These might not be issues yet, but they make the script more fragile. Also by fixing them we give a better example to future readers, who might copy/paste or otherwise re-use snippets from our script. - Use "read -r", since we don't ever want read to be interpreting '\' characters as escape sequences... - Quote variables, to deal with spaces properly. - Use $() instead of the older and harder-to-nest ``. - Get rid of superfluous "$" prefixes inside arithmetic $(()).

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
