Hi, i have curator in linux environment which is in live so i can't experiment with that . i need one clarification regarding the command i have curator files in `/home/hero/.curator` . If i run the below cron job command whether it will run in dry-run mode correctly or it will delete the indices in the live environment. ``` * * * * * /home/hero/.curator/curator --dry-run --config curator.yml delete .yml >> /home/hero/.curator/log.txt ``` And also i want to know whether the command is correct or not, because i am sending the cron job logs to log.txt? Thanks ---

If you're using the `--dry-run` flag in the cron job, it will still be a dry run. No changes will be made. As far as logging is concerned, that will depend on how you have logging set in your `curator.yml` file. If it's unset, then yes, your logs will go to `/home/hero/.curator/log.txt`. If you have chosen a log file in the configuration, then that's where your log files will go. ---

Thanks for your time @theuntergeek ``` * * * * * /home/hero/.curator/curator --dry-run --config curator.yml delete .yml >> /home/hero/.curator/log.txt ``` Is it is good approach to send the command like this in cron job or i have to wrap it a bash script? If it is script how i have to wrap it ? Can you pls give me a example for above scenario? Thanks ---

It's totally fine to send the entire command in cron, just like you have here. The older, Curator v3 approach had very long command lines, which could sometimes cause errors in cron. You shouldn't have that problem with the current version of Curator. ---

``` * * * * * /home/hero/.curator/curator --dry-run --config curator.yml delete .yml >> /home/hero/.curator/log.txt ``` When i used the above command in crontab it is creating a log.txt but nothing is there in it. It is creating an empty file ? How to solve this? Thanks ---

Is Curator writing its output to stdout or stderr? As configured you're only capturing stdout to the file. ---
