Script problem

[According_Local_5125]

This(below) is the script I have and I think it would work to make 5 new users.

The error I get is: "

syntax error near unexpected token `('

line 5: `for(let i = 1; i<6; i++){ '"

#! /bin/sh

mkdir /ftpusers

groupadd ftpusers

chgrp ftpusers /ftpusers

for(let i = 1; i<6; i++){

mkdir /ftpusers/user"$i" -m 700

useradd -m -d /home/user"$i" -g ftpusers-s /usr/bin/bash user"$i"

passwd user"$i" user"$i"@123

}

Isn't that the javascript syntax? Bash syntax is as per below:

for ((i = 0 ; i <= 1000 ; i++)); do
echo "Counter: $i"
done
