I know that Android internally uses Toybox as its basics for Linux sh commands. And in Internet I can read about toybox the help doc. == Presumably since I do not want to have connection to a computer, there is no possibility in Samsung Galaxy S10+, Android 12, to use ADB. Am I right? == Thus, in my smartphone by itself, how can I invoke toybox and use toybox its shell commands. This, please, as a general question. == Now especially, this I want to do while programming a Button in Total Commander. E.g. as a first test, I wrote in the Button "toybox --version". This works. == Then ongoing I want how to use the sh copy command "cp" (exhausting all options). == Then how to use shell variables. In toybox there seems not to exist Parameter Expansion with "$variablename". How is the usage of variables in toybox, thus in Android? I mean general shell variables, beside the parameters defined for the Buttons, e.g. %P, %T, %M, %N, ... == In Internet there is no article about these items. If needfull, I am willing to learn Java, and have already bought a thick book. Is there a intraductory documentation regarding these itens. == For other purposes I use Termux. But Termux has no direct access to the files and variables as I need in in Total Commander Buttons. Thanks, Regards

Have a Chainfire-rooted Samsung Galaxy J5 with Android 7.1. Busybox 1.34.1 in /system/xbin, and Toybox (unfortunately) in /system/bin (installed by: "toybox | toybox sed 's/\ /\n/g'| toybox sed '$d'| while read line; do toybox ln -sf /system/bin/toybox /system/bin/$line; done)". How to move (or delete) them properly? I did it with Total Commander 'search' for 'toybox' string (as it should be in symlinks?) and then move them (just like in Windows). But I think it was bad, as I run into fs problems. Symlinks were not "really" deleted and the "moved" ones were "converted" into files (of same size, ~273k).

I replaced old /system/bin/toybox with a new binary from [http://landley.net/toybox/bin](http://landley.net/toybox/bin) then I created symlinks with for i in $(./toybox); do ln -s toybox $i. There is su in symlinks. Now I cannot open Magisk anymore, stuck at splash screen mask. Also MiXplorer cannot browse root dirs. With Terminal Emulator I can still browse root dirs. If I type which su I get /sbin/su which is a symlink to /sbin/magisk. I have not yet tried to reboot because I fear to get stuck, maybe it would repair by itself but who knows? If I type whoami I get bad uid 0, after su shell I get bad uid 2000 and so on. How can I restore root? I can access TWRP recovery.

In my /system/bin/ I have a executable named toybox, and various other directory entries in that directory symlinked to the toybox, eg basename and [. How do I uninstall toybox? Context: I believe it's messing with advanced root detection of Citi banking (my Revolut app is working just fine with Magisk's SafetyNet Fix)
