Usage Guide

This guide attempts to describe an typical execution of this script

1. Downloading/Installing the script

To download this script, we'll be using wget, a application present on most bash compatible systems by default

wget https://github.com/reHackable/scripts/raw/master/host/rezone.sh

From here on, you may opt to copy the script to a path defined in the $PATH variable so that it can be executed directly from the terminal

2. Executing the script

Assuming our device is connected to the machine via USB, we can execute the script with no arguments provided. The script will attempt to connect to the device trough SSH.

It is important to note, that the device must remain unlocked until the script has completed

$ bash rezone.sh

3. Selecting the timezone

The script will prompt the user to enter his desired timezone. If left empty, it will be set to the host timezone by default, as seen in parentheses (in the case of this example: CET)

= reZone =
----------
See https://en.wikipedia.org/wiki/List_of_tz_database_time_zones for possible timezones
Set timezone to (CET): 

We will proceed with the default host timezone by simply leaving the input blank

= reZone =
