bash: Override noclobber setting.

[indigowinged]

Take into account the main readme for this section. README first.

noclobber setting in bash prevents a file from being overwritten.

For example if oneworld file is written you would see the following:

$ echo Hello World > oneworld
-bash: oneworld: cannot overwrite existing file

If you know it is safe to write to the oneworld file, you can override the write using the following:

$ echo One nation under a groove >| oneworld
$ cat oneworld
One nation under a groove
