Remove path from environment variables

Question

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? Maybe the title wasn't so appropriate, but I haven't modified the PATH variable. I have written this in the .base_profile file: ``` 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?

Accepted Answer

Do an

```
echo $PATH
```

Then grab with the mouse that part, which looks useful, and append it to:

```
PATH=
```

So for example - not on an OSX-System:

```
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.

If you added the source-command to one configuration script, you have to remove it there, to get rid of it permananetly.
