I am developing a backup script in my NAS running a docker container. Inside my container I have cron running with this /etc/crontab:
root@backups-nas:/code# cat /etc/crontab SHELL=/bin/bash PATH=/sbin:/bin:/usr/sbin:/usr/bin MAILTO=root HOME=/ 0 * * * * root /code/backup.sh
I have also installed syslog-ng, so I can look for logs in /var/log/syslog, where my task appears:
root@backups-nas:/code# tail -f /var/log/syslog ==> /var/log/syslog <== Mar 24 19:00:01 backups-nas CRON: (root) CMD (/code/backup.sh)
The content of my script is this:
root@backups-nas:/code# cat backup.sh #!/bin/bash python3 /code/backup.py all >> /code/log/$(date +\%d-\%m-\%Y).log
But when it's o'clock no new log writter in /code/log/$(date +\%d-\%m-\%Y).log and the task is not completed. If I try to execute manually the line of /etc/crontab it works.
What do you think is happening? Thanks in advance
I edited backup.py, starting like this:
#!/usr/local/bin/python3 from sys import argv import datetime
If I run the script directly works, but cron doesn't run it, although the line in /var/log/syslog.
