command line language for Android tablet (wget equivalent) I am a Linux enthusiast and probable expert, and using it since 1993 on the command line (today with zsh) (and Unix since 1987, SunOS3.2).

I personally have a Huawei tablet, details here. With an SD card.

I also have a Logitech Bluetooth keyboard case for that tablet.

I need to be able to read some PDF documents on the tablet without a working internet connection. (at my work at CEA/LIST - a quite bureaucratic organization since indirectly related to French nuclear warheads, I have a powerful Dell workstation with root access &amp; Ethernet connection to the Internet under Debian/Unstable - so sometimes Xorg does not work properly -, but no access to the corporate Wifi; for the clips-rule-gcc project I prefer to read the CLIPS documentation on my BYOD tablet).

If my tablet was good genuine Linux Debian system, I would just wget http://clipsrules.sourceforge.net/documentation/v640/bpg.pdf when Internet is available, and later evince bpg.pdf when it is not, taking advantage of zsh auto completion facilities.

What are the equivalent on Android 8 ?

My AppStore is google, and I was not yet able to root my tablet. Dreaming of that every day.
Did you tried Termux?
The terminal emulator for android, this does not require any root access either.



Edit: to install wget type pkg install wget and press enter.

For pdf viewer use native android one such as Mu Pdf or, Google pdf viewer

Once installed you can try xdg-open filename.pdf
It will give you a list of the compatible app to open the file or else you can open the pdf viewer app to browse files of your choice.
