Enter in information into terminal with BASH

February 4, 2023

I am working on trying to configure a Python based IoT platform on a Ubuntu 20.04 LTS edge device that requires a lot of redundant steps for entering information into the terminal.

For example I have to run these two commands below inside a Python virtual environment for device address number where I am showing device address number 11 as an example:

(volttron) geb@volttron:~$vctl config store platform.driver registry_configs/11.csv ./registry_configs/11.csv --csv
(volttron) geb@volttron:~$vctl config store platform.driver devices/slipstream_internal/slipstream_hq/11 ./devices/11

And I have all these device addresses to do the same command but switch out the 11 for the correct address:

I’m a first timer in Bash … so I started this journey with: $ nano make_reg_configs.sh

And it looks like this:

#! /bin/bash

echo "vctl config store platform.driver registry_configs/$1.csv ./registry_configs/$1.csv --csv"
echo "vctl config store platform.driver devices/slipstream_internal/slipstream_hq/$1 ./devices/$1"

So at least with this I think I can just do below for each one of my addresses:
bash make_reg_configs.sh "11"

That returns:

vctl config store platform.driver registry_configs/11.csv ./registry_configs/11.csv --csv
vctl config store platform.driver devices/slipstream_internal/slipstream_hq/11 ./devices/11

Where it looks correct with just printing the string with echo but how would I enter the string into the terminal? I think I need something other than echo, would also be cool to just for loop through all the addresses as well if its not a hassle to incorporate that as well. Hopefully this all makes sense!

>Solution :

And if I understood your final goal correctly (combining with the comment from diego)… if you save your addresses to a file called addresses in the same directory as your script this would do them all:

#! /bin/bash
while read address
do
  vctl config store platform.driver "registry_configs/${address}.csv" "./registry_configs/${address}.csv" --csv
  vctl config store platform.driver "devices/slipstream_internal/slipstream_hq/${address}" "./devices/${address}"
done<addresses
