[Tex/LaTex] Is there way to make horizontal line on the top of the page that contains only a page number

fancyhdrheader-footerrules

I tried to write a book of the following style: Is there a way to modify the upper horizontal line such that it does not have the word "Sisältö" or any other text except page numbers?

\documentclass[10pt]{book}

\usepackage[utf8]{inputenc}
\usepackage[finnish]{babel}

\usepackage{blindtext}

\usepackage[a5paper]{geometry}
%\usepackage[a5paper, top=2in, bottom=1.5in, left=1in, right=1in]{geometry}

\usepackage{scrextend}
\changefontsizes{10.0pt}  % Change base font size

\usepackage{lettrine}
\usepackage{fancyhdr}

\fancyhead[LE,RO]{\thepage}
\fancyfoot{}
\fancyhead[RO,LE]{\thepage}
\fancyhead[LO]{\leftmark}
\fancyhead[RE]{\rightmark}

\cfoot{} % get rid of the page number 

\linespread{1.3}
\vbadness=20000
\pagestyle{fancy}
\begin{document}
\tableofcontents
\newpage
\section*{Chapter one}
\addcontentsline{toc}{section}{beginning}
First lines.

\newpage

\section*{Chapter two}
\addcontentsline{toc}{section}{somewhere}
Some text.

\newpage

\section*{Chapter two}
\addcontentsline{toc}{section}{end}
The end.
\end{document}

Best Answer

If you only want the rule and the page number in the header, with nothing in the footer, do

\pagestyle{fancy}
\fancyhf{} % clear all fields
\fancyhead[RO,LE]{\thepage}

That's all. Don't set anything else related to fancyhdr.
