Is there a reason you're using a string variable instead of an array? – Charles Duffy May 10 '21 at 19:35

`host_list=( [email protected] [email protected] [email protected] )` would be more sensible; then you can just `for host in "${host_list[@]}"; do ...` – Charles Duffy May 10 '21 at 19:36

In evaluating answers in the linked duplicates, keep [BashPitfalls #50](https://mywiki.wooledge.org/BashPitfalls#hosts.3D.28_.24.28aws_....29_.29) in mind. `array=( $string )` is an antipattern -- while commonly used, it introduces bugs. – Charles Duffy May 10 '21 at 19:38
