# knife plugin
This plugin adds completion for [knife](https://docs.chef.io/knife.html), a command-line tool
to interact with [Chef](https://chef.io), a platform to automate and manage infrastructure via
code.
To use it, add `knife` to the plugins array in your zshrc file:
```zsh
plugins=(... knife)
```
## Options
- `KNIFE_RELATIVE_PATH`: if set to `true`, the completion script will look for local cookbooks
under the `cookbooks` folder in the chef root directory. It has preference over the other two
options below. **Default:** empty.
- `KNIFE_COOKBOOK_PATH`: if set, it points to the folder that contains local cookbooks, for
example: `/path/to/my/chef/cookbooks`. **Default:** `cookbook_path` field in `knife.rb`
(see below).
- `KNIFE_CONF_PATH`: variable pointing to the `knife.rb` configuration file, for example
`/path/to/my/.chef/knife.rb`. Only used if `$KNIFE_COOKBOOK_PATH` isn't set. If it exists,
`$PWD/.chef/knife.rb` is used instead. Otherwise, if it's set, its value is used.
**Default**: `$HOME/.chef/knife.rb`.
