Calendar selection

• allcalendars - All calendars in a user's calendar list
• primary - The user's primary calendar
• <EmailAddress> - The address of a calendar in a user's calendar list
• <UniqueID> - The uniqueid of a calendar in a user's calendar list
• courses <CourseIDList>- The calendars associated with a list of courses
• courses_with_teacher <UserItem> - The calendars associated with courses with <UserItem> as a teacher
• my_courses_as_teacher - The calendars associated with the User from <UserTypeEntity> as a teacher
• courses_with_student <UserItem> - The calendars associated with courses with <UserItem> as a student
• my_courses_as_student - The calendars associated with the User from <UserTypeEntity> as a student
• coursestates <CourseStateList> - Used with the previous four options to select courses in a particular state; the default is all
• resource <ResourceID> - The calendar associated with a resource ID
• resources <ResourceIDList> - The calendars associated with a list of resource IDs
• calendars (<CalendarList> | <FileSelector> | <CSVFileSelector> | <CSVkmdSelector> | <CSVDataSelector>) - A collection of calendars: Collections of Items
• <CalendarSelectProperty>+ - The calendars in a user's calendar list with the specified properites

Manage calendar access

gam <UserTypeEntity> add calendaracls <UserCalendarEntity>
        <CalendarACLRole> <CalendarACLScopeEntity> [sendnotifications <Boolean>]
gam <UserTypeEntity> update calendaracls <UserCalendarEntity>
        <CalendarACLRole> <CalendarACLScopeEntity> [sendnotifications <Boolean>]
gam <UserTypeEntity> delete calendaracls <UserCalendarEntity>
        [<CalendarACLRole>] <CalendarACLScopeEntity>

By default, when you add or update a calendar ACL, notification is sent to the members referenced in the <CalendarACLScopeEntity>. Use sendnotifications false to suppress sending the notification.

Display calendar access

gam <UserTypeEntity> info calendaracls <UserCalendarEntity>
        <CalendarACLScopeEntity> [formatjson]
gam <UserTypeEntity> show calendaracls <UserCalendarEntity>
        [noselfowner]
        [formatjson]

Option noselfowner suppresses the display of ACLs that reference the calendar itself as its owner.

By default, Gam displays the information as an indented list of keys and values.

• formatjson - Display the fields in JSON format.

gam <UserTypeEntity> print calendaracls <UserCalendarEntity> [todrive <ToDriveAttribute>*]
        [noselfowner] (addcsvdata <FieldName> <String>)*
        [formatjson [quotechar <Character>]]

Option noselfowner suppresses the display of ACLs that reference the calendar itself as its owner.

Add additional columns of data from the command line to the output

• addcsvdata <FieldName> <String>

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.

Transfer calendar ownership

You can transfer ownership of calendars from one user to another; only non-primary calendars owned by the source user can be transferred.

gam <UserTypeEntity> transfer calendars|seccals <UserItem> [<UserCalendarEntity>]
        [keepuser | (retainrole <CalendarACLRole>)] [sendnotifications <Boolean>]
        [noretentionmessages]
        [<CalendarSettings>] [append description|location|summary] [noupdatemessages]
        [deletefromoldowner] [addtonewowner <CalendarAttribute>*] [nolistmessages]

If <UserCalendarEntity> is not specified, all of a user's owned secondary calendars will be transferrdd.

By default, the users in <UserTypeEntity> retain no role in the transferred calendars.

• keepuser - The users in <UserTypeEntity> retain their ownership.
• retainrole <CalendarACLRole> - The users in <UserTypeEntity> retain the specified role.
• noretentionmessages - Suppress the original owner role retention messages.

By default, when you add or update a calendar ACL, a notification is sent to the affected users; use sendnotifications false to suppress sending the notifications.

You can update calendar settings as part of the transfer. In description, location and summary, #email#, #user# and #username# will be replaced by the original owner's full email address or just the name portion; #timestamp# will be replaced by the current date and time.

• <CalendarSettings> - The value specified will replace the existing value.
• append description|location|summary - The specified value will be appended to the existing value.
• noupdatemessages - Suppress the settings update messages.

You can manipulate the old and new owner's calendar lists.

• deletefromoldowner - Delete the calendar from the old owner's calendar list
• addtonewowner <CalendarAttribute>* - Add the calendar to the new owner's calendar list; optionally specify attributes
• nolistmessages - Suppress the calendar list add/delete messages.

Example

Transfer a secondary calendar from oldowner to newowner. Remove the calendar from the old owner's calendar list and add to the new owner's calendar list.

gam user [email protected] transfer calendars [email protected] [email protected] removefromoldowner addtonewowner

Transfer ownership of all non-primary calendars from oldowner to newowner; append a message to the calendar description noting the old owner and the time of transfer.

gam user [email protected] transfer calendars [email protected] minaccessrole owner description "(Transferred from #user# on #timestamp#)" append description
