-`-a` or `--all` lists all functions, even those whose name starts with an underscore.
-`-c OLDNAME NEWNAME` or `--copy OLDNAME NEWNAME` creates a new function named NEWNAME, using the definition of the OLDNAME function.
-`-d DESCRIPTION` or `--description=DESCRIPTION` changes the description of this function.
-`-e` or `--erase` causes the specified functions to be erased.
-`-D` or `--details` reports the path name where each function is defined or could be autoloaded, `stdin` if the function was defined interactively or on the command line or by reading stdin, and `n/a` if the function isn't available. If the `--verbose` option is also specified then five lines are written:
-# the pathname as already described,
-# `autoloaded`, `not-autoloaded` or `n/a`,
-# the line number within the file or zero if not applicable,
-# `scope-shadowing` if the function shadows the vars in the calling function (the normal case if it wasn't defined with `--no-scope-shadowing`), else `no-scope-shadowing`, or `n/a` if the function isn't defined,
-# the function description minimally escaped so it is a single line or `n/a` if the function isn't defined.
You should not assume that only five lines will be written since we may add additional information to the output in the future.
-`-n` or `--names` lists the names of all defined functions.
-`-q` or `--query` tests if the specified functions exist.
-`-v` or `--verbose` will make some output more verbose.
-`-H` or `--handlers` will show all event handlers.
-`-t` or `--handlers-type TYPE` will show all event handlers matching the given type
The default behavior of `functions`, when called with no arguments, is to print the names of all defined functions. Unless the `-a` option is given, no functions starting with underscores are not included in the output.
If any non-option parameters are given, the definition of the specified functions are printed.
Automatically loaded functions cannot be removed using `functions -e`. Either remove the definition file or change the $fish_function_path variable to remove autoloaded functions.
Copying a function using `-c` copies only the body of the function, and does not attach any event notifications from the original function.
Only one function's description can be changed in a single invocation of `functions -d`.
The exit status of `functions` is the number of functions specified in the argument list that do not exist, which can be used in concert with the `-q` option.

\fish
functions -n
# Displays a list of currently-defined functions
functions -c foo bar
# Copies the 'foo' function to a new function called 'bar'
