Hello @syarif1

As per the error “Permission denied”, it seems like the execute permissions are missing from the script. Could you please add the execute permission to your script and try again?

Thanks

Hello Manmeet

How do I add permissions for file access?
is it using chown -R astro:astro <fille_name>?

but unfortunately the astro user does not exist.

Thanks

Hey @syarif1

On your local machine, you can simply give execute permission to the script. Like this:

chmod +x dags/bash_operator/scripts/create_dir.sh

There is no need to change the owner of the script, just giving execute permissions should resolve the error. Let me know if you still face the issue.

Thanks
