I'm having a bit of trouble running it. I have installed mscp and set passwd but it doesn't seem to work. Any possible solution?

So you have Termux on the phone, OpenSSH installed, password set, and granted storage? termux-setup-storage

Not sure why the adb invocation is producing the unexpected token.

After verifying everything above post your output for

bash -x ./betteradbcopy pull /sdcard/

So we can get an idea of what is being built out as it's running.

Termux on phone, openssh installed, password set and termux-setup-storage has been run

I guess it doesn't expect to be ran on WSL2 but I don't understand why permission is denied. I tried passwd only and passwd parker. I'm also connecting adb using WiFi.

You need to escape the path in the adb command. Mine was pulling in the computer path as well, but because it was all Unix, it didn't mess with it.

files/usr/bin/bash -lic 'export PATH=/data/data/com.termux/files/usr/bin:"$PATH"; export

It's either double or single quotes I don't recall exactly.

Worst comes to worse. I guess it's not really needed since mine was all garbage too.

files/usr/bin/bash -lic 'export PATH=/data/data/com.termux/files/usr/bin; export

That solved one problem but stat: /sdcard/ Permission denied is still an issue.

And you can list the SD card within termux directly?

Only thing I can think of is maybe try removing the trailing forward slash.

pull /sdcard

I can cd into sdcard and make it show the files. I tried what you suggested and it's just the same.

Ok this must be something new with Android 14. I'm seeing the same error here. I can list in Termux but not over the adb shell termux wrapper or SSH.

I'll let you know if I get it working.

In the meantime, the proper fix for path is \ escaping the $

adb shell -t "run-as com.termux files/usr/bin/bash -lic 'export PATH=/data/data/com.termux/files/usr/bin:\$PATH; export LD_PRELOAD=/data/data/com.termux/files/usr/lib/libtermux-exec.so; bash'"```
