## Display drive activity
```
gam <UserTypeEntity> print driveactivity [todrive <ToDriveAttributes>*]
        [(fileid <DriveFileID>)|(folderid <DriveFolderID>)|
         (drivefilename <DriveFileName>)|(drivefoldername <DriveFolderName>)|
         (query <QueryDriveFile>)]
        [([start|starttime <Date>|<Time>] [end|endtime <Date>|<Time>])|(range <Date>|<Time> <Date)|<Time>|
         yesterday|today|thismonth|(previousmonths <Integer>)]
        [action|actions [not] <DriveActivityActionList>]
        [consolidationstrategy legacy|none]
        [idmapfile <FileName>|(gsheet <UserGoogleSheet>) [charset <String>] [columndelimiter <Character>] [noescapechar <Boolean>]  [quotechar <Character>]]
        [stripcrsfromname] [formatjson [quotechar <Character>]]
```

By default, drive activity for all files in the top level of My Drive will be displayed.
* `fileid <DriveFileID>` - Display drive activity for file `<DriveFileID>`
* `folderid <DriveFolderID>` - Display drive activity for all files in folder `<DriveFolderID>`
* `drivefilename <DriveFileName>` - Display drive activity for the file with name `<DriveFolderID>`
* `drivefoldername <DriveFolderName>` - Display drive activity for all files in the folder  with name `<DriveFolderName>`
* `query`  - Display drive activity for all files/folders selected by the query

Activities can be filtered by time.
* `start|starttime <Date>|<Time>` - Display activities that occurred on or after the specifed `<Date>|<Time>`
* `end|endtime <Date>|<Time>` - Display activities that occurred on or before the specifed `<Date>|<Time>`
* `range <Date>|<Time> <Date>|<Time>` - Equivalent to `start <Date>|<Time> end <Date>|<Time>`
* `yesterday` - Display activities that occurred yesterday
* `today` - Display activities that occurred today
* `thismonth` - Display activities that occurred in the current calendar month up to the current time
* `previousmonths <Integer>` - Display activities that occurred in the 1 to 6  months previous to the current month

Activities can be filtered by action.
Google does the filtering.
* `action|actions <DriveActivityActionList>` - Only display activities with the specified actions; by default, all actions are displayed
* `action|actions not <DriveActivityActionList>` - Only display activities without the specified actions; by default, all actions are displayed

The API only returns a permissionId and user name for each event but no user email address. To get an email address perform the
following command to generate a file that contains the email address and permissionId for all users. You can substitute for `all users` if desired.
```
gam config auto_batch_min 1 redirect csv DriveSettings.csv multiprocess all users print drive settings fields permissionid
```
Then, use the `idmapfile DriveSettings.csv` option to have Gam generate a `user.emailAddress` column. The columns `email' and `permissionId`
must be present in the file.

By default, Gam calls the API with a consolidation strategy of `none`; use these options to alter that behavior
* `consolidationstrategy legacy` - The individual activities are consolidated using the legacy strategy
* `consolidationstrategy none` - The individual activities are not consolidated; this is the default

The API only returns a userId for each event but no user name or  email address. To get a name and email address perform the
following command to generate a file that contains the email address and permissionId for all users. You can substitute for `all users` if desired.
```
gam redirect csv ./Users.csv print users fields primaryemail,id,name
```
Then, use the `idmapfile Users.csv` option to have Gam generate a `user.emailAddress` column. The columns `primaryEmail' and `id`
must be present in the file; the column `name.fullName` will be used if present.

If you don't use the `idmapfile` option, Gam makes an additional API call per user to get the name and email address.

The `stripcrsfromname` option strips nulls, carriage returns and linefeeds from drive file names.
Use this option if you discover filenames containing these special characters; it is not common.

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.

## Display drive settings
```
gam <UserTypeEntity> print drivesettings [todrive <ToDriveAttribute>*]
        [allfields|<DriveSettingsFieldName>*|(fields <DriveSettingsFieldNameList>)]
        [delimiter <Character>] [showusagebytes]
gam <UserTypeEntity> show drivesettings
        [allfields|<DriveSettingsFieldName>*|(fields <DriveSettingsFieldNameList>)]
        [delimiter <Character>] [showusagebytes]
```
If no fields are selected, these fields will be displayed:
    `name,appInstalled,largestChangeId,limit,maxUploadSize,permissionId,rootFolderId,usage,usageInDrive,usageInDriveTrash`

By default, these fields are displayed in formatted form with units: ```usage,usageInDrive,usageInDriveTrash```.

The option `showusagebytes` also displays the following fields in bytes ```usageBytes,usageInDriveBytes,usageInDriveTrashBytes```.

This will be most useful with `print` as the rows can be sorted based on the `usagexxxBytes` columns.
