Which app should i use to write an unix script on phone?

Question

I want to practice Unix scripts for my exams & I don't have access to a computer. Can anyone please help me find a way to do it via phone?

Answer 1

If you are using Android, Termux is essentially a Linux terminal for your phone which allows you to do almost anything you would be able to do on a computer running Linux.

Answer 2

Termux is good as Faisal said. But it has some limitations as compared to Linux running on a computer. Try installing userland and connect Bot apps. It offers you to use different Linux distributions with full access as it does on Linux running on a computer.
