Hello all, just thought I'd share my shells script I created to streamline the update process for MSR. Please use this at your own risk.

Here's what you gotta put into your .sh file:

#!/bin/bash

sudo cp -r {path_to_reactor_folder} {path_to_backup_location}-$(date +'%Y_%m_%d_%H:%M')
FILE=$(find {path_to_directory_above_reactor_folder} -maxdepth 1 -type f)
sudo systemctl stop reactor
sleep 5s
cd {path_to_directory_above_reactor_folder}
tar xzvf $FILE
sleep 30s
sudo find {path_to_reactor_folder} -name "package-lock.json" -delete
sleep 10s 
cd {path_to_reactor_filder}
npm run deps
sleep 30s
sudo systemctl restart reactor

The only requirement is that you have drop the updated Reactor .tar.gz file in the directory above your Reactor folder and then run the script. Once that is done run the script you created above (remember to update the paths) and everything should take care of itself. I added the sleep command in a few lines but don't think it's needed.

Edit: I also added in the first line of the script a copy command. This will backup your reactor directory to whatever location you'd like and also name it with the date and time. I have my NAS mounted so that is where reactor gets backed up to. Ideally you'd want to backup your Reactor directly off-site just in case your RPi craps out.

This is very similar to a cheat sheet I keep handy. However, I ran into this:

gzip: stdin: not in gzip format
tar: Child returned status 1
tar: Error is not recoverable: exiting now

@gwp1 Where are you placing the Reactor update tar.gz file?

[toggledbits]

If you use $1 instead of $FILE in the script the path to the Reactor build could just be given on the command line and the script won't have to assume/enforce a location.

@Pabla Folder that contains the reactor folder, ie "folder above".

@gwp1 If your reactor folder is /home/user/documents/reactor your tar.gz file should be in home/user/documents. But thats not what the error is showing, looks like the Reactor update file isn't in .gz compressed format, I know with certain browsers like Safari they will auto decompress downloaded files.
