\section{To Reload Your \texttt{.bashrc} File}

\lettrine{S}{ometimes} you add something to your \texttt{.bashrc} file (such as a new bash alias)\index[concepts]{bash alias} and you need to reload it. Of course, this file is reloaded every time you log in, but you may not wish to log out and then log back in if you are in the middle of important work. There are few different ways to do this:

\begin{Verbatim}[]
source ~/.bashrc
\end{Verbatim}
\index{source}

and of course a shorter way:

\begin{Verbatim}[]
. ~/.bashrc
\end{Verbatim}
