\section source . - Evaluate contents of file. \subsection source-synopsis Synopsis <tt>. FILENAME</tt> \subsection source-description Description Evaluates the commands of the specified file in the current shell. This is different from starting a new process to perform the commands (i.e. <tt>fish < FILENAME</tt>) since the commands will be evaluated by the current shell, which means that changes in environment variables, etc., will remain. \subsection source-example Example <tt>. ~/.fish</tt> causes fish to reread its initialization file.
