Shell redirection operator '> &'

> Name
>! Name
> & Name
> &! Name
The file Name Is used as standard output. If the file does not
Exist then it is created; if the file exists, it is truncated,
Its previous contents being lost.

If the shell variableNoclobberIs set, then the file must not
Exist or be a character special file (e.g., a terminal or
'/Dev/null') or an error results. This helps prevent acciden-
Tal destruction of files. In this case '! 'Forms can be
Used to suppress this check.

The forms involving '&' route the diagnostic output into
Specified file as well as the standard output.NameIs
Expanded in the same way as '<'input filenames are.
