Cannot write a crontab to system

[Dominick Rivard]

Hi,

I am trying to execute the following lines of code:

    comment = '# Comment'
    filename = 'filename.tab' if any(platform.win32_ver()) else False

    if filename:
        cron = CronTab(user=getpass.getuser(), tabfile=filename)
    else:
        cron = CronTab(user=getpass.getuser())

    custom_cmd = ' my_cli_name action'

    job = cron.new(command=custom_cmd, comment=comment)
    job.minute.every(ttl / 60)
    job.enable()
    cron.write()

Once it gets to the write() function it fails on read() with error:
    IOError: Read crontab drivard: crontab: must be privileged to use -u

I can from the shell create the cron without a problem.

Environment:
Mac OS Yosemite
pip show python-crontab
---
Name: python-crontab
Version: 1.9.3

How can I make it write to the user crontab?

Regards
Dominick

I previously said it was doing the same error on ubuntu, but I was wrong I retested it and it works on Ubuntu 14.04

Thanks

This error occurs because you specify a user without being root. We've seen this error before.

Don't specify the user or it will attempt to use that user instead of the filename.

Specify user=True if you want it to use the local user.

I can add this detail:

ls /usr/bin/crontab
-rwsr-xr-x 1 root wheel 34K 9 Sep 2014 /usr/bin/crontab

Fixed with user=True

Thanks
