#### Clobber
If option `noclobber` is set, redirect `>filename` will not overwrite an existing file. This can be overridden by `>| filename`.
```plaintext
set -o noclobber # enable noclobber
set +o noclobber # disable noclobber
```
For those new to BashShell, not that it is a little counterintuitive that `-o` enables and `+o` disables. Likely `-o` came first and then `+o` is an intuitive opposite to `-o`, (though I don't know).
