I am making a shell script for Android to run on ADB, however, the script should download a file. Commands like wget and curl aren't available in /system/bin. Here are a few possibble solutions that I thought of, each with its cons:

  1. Rooting and installing BusyBox (my target systems are rootless)
  2. Downloading file in computer using wget or curl then transferring the file to Android with adb push (the script should be ran on Android, not the computer connected to it)
  3. Downloading wget or curl in Android (how can I download a binary without them in first place???)
  4. Termux (nope, my script sets some settings in Android which Termux can't)

Is it even possile? If yes, how?

    Why don't you just include an HTTP library in your command-line program and download the file yourself? You are developing a command-line program not a shell script.

    Put your busybox or wget or curl binary in /data/local/tmp/ and execute from there. Simple.

You have two options.

  1. Install Termux, which supports curl.

  2. Use your option number 2. adb push simply copies the file (unlike adb install, which looks for an apk file and tries to install it on the device).

Since you say that you are writing a shell script, you will have to install an Android terminal and (presumably) a Linux environment anyway.

You say "my script sets some settings in Android which Termux can't." If you need root access for an app, you may get what you need using Magisk.
