\subsection functions-description Description
|
|
|
|
\c functions prints or erases functions.
|
|
|
|
The following options are available:
|
|
|
|
- <code>-a</code> or <code>--all</code> lists all functions, even those whose name start with an underscore.
|
|
- <code>-c OLDNAME NEWNAME</code> or <code>--copy OLDNAME NEWNAME</code> creates a new function named NEWNAME, using the definition of the OLDNAME function.
|
|
- <code>-d DESCRIPTION</code> or <code>--description=DESCRIPTION</code> changes 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> displays a help message and exits.
|
|
- <code>-n</code> or <code>--names</code> lists the names of all defined functions.
|
|
- <code>-q</code> or <code>--query</code> tests if the specified functions exist.
|
|
|
|
The default behavior of <code>functions</code>, when called with no arguments,
|
|
is to print the names of all defined functions. Unless the \c -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 <code>functions
|
|
-e</code>. Either remove the definition file or change the
|
|
$fish_function_path variable to remove autoloaded functions.
|
|
|
|
Copying a function using \c -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 <code>functions -d</code>.
|
|
|
|
The exit status of \c functions is the number of functions
|
|
specified in the argument list that do not exist, which can be used in
|
|
concert with the \c -q option.
|
|
|
|
\subsection functions-example Examples
|
|
|
|
<code>functions -n</code> displays a list of currently-defined functions.
|
|
|
|
<code>functions -c foo bar</code> copies the \c foo function to a new function called
|
|
<code>bar</code>.
|
|
|
|
<code>functions -e bar</code> erases the function <code>bar</code>.
