## Add users to groups
Add each user in `<UserTypeEntity>` to all of the groups specified by `([<GroupRole>] <GroupEntity>)+`.
If `<GroupRole>` is not specified, `member` is assumed.
```
gam <UserTypeEntity> add group|groups
        ([<GroupRole>] [[delivery] <DeliverySetting>] <GroupEntity>)+
```

### Basic Example
Add a user to several groups with different roles.
```
$ gam user testuser1@domain.com add groups owner testgroup1@domain.com manager testgroup2@domain.com member testgroup3@domain.com,testgroup4@domain.com
User: testuser1@domain.com, Add to 4 Groups
  Group: testgroup1@domain.com, Owner: testuser1@domain.com, Added (1/4)
  Group: testgroup2@domain.com, Manager: testuser1@domain.com, Added (2/4)
  Group: testgroup3@domain.com, Member: testuser1@domain.com, Added (3/4)
  Group: testgroup4@domain.com, Member: testuser1@domain.com, Added (4/4)

```

### Advanced Example
Use a CSV file to specify users, groups and roles.
```
# Desired state
$ more UserGroupRole.csv

## Delete users from groups
```
gam <UserTypeEntity> delete group|groups
        [(domain <DomainName>)|(customerid <CustomerID>)|
         (emailmatchpattern [not] <REMatchPattern>)|<GroupEntity>]
```
By default, users will be deleted from all groups of which they are a member, these options allow selection of subsets of groups:
* `domain <DomainName>` - Delete from all groups in the domain `<DomainName>` of which they are a member
* `customerid <CustomerID>` - For resellers, delete from all groups in a resold workspace of which they are a member
* `emailmatchpattern [not] <REMatchPattern>` - Delete from all groups of which they are a member based on (not) matching the group email address
* `<GroupEntity>` - Delete from a specific list of groups

### Basic Examples
Delete a user from all groups to which it belongs.
```
$ gam user testuser1@domain.com delete groups
User: testuser1@domain.com, Delete from 4 Groups
  Group: testgroup1@domain.com, Member: testuser1@domain.com, Deleted (1/4)
  Group: testgroup2@domain.com, Member: testuser1@domain.com, Deleted (2/4)
  Group: testgroup3@domain.com, Member: testuser1@domain.com, Deleted (3/4)
  Group: testgroup4@domain.com, Member: testuser1@domain.com, Deleted (4/4)
```

Delete users from all groups to which they belong. Assume a CSV file NoGroupsUsers.csv with a column labelled primaryEmail
that lists the users.
```
gam csv NoGroupsUsers.csv gam user "~primaryEmail" delete groups
```

### Advanced Example
Use a CSV file to specify users and groups.
```

## Delete external user from groups
There is a user from outside of your domain that you would like to delete from all groups.
```
$ gam user user@external.com delete groups
User: user@external.com, Delete from 0 Groups
```

There is a Goggle issue that causes this to fail for a few external addresses.
To solve this problem, you need the unique ID for the external address;
the following steps show how to do this.

Create a test group.
```
$ gam create group testexternal description "Test External Email Addresses"
Group: testexternal@domain.com, Created
```

Add the external address to that group.
```
$ gam update group testexternal add member user@external.com
Group: testexternal@domain.com, Add 1 Member
  Group: testexternal@domain.com, Member: user@external.com, Added: Role: MEMBER
```

Print the group members of the group to get the unique ID of the external address.
```
$ gam print group-members group testexternal
Getting all Members, Managers, Owners for testexternal@domain.com
group,type,role,id,status,email
testexternal@domain.com,USER,MEMBER,123406166545652215678,,user@external.com
```

Delete the external address from all groups.
```
$ gam user uid:123406166545652215678 delete groups
User: 123406166545652215678, Delete from 2 Groups
  Group: testexternal@domain.com, Member: 123406166545652215678, Deleted (1/2)
  Group: testgroup@domain.com, Member: 123406166545652215678, Deleted (2/2)
```

