\section functions functions - print or erase functions
\subsection function-synopsis Synopsis
<code>functions [-e] FUNCTIONS...</code>
\subsection functions-description Description
This builtin command is used to print or erase functions.
- <code>-a</code> or <code>--all</code> list all functions, even those whose name start with an underscore.
- <code>-d DESCRIPTION</code> or <code>--description=DESCRIPTION</code> change the description of this function
- <code>-e</code> or <code>--erase</code> causes the specified functions to be erased.
- <code>-h</code> or <code>--help</code> display a help message and exit
- <code>-n</code> or <code>--names</code> list only the names of all defined functions, not their definition
- <code>-q</code> or <code>--query</code> test if the specified functions exist. Does not output anything, but the builtins exit status is the number of functions specified that were not defined.
The default behavior of \c functions when called with no arguments,
is to print the names and definitions of all defined functions. If any
non-switch parameters are given, only the definition of the specified
functions are printed.
Automatically loaded functions can not be removed using functions
-e. Either remove the definition file or change the
$fish_function_path variable to remove autoloaded functions.
The exit status of the functions builtin is the number functions
specified in the argument list that do not exist.
