Automate removal of rogue directories generated by Nvidia Shield TV (Android) on Linux shares.


Hi there,

My name is Alex, and this is my first post. I'm going to try to keep this short. Android is incredibly difficult to control, and I'm sure someone out there knows what I'm talking about when I say it spreads it's seed (Android directories) to everything it touches.

I'm using LibreELEC 8.0.1, and I can easily access the CLI via SSH from my Mac's Terminal. LibreELEC and Kodi forum posts keep racking up views, but either nobody cares to answer, or nobody in those communities knows.

Both B and C are currently active, with no improvement. These are commands I found online - I'm a noob with enough
logic to be able to deconstruct a command and its parameters at least somewhat.

What should I be doing?
A) Somehow making Android stop generating these directories? (Customization on Android TVs seems nearly impossible.)
B) edit samba.conf, add the lines below to each preconfigured share
veto files = /Android/
delete veto files = yes
C) cron job - command works manually, but not via cron daemon (see screenshot)

root seems to have a cron.
you stuck this find command into it? or a script (something you ALLOWED)?

maybe use full paths.
Code:
/usr/bin/find
/usr/bin/xargs
?

Thanks for your reply, Habitual.

I'm not sure - other than this, I'm running LibreELEC with mostly default settings.

In the LibreELEC settings (simply an additional GUI menu amongst the standard Kodi menus, there is an option for cron to be turned on or off. Of course I have it turned on.)

At the command line, I
Code:
crontab -e
and the resulting document was blank. I typed in the command you see in the screenshot, which I had already verified worked at the command line (which is also demonstrated in the screenshot), saved the crontab file, and from the looks of it, it's running the manually validated command every 10 minutes, yet these directories are still present, even when the Android device is off.

Also when I manually run the command, I can see the an Android folder disappear in Finder on my Mac. But I never see it disappear if I leave a Finder window open and wait on the cron job.

Again, this is all new to me; if there's something else to know about the cron function that I'm missing, please let me know.

When you say root seems to have a cron - does that mean I should be doing this elsewhere? I typed cd / before crontab -e. Should I be at a user prompt?

Thanks for your reply!

I've gotta run, but I'll try that when I get home in a few hours and report back.

I figured it out. I added cd / before and cd ~ after the find & xargs commands, and since it was properly running from root that way, it solved the problem!

Code:
*/10 * * * * cd /;find . -maxdepth 5 -type d -name "Android" -print0 | xargs -0 rm -rf;cd ~
Does that make sense? I'm not finding any more Android folders, so I think I'm doing it right.

;cd ~
what purpose does that serve?
and instead of
cd /;find .
you could also use
find /

are you sure it works without giving the full path, i.e. /bin/find or /usr/bin/find?

It probably serves no purpose, based on your question. With very little experience in Linux, I took the "put things back the way they were" approach.

It definitely works, because the Nvidia Shield TV generated those Android folders constantly, and they are nowhere to be seen now.

Thanks for the info; more info on command structure is always be useful.

LOL. Hey, it's a good habit whether in day to day life or behind the keyboard. (And especially I suppose when those two scenarios are one and the same.)