## Update users group roles and delivery settings
For each user in `<UserTypeEntity>` update their current group role and delivery settings.
```
gam <UserTypeEntity> update group|groups
        [(domain <DomainName>)|(customerid <CustomerID>)]) [<GroupRole>] [[delivery] <DeliverySetting>]
        ([<GroupRole>] [[delivery] <DeliverySetting>] [<GroupEntity>])*
```
By default, update user roles and delivery settings for all groups of which they are a member, these options allow selection of subsets of groups:
* `domain <DomainName>` - Update user role and delivery settings for all groups in the domain `<DomainName>` of which they are a member
* `customerid <CustomerID>` - For resellers, update user role and delivery settings for all groups in a resold workspace of which they are a member
* `<GroupEntity>` - Update user role and delivery settings for a specific list of groups; you can specify different roles and delivery settings for different group lists

```
## Synchronize users group membership
For each user in `<UserTypeEntity>` get their current group membership and do adds and deletes as necessary to match `([<GroupRole>] <GroupEntity>)+`.
If `<GroupRole>` is not specified, `member` is assumed.
```
gam <UserTypeEntity> sync group|groups
        [(domain <DomainName>)|(customerid <CustomerID>)]
        [<GroupRole>] [[delivery] <DeliverySetting>] <GroupEntity>)*
```
By default, users will be synchronized with all groups of which they are a member, these options allow selection of subsets of groups:
* `domain <DomainName>` - Synchronize with all groups in the domain `<DomainName>` of which they are a member
* `customerid <CustomerID>` - For resellers, synchronize with all groups in a resold workspace of which they are a member

## Check users group membership
For each user in `<UserTypeEntity>` check if they are members of the groups in `<GroupEntity>` with a role
in `role <GroupsRoleList>`; if not specified, any role is acceptable.
```
gam <UserTypeEntity> check group|groups
        [roles <GroupRoleList>] [includederivedmembership] [csv] <GroupEntity>
```
By default, only direct membership is checked; include the `includederivedmembership` to check
if a user is a member of a group or one of its sub-groups.

By default, the output is indented keys and values written to stdout;
use the `csv` option to write the output to a CSV file.

A return code of 0 indicates that a user is a member of all of the groups with an acceptable role;
a return code of 29 indicates that the user is not a member of all of the groups.

## Display users group membership
It takes one API call to get the list of groups to which a user belongs.

### Display group names as an indented list
There is one row per group to which a user belongs.
```
gam <UserTypeEntity> show groups
        [(domain <DomainName>)|(customerid <CustomerID>)]
        [roles <GroupRoleList>] nodetails
```

### Display group names in CSV format
There is one row per user/group combination.
```
gam <UserTypeEntity> print groups [todrive <ToDriveAttribute>*]
        [(domain <DomainName>)|(customerid <CustomerID>)]
        [roles <GroupRoleList>] nodetails
```
By default, all groups to which a member belongs are displayed, these options allow selection of subsets of groups:
* `domain <DomainName>` - Limit display to groups in the domain `<DomainName>` of which they are a member
* `customerid <CustomerID>` - For resellers, display all groups in a resold workspace of which they are a member
* `roles <GroupRoleList>` - Limit display to those groups for which the user has a specific role

### Display group details as an indented list
There is one row per group to which a user belongs showing role, status and delivery information.

There is one API call per user/group to get the user's role and delivery settings.
```
gam <UserTypeEntity> show groups
        [(domain <DomainName>)|(customerid <CustomerID>)]
        [roles <GroupRoleList>]
```

By default, all groups to which a member belongs are displayed, these options allow selection of subsets of groups:
* `domain <DomainName>` - Limit display to groups in the domain `<DomainName>` of which they are a member
* `customerid <CustomerID>` - For resellers, display all groups in a resold workspace of which they are a member

### Display group addresses in CSV format
There is one row per user showing the number and list of groups to which a user directly belongs.
```
gam <UserTypeEntity> print groupslist [todrive <ToDriveAttribute>*]
        [(domain <DomainName>)|(customerid <CustomerID>)]
        [delimiter <Character>] [quotechar <Character>]
```
By default, all groups to which a member belongs are displayed, these options allow selection of subsets of groups:
* `domain <DomainName>` - Limit display to groups in the domain `<DomainName>` of which they are a member
* `customerid <CustomerID>` - For resellers, display all groups in a resold workspace of which they are a member

By default, the entries in lists of groups are separated by the `csv_output_field_delimiter' from `gam.cfg`.
* `delimiter <Character>` - Separate list items with `<Character>`

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.
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.

### Display groups and their parents
Display a user's groups and their parents as an indented list.
```
gam <UserTypeEntity> show grouptree
        [(domain <DomainName>)|(customerid <CustomerID>)]
        [roles <GroupRoleList>]
```
By default, all groups to which a member belongs are displayed, these options allow selection of subsets of groups:
* `domain <DomainName>` - Limit display to groups in the domain `<DomainName>` of which they are a member
* `customerid <CustomerID>` - For resellers, display all groups in a resold workspace of which they are a member

By default, all of a users's groups are displayed without role information. Displaying role
information requires an additional API call per user/group combination.
* `roles <GroupRoleList>` - Display groups with role information where the user has one of the specified roles

Display a user's groups and their parents in CSV format.
```
gam <UserTypeEntity> print grouptree [todrive <ToDriveAttribute>*]
        [(domain <DomainName>)|(customerid <CustomerID>)]
        [roles <GroupRoleList>]
        [showparentsaslist [<Boolean>]] [delimiter <Character>]
```
By default, all groups to which a member belongs are displayed, these options allow selection of subsets of groups:
* `domain <DomainName>` - Limit display to groups in the domain `<DomainName>` of which they are a member
* `customerid <CustomerID>` - For resellers, display all groups in a resold workspace of which they are a member

By default, all of a users's groups are displayed without role information. Displaying role
information requires an additional API call per user/group combination.
* `roles <GroupRoleList>` - Display groups with role information where the user has one of the specified roles

By default, the group parent emails and names are displayed in multiple indexed columns.
Use options `showparentsaslist [<Boolean>]` and `delimiter <Character>` to display
the group parent emails and names in two columns as delimited lists .
