Dropbox-Uploader: how to synchronize a folder with cron job?

[MajorC]

Hi,

I would like to synchronize a Dropbox folder with pictures to my RPI, so I can use the pictures as MM background.

I used https://github.com/andreafabrizi/Dropbox-Uploader

Within some time, I managed to download one file to the default folder from my dropbox to the RPI. But I have no idea how to do this as a cron job once an hour.

Any help is highly appreciated.

Thanks

@MajorC why dont you regularly download the whole folder and select files from that to show as background.
I assume with the Download Option of the script you might be able to kind of synchronise your folder.

@lavolp3 I am able to download the folder. But I would like to have a script to do that every time the pi starts up automatically. That’s where I am having the problem at the moment.

@MajorC which part of the ‘when the pi boots’ are u having trouble with

if you use pm2, you can start your script with pm2

pm2 start scriptpath
pm2 save

[MajorC]

@sdetweil can you give me a little bit more details? I am quite new to the MM-world and have no idea where I can find what you wrote?!?

[sdetweil]

@MajorC YOU have to enter those commands

you said you have a script that will download files

now, turn it into something that happens every hour, add a while loop around it…
(I know you don’t know, so google searching will teach you a ton)

then, once THAT works, you can use the pm2 process manager to launch it for you

[sdetweil]

@MajorC you said
But I would like to have a script to do that every time the pi starts up automatically

so, what commands would you issue to do that

creating a script is as simple as writing a file with this commands
making it executable (see chmod command)
and then launching it.

[MajorC]

@sdetweil the script is running fine if I start it manualy by hand.

I need a hint how to do it the same way, the MagicMirror starts.

[sdetweil]

@MajorC i wrote the two commands u need to issue

pm2 start scriptpath (where is your script and what is its name, = scriptpath)
pm2 save

to set it up if you use pm2 to launch MM (which my install script does for you if you used it)

[MajorC]

@sdetweil thank you. It seams to work. The script was way more easy than expected.

May I ask, if I roboot the MM with Strg+Q, will my script run again?
