0 12 * * * path/to/virtualenv/bin/packt-cli -gd > path/to/log/file 2>&1

Adjust execution time and paths according to your setup. To verify if cron executes the script as expected, run

$ sudo grep CRON /var/log/syslog

Windows

schtasks.exe setup (more info: https://technet.microsoft.com/en-us/library/cc725744.aspx) :

To create the task that will be called at 12:00 everyday, run the following command in cmd (modify all paths according to your setup):

schtasks /create /sc DAILY /tn "grabEbookFromPacktTask" /tr "C:\Users\me\Desktop\GrabPacktFreeBook\grabEbookFromPacktTask.bat" /st 12:00

To check if the "grabEbookFromPacktTask" has been added to all scheduled tasks on your computer:

schtasks /query

To run the task manually:

schtasks /run /tn "grabEbookFromPacktTask"

To delete the task:

schtasks /delete /tn "grabEbookFromPacktTask"

If you want to log all downloads add -l switch to grabEbookFromPacktTask i.e.

schtasks /create /sc DAILY /tn "grabEbookFromPacktTask" /tr "C:\Users\me\Desktop\GrabPacktFreeBook\grabEbookFromPacktTask.bat -l" /st 12:00

If you want to additionaly make command line windows stay open after download add -p switch i.e.

schtasks /create /sc DAILY /tn "grabEbookFromPacktTask" /tr "C:\Users\me\Desktop\GrabPacktFreeBook\grabEbookFromPacktTask.bat -l -p" /st 12:00

Google Drive API Setup

Full info about the Google Drive Python API can be found here.

1. Turn on the Google Drive API

• Use this wizard to create or select a project in the Google Developers Console and automatically turn on the API. Click Continue, then Go to credentials.
• On the Add credentials to your project page, click the Cancel button.
• At the top of the page, select the OAuth consent screen tab. Select an email address, enter a product name if not already set, and click the Save button.
• Select the Credentials tab, click the Create credentials button and select OAuth client ID.
• Select the application type Other, enter the name GoogleDriveManager, and click the Create button.
• Click OK to dismiss the resulting dialog.
• Click the file_download (Download JSON) button to the right of the client ID.
• Move this file next to the config file and rename it to client_secret.json.

2. Create credentials folder:

• Simply, just fire up the script with -sgd argument; During first launch you will see a prompt in your browser asking for permissions, click then allow

packt-cli -sgd

• Or if you're unable to launch browser locally (e.g. you're connecting through SSH without X11 forwarding) use this command once, follow instructions and give permission and later you can use normal command (without --noauth_local_webserver).

packt-cli -c /path/to/config/file.cfg -sgd --noauth_local_webserver

The command parameters number and their order is important!

3. Already done!

• Run the same command as above to claim and upload the eBook to Google Drive.

In case of any questions feel free to ask, happy grabbing!
