+
+fish_prompt - define the appearance of the command line prompt
+==============================================================
+
+Synopsis
+--------
+
+::
+
+  function fish_prompt
+      ...
+  end
+
+
+Description
+-----------
+
+By defining the ``fish_prompt`` function, the user can choose a custom prompt. The ``fish_prompt`` function is executed when the prompt is to be shown, and the output is used as a prompt.
+
+The exit status of commands within ``fish_prompt`` will not modify the value of :ref:`$status <variables-status>` outside of the ``fish_prompt`` function.
+
+``fish`` ships with a number of example prompts that can be chosen with the ``fish_config`` command.
+
+
+Example
+-------
+
+A simple prompt:
+
+
+
+::
+
+    function fish_prompt -d "Write out the prompt"
+        printf '%s@%s%s%s%s> ' (whoami) (hostname | cut -d . -f 1) \
+        		(set_color $fish_color_cwd) (prompt_pwd) (set_color normal)
+    end
+
