I was installing Swift on my Linux Mint 17 Qiana and while writing a path to it I made an error: instead of writing

```
$ export PATH=/home/alex/swift/usr/bin/:"${PATH}"

```

I wrote

```
$ export PATH=/home/alex/swift/usr/bin/:"#{PATH}"

```

and now, when I run

```
$ echo $PATH

```

it returns me the following:

```
/home/alex/swift/usr/bin/:/home/alex/swift/usr/bin/:#{PATH}

```

How can I fix that?
