$PATH variable on Mac OS 10.6 Server keeps resetting back
提问by jaycode
In a terminal window I run:
在终端窗口中，我运行：
export PATH=$PATH:/usr/local/mysql/bin>> ~/.bash_profile
导出 PATH=$PATH:/usr/local/mysql/bin>> ~/.bash_profile
Then when I echo $PATH the new path shows alright.
然后当我 echo $PATH 新路径显示正常。
But if I close that window, open another window, the path disappears!
但是如果我关闭那个窗口，打开另一个窗口，路径就会消失！

回答by Quentin
The command you have will set the path and then put the output from that command at the end of your .bash_profile.
您拥有的命令将设置路径，然后将该命令的输出放在 .bash_profile 的末尾。
You want to put the command itself into the .bash_profile.
您想将命令本身放入 .bash_profile。
echo 'export PATH=$PATH:/usr/local/mysql/bin' >> ~/.bash_profile
It won't take effect until you start a new terminal session.
在您开始新的终端会话之前，它不会生效。

You don't need to start a new Terminal session in order to apply the changes to the ~/.bash_profile.
您无需启动新的终端会话即可将更改应用于 ~/.bash_profile。
Just type in the Terminal
只需在终端输入
source ~/.bash_profile

You need to save the
你需要保存
export PATH=$PATH:/usr/local/mysql/bin
in the .bash_profile, as you're trying. However, the export statement is not just displayed text, so appending it won't work. Use an editor to do it.
在 .bash_profile 中，正如您正在尝试的那样。但是，export 语句不仅仅是显示的文本，因此附加它是行不通的。使用编辑器来完成。
