## Policies
These are the supported policies GAM can show today.
See: https://cloud.google.com/identity/docs/concepts/supported-policy-api-settings
## Display Cloud Identity Policies
Display selected policies.
```
gam info policies <CIPolicyEntity>
[nowarnings] [noappnames] [noidmappimg]
[formatjson]
```
Select policies::
* `polices/<String>` - A policy name, `policies/ahv4hg7qc24kvaghb7zihwf4riid4`
* `settings/<String>` - A policy setting type, `settings/workspace_marketplace.apps_allowlist`
* `<String>` - A policy setting type, `workspace_marketplace.apps_allowlist`
By default, policy warnings are displayed, use the `nowarnings` option to suppress their display.
By default, additional API calls are made for `settings/workspace_marketplace.apps_allowlist`
to get the application name for the application ID. Use option `noappnames` to suppress these calls.
By default, additional API calls are made to add the `policyQuery/groupEmail` and `policyQuery/orgUnitPath` fields
that are mapped from the `policyQuery/group` and `policyQuery/orgUnit` fields. Use option `noidmapping'
to suppress these calls and not add the additional fields.
By default, Gam displays the information as an indented list of keys and values.
* `formatjson` - Display the fields in JSON format.
Display all or filtered policies.
```
gam show policies
[filter <String>] [nowarnings] [noappnames] [noidmappimg]
[group <REMatchPattern>] [ou|org|orgunit <REMatchPattern>]
[formatjson]
```
By default, all policies are displayed.
* `filter <String>` - Display filtered policies, See https://cloud.google.com/identity/docs/reference/rest/v1beta1/policies/list
* `group <REMatchPattern>` - Only display policies whose group email address matches the `<REMatchPattern>`
* `ou|org|orgunit <REMatchPattern>` - Only display policies whose OU path matches the `<REMatchPattern>`
By default, policy warnings are displayed, use the `nowarnings` option to suppress their display.
By default, additional API calls are made for `settings/workspace_marketplace.apps_allowlist`
to get the application name for the application ID. Use option `noappnames` to suppress these calls.

By default, Gam displays the information as an indented list of keys and values.
* `formatjson` - Display the fields in JSON format.
```
gam print policies [todrive <ToDriveAttribute>*]
[filter <String>] [nowarnings] [noappnames] [noidmappimg]
[group <REMatchPattern>] [ou|org|orgunit <REMatchPattern>]
[formatjson [quotechar <Character>]]
```
By default, all policies are displayed:
* `filter <String>` - Display filtered policies, See https://cloud.google.com/identity/docs/reference/rest/v1beta1/policies/list
* `group <REMatchPattern>` - Only display policies whose group email address matches the `<REMatchPattern>`
* `ou|org|orgunit <REMatchPattern>` - Only display policies whose OU path matches the `<REMatchPattern>`
By default, policy warnings are displayed, use the `nowarnings` option to suppress their display.

By default, additional API calls are made for `settings/workspace_marketplace.apps_allowlist`
to get the application name for the application ID. Use option `noappnames` to suppress these calls.
By default, Gam displays the information as columns of fields; the following option causes the output to be in JSON format,
* `formatjson` - Display the fields in JSON format.
By default, when writing CSV files, Gam uses a quote character of double quote `"`. The quote character is used to enclose columns that contain
the quote character itself, the column delimiter (comma by default) and new-line characters. Any quote characters within the column are doubled.
When using the `formatjson` option, double quotes are used extensively in the data resulting in hard to read/process output.
The `quotechar <Character>` option allows you to choose an alternate quote character, single quote for instance, that makes for readable/processable output.
`quotechar` defaults to `gam.cfg/csv_output_quote_char`. When uploading CSV files to Google, double quote `"` should be used.
### Examples
Print all service status policies.
```
gam redirect csv ./ServiceStatusPolicies.csv print policies filter "setting.type.matches('.*service_status')"
```
Print Drive external sharing policies.
```
gam redirect csv ./DriveExternalSharingPolicies.csv print policies filter "setting.type.matches('settings/drive_and_docs.external_sharing')"
```
Print all polices that apply directly to the OU "/Staff".
```
gam redirect csv ./StaffPolicies.csv print policies ou "^/Staff$"
```
Print all polices that apply to the OU "/Staff" and its sub-OUs.
```
gam redirect csv ./StaffPolicies.csv print policies ou "^/Staff"
```
