scr.sh: 3: Syntax error: word unexpected (expecting ")")

I’m doing a task, but I got an error: scr.sh: 3: Syntax error: word unexpected (expecting ")"). When I try to run my schell script on my local computer server, it works, but on the helios ssh server it return an error. Here’s my test code:

#!/bin/bash

arr=(kitten dog parrot)
for i in ${arr[@]}
do
        echo $i
done

I tried to declare array like this:
arr=("kitten" "dog" "parrot"), it was the same error.

Using declare -a arr didn’t work

I run it like this:

sh scr.sh

>Solution :

The problem is how you run the script. You tell it to use sh instead of bash. Instead do

bash scr.sh

or make the file executable

chmod +x scr.sh

and then you can run it without manually specifying the scripting language every time:

./scr.sh
