how to copy ENV variables to another device ?

Thank you @mcraa, this helped.

To read ENV variables, I can use:

balena envs --device <my_device_id>

or for a fleet:

balena envs --fleet <my_fleet_name>

After receiving from one device (or fleet), I was able to write to another device or fleet.

I made two scripts using the Balena CLI:

Script for adding ENV variables to a fleet:

#!/bin/bash
# 
balena env add MY_ENV_KEY1  my_env_value1  --fleet $1
balena env add MY_ENV_KEY2  my_env_value2  --fleet $1
balena env add MY_ENV_KEY3  my_env_value3  --fleet $1
balena env add MY_ENV_KEY4  my_env_value4  --fleet $1

To execute, in a Terminal, type:
bash add_fleet_ENVs.sh <my_fleet_name>

Script for adding ENV variables to a device:

#!/bin/bash
# 
balena env add MY_ENV_KEY1  my_env_value1   --device $1
balena env add MY_ENV_KEY2  my_env_value2   --device $1
balena env add MY_ENV_KEY3  my_env_value3   --device $1
balena env add MY_ENV_KEY4  my_env_value4   --device $1

To execute, in a Terminal, type:
bash add_device_envs.sh <my_device_id>
