termux: running termux via adb without *any* direct interaction with the device?
Per the comment by Ifran Latif, above, the following works ...

(1) launch termux

(2) do the following:

echo 'sv up sshd
sshd started' &gt;.profile


(3) run this whenever I want to start sshd via adb:

adb shell am start -n com.termux/.HomeActivity
