Here’s how to install it:

In your `.bash_profile` add the following:

Thanks

@dwaite and others for `$@` instead of `$0 $1 …`.

    Christian Neukirchen suggested

    #!/bin/sh
    eval "$@"
    

    … but that runs each line in its own shell.

  2. Hmm… I think Christian makes an annoyingly good point:

    $ export FOO=foo
    $ echo $FOO
    

    When it should print `foo`.

    export FOO=foo
    $ echo $FOO
    foo
