\section exit exit - exit the shell.
\subsection exit-synopsis Synopsis
exit [STATUS]
\subsection exit-description Description
The exit builtin causes fish to exit. If STATUS is
supplied, it will be converted to an integer and used as the exit
code. Otherwise the exit code will be that of the last command executed.
If exit is called while sourcing a file (using the . builtin) the rest of the file will be skipped,
but the shell itself will not exit.
