I have often hated the idea of looking for apps among tons of glossy icons and running them that way. I wonder if there is a terminal capability in Android like that of Linux or Windows (Run window) for faster and more seasoned app access. Is such a thing in Android inherently?
Yep there is this
You can use the following command to run apps
am start -a android.intent.action.MAIN -n package/class_fullname
I recommend using Termux. You can find it on Play Store. I find it better than Terminal Emulator because it has a rich repository from which you can download a lot of useful programs. I had no idea what Bash Script, Unix, Linux commands were or how to use them. After playing with Termux for 1-2 years (in my own rithm and just with stuff I want curious about plus experimenting), I saw some advanced bash scripting videos on YouTube and I was like : Hey I knew that! Thank you Termux :) Mainly you need root for a lot of the things (playing with system files), but you can do a lot of other things as well, without it. Finding duplicate files, listening to online radio, downloading videos, you can even play some text based games :) If you know terminal commands well (linux, unix, Android) you will soon discover that you know a bit of coding as well :D
