我不需要这个路径，如何删除它？
Maybe the title wasn't so appropriate, but I haven't modified the PATH variable.
I have written this in the .base_profile file:
也许标题不太合适，但我没有修改 PATH 变量。
我在 .base_profile 文件中写了这个：
export MP=$MP/usr/local/mysql/bin
And then used the source command.The problem is with the MP variable, which is not one that I want, it's too long.I want to delete it, how to do it?
然后用source命令。问题是MP变量，不是我想要的，太长了。我想删除它，怎么办？

Do an
做一个
echo $PATH
Then grab with the mouse that part, which looks useful, and append it to:
然后用鼠标抓住那个看起来有用的部分，并将其附加到：
PATH=
So for example - not on an OSX-System:
例如 - 不在 OSX 系统上：
PATH=/home/ramy/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games
If you only sourced the path in one terminal, you can, alternatively, open a new terminal.
如果您只在一个终端中获取路径，您也可以打开一个新终端。
If you added the source-command to one configuration script, you have to remove it there, to get rid of it permananetly.
如果您将 source-command 添加到一个配置脚本中，则必须在那里将其删除，以永久删除它。
