Remove functions matching a pattern
unfunction -m "[pattern]*"
Force removal without errors for undefined names
unfunction -f [function_name]
说明
unfunction is a zsh builtin that removes the definition of one or more shell functions from the current session. After removal, calling the function name will result in a "command not found" error unless an external command or alias with the same name exists. This is the zsh equivalent of unset -f in bash and is useful for cleaning up function definitions, reloading modified function files, or undoing autoloaded functions.
参数
- -m
- Treat each _name_ as a pattern (using standard zsh pattern-matching) and remove all functions whose names match.
- -f
- Suppress errors when a given name does not correspond to a defined function.
