I could verify this behaviour on Ubuntu 16.04.

I will investigate into this. In the meantime, you can start the script using bash as the shell.

Thanks for reporting this issue.

I developed this shell script as a bash shell script. Interestingly RHEL and CentOS reference the "sh" to "bash" which allows users on those distributions to call the script with "sh" as the shell.

On Debian and its deriving distributions it seems that "sh" is linked to "dash". Apparently, dash interprets the brackets differently then bash.

I will check if it is possible to modify the script in a way it runs on both shells.

In the meantime, where you able to start the script using "bash" as the shell?

Yes it works with bash
