[clug] IO redirection

In fish, the following is a valid command.
{
echo Testing.
}

So I put that command into a "Test.txt" text file.

And in a terminal window, I entered the following.
{
exec <Test.txt
}

Resulting in the following screen output.
{
        exec -- execute command in current process

    Synopsis
        exec COMMAND [OPTIONS...]

    Description
        exec replaces the currently running shell with a new command. On
        successful completion, exec never returns. exec cannot be used 
inside
        a pipeline.

    Example
        exec emacs starts up the emacs text editor, and exits fish. When
        emacs exits, the session will terminate.


}

What is the appropriate way to take instructions from a file, and do them?

Yes, that worked fine!
