# How to use the command line
2530

2631
**`go-feature-flag-cli`** is a command line tool.
2732

2833
## How to evaluate a flag
34+
35+
The evaluate command allows you to evaluate a feature flag or inspect the configuration of your retriever using
36+
`--check-mode`
37+
38+
```shell
39+
go-feature-flag-cli evaluate [OPTIONS]
40+
```
41+
42+
### Key Flags
43+
44+
| Flag | Shorthand | Description | Default |
45+
|----------------|-----------|---------------------------------------------------------------------------------------------------------------------------------|---------|
46+
| `--kind` | k | Kind of configuration source. Determines where to read your flags from | file |
47+
| `--config` | c | Path to the local flag configuration file (⚠️ deprecated, use `--path` instead) | "" |
48+
| `--format` | f | Format of your input file (YAML, JSON or TOML) | yaml |
49+
| `--flag` | | Name of the flag to evaluate | "" |
50+
| `--timeout` | | Timeout in seconds to access your configuration file | 0 |
51+
| `--ctx` | | Evaluation context as a json string | {} |
52+
| `--check-mode` | | Check only mode - when set, the command will not perform any <br/>evaluation and returns the configuration of spanned retriever | false |
53+
54+
Supported values for `--kind` are:
55+
56+
- `file`
57+
- `http`
58+
- `github`
59+
- `gitlab`
60+
- `s3`
61+
- `googleStorage`
62+
- `configmap` (kubernetes)
63+
- `mongodb`
64+
- `bitbucket`
65+
- `azureBlobStorage`
66+
- `postgresql`
67+
68+
**Caution**: We do not support `redis` retriever as for now due
69+
to: https://github.com/thomaspoignant/go-feature-flag/issues/4023.
70+
71+
### Retriever specific flags
72+
73+
The aforementioned `--kind` parameter is used to determine the retriever to use. The semantic meaning of other flags
74+
depends on that one, for
75+
example `--path` parameter is used to specify local file when `--kind` being `file` but when `--kind` being `github` it
76+
is used to specify
77+
the path to the remote file.

the following command:

go-feature-flag-cli evaluate --config="<location_of_your_flag_configuration_file>" --flag="<name_of_your_flag_to_evaluate>" --ctx='<evaluation_ctx_as_json_string>'
31174
```
32175

176+
may be replaced by:
177+
178+
```shell
179+
go-feature-flag-cli evaluate --kind="file" --path="<location_of_your_flag_configuration_file>" --flag="<name_of_your_flag_to_evaluate>" --ctx='<evaluation_ctx_as_json_string>'
180+
```
181+
33182
## How to lint a configuration file
183+
34184
```shell
35185
go-feature-flag-cli lint <location_of_your_flag_configuration_file> --format="<yaml or json or toml>"
