$PATH variable on Mac OS 10.6 Server keeps resetting back

In a terminal window I run:

export PATH=$PATH:/usr/local/mysql/bin>> ~/.bash_profile

Then when I开发者_开发知识库 echo $PATH the new path shows alright.

But if I close that window, open another window, the path disappears!

How to change the PATH variable?

The command you have will set the path and then put the output from that command at the end of your .bash_profile.

You want to put the command itself into the .bash_profile.

echo 'export PATH=$PATH:/usr/local/mysql/bin' >> ~/.bash_profile

It won't take effect until you start a new terminal session.

You don't need to start a new Terminal session in order to apply the changes to the ~/.bash_profile.

Just type in the Terminal

    source ~/.bash_profile

You need to save the

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.
