How could I write a command in LaTeX, so after compiling it will be shown as a text in PDF and not executed?
For Example, I would write \it This is how you write in italic and the compiled pdf would contain the exact same text between the quotation marks without \it being executed.
You can put them in the verbatim environment.
\begin{verbatim}
\it This is how you write in italic
\end{verbatim}
P.S. If you need to put them in-line, you can put them in the \verb== environment:
\verb=\it This is how you write in italic=
= and = as delimiters.

showexpl package that loads listings package might be interesting for you as it provides more sophisticated features as follows.
\documentclass[preview,border=12pt,12pt]{standalone}
\usepackage{accsupp}
\newcommand*{\noaccsupp}[1]{\BeginAccSupp{ActualText={}}#1\EndAccSupp{}}
\usepackage{xcolor}
\usepackage{showexpl}
\lstdefinestyle{Common}
{
language={[LaTeX]TeX},
numbers=left,
numbersep=1em,
numberstyle=\tiny\noaccsupp,
frame=single,
framesep=\fboxsep,
framerule=\fboxrule,
rulecolor=\color{red},
xleftmargin=\dimexpr\fboxsep+\fboxrule,
xrightmargin=\dimexpr\fboxsep+\fboxrule,
breaklines=true,
breakindent=0pt,
tabsize=2,
columns=flexible,
includerangemarker=false,
rangeprefix=//\ ,
}
\lstdefinestyle{A}
{
style=Common,
backgroundcolor=\color{yellow!10},
basicstyle=\scriptsize\ttfamily,
keywordstyle=\color{blue}\bf,
identifierstyle=\color{black},

}
\usepackage{graphicx}
\begin{document}
\section*{lstinline}
\lstinline[style=A]|\LaTeX\ is fun.|
\section*{lstlisting}
\begin{lstlisting}[style=A]
\LaTeX\ is also fun in displayed mode.
\end{lstlisting}
\section*{LTXexample}
\LTXexample[style=A]

The ltxdoc document class, which is used for LaTeX documentation, contains the following definition:
\DeclareRobustCommand\cs[1]{\texttt{\char`\\#1}}
With this definition you can use \cs{textit} and the output will contain \textit.
\textit{}. Compare \cs{textit{}} and \cs{textit\{\}} with \verb|\textit{}|

ltxdoc provides also macros \marg and \oarg for mandatory and optional arguments. You'd write something like \cs{textit}\marg{italic text}

If you want to accomplish this inside a section title, it doesn't work with \verb|\it| AFAIK. However, instead, you could use \textbackslash it\ { \ }. to get \it{} printed.
verbatimenvironment if you have a lot of text or you can use\verb|\it|. – Sigur Jan 24 '14 at 13:21\verb+\it+and NO!!!!! you do NOT use\itto get italic!!! Please to not teach this to users. Use\textit{...}or if it is for emphasizing\emph{...}.\itisTeXand should not be used in LaTeX – daleif Jan 24 '14 at 13:23\itshapeis also acceptable as a switch. – Steven B.
