+ On execution of the operator the task will up for retry when exception is
raised.
+ However if a command exists with non-zero value Airflow will not recognize
+ it as failure unless explicitly specified in the beggining of the script.
+ Example:
+ bash_command = "python3 script.py '{{ next_execution_date }}'"
+ when executing command exit(1) the task will be marked as success.
+ bash_command = "set -e; python3 script.py '{{ next_execution_date }}'"
+ when executing command exit(1) the task will be marked as up for
retry.
Review comment:
Also this so that exit(1) is rendered as code/mono-spaced
```suggestion
when executing command ``exit(1)`` the task will be marked as up for
retry.
```
