CentOS - Oct 2016 - python script from crontab - problems with proper execution

Hi All.

I currently have a problem with proper invocation of a python script with
cron.

non-root $ crontab -l
#Ansible: script_repo_scanner
55 11 * * * /usr/bin/python /path/script_repo_scanner.py --bb_user bb_user
--bb_pass bb_pass --bd_log_dir /path/logs &>
/path/script_repo_scanner.py.log

And in /var/log/cron I see that cron executed the script but there is no
log output in /path/script_repo_scanner.py.log and the script did not
perform his job. So it looks like it has not been run despite entries in
/var/log/cron ;)

When I execute the command

non-root$ /usr/bin/python /path/script_repo_scanner.py --bb_user bb_user
--bb_pass bb_pass --bd_log_dir /path/logs &>
/path/script_repo_scanner.py.log

I get standard output (script logs to stdout) and script does its job.

Any clue what I could be missing?

BR,
Rafal.

Hi Rafal,

You'll want to change the command to

/usr/bin/python /path/script_repo_scanner.py --bb_user bb_user
--bb_pass bb_pass --bd_log_dir /path/logs >>
/path/script_repo_scanner.py.log

Notice that &> is changed to >>

Take care,

Brian Bernard
