Unless you want to print them out on separate lines. – Perplexabot Jun 22 '19 at 18:49

Thanks, it worked.. Also I noticed I beginning the script with #!/bin/sh which Ubuntu it seems not the way. Changed it to #!/bin/bash. – Emmanual Jun 22 '19 at 19:01

1@Emmanual Arrays are a bash extension, not available in all shells. In recent versions of Ubuntu, [/bin/sh is dash, a much more basic shell](https://wiki.ubuntu.com/DashAsBinSh). – Gordon Davisson Jun 22 '19 at 19:16

@GauravSingh, I would have but this is really a duplicate and should be flagged. – Perplexabot Jun 22 '19 at 19:34

1"Thanks, it worked" is not an answer. You should write what you did instead. – Gaurav Singh Jun 22 '19 at 19:40
