help testing batch / bash file command on chromebook

[RoundTwo]

I am trying to replicate a command I made for windows 10 as a batchfile. I want to replicate the command for someone I know which uses a chromebook. I just want to know if this works before sending it:

#!/bin/bash

exec 1>/dev/null
exec 2>/dev/null

/path/to/browser 'any website url'
/path/to/browser 'any website url'
/path/to/browser 'any website url'
/path/to/browser 'any website url'
/path/to/browser 'any website url'
/path/to/browser 'any website url'

Here is the windows version if at all relevant:

@echo off

start "name" "url"

start "name" " url"

start "name" "url"

start "name" "url"

start "name" "url"

start "name" "url"

If it works correctly it should open one browser window with a few tabs all at once. Any help?
