Termux

Termux combines powerful terminal emulation with an extensive Linux package collection.

1. Enjoy the bash and zsh shells.
2. Edit files with nano and vim.
3. Access servers over ssh.
4. Compile code with gcc and clang.
5. Use the python console as a pocket calculator.
6. Check out projects with git and subversion.

At first start a small base system is downloaded - desired packages can then be installed using the apt package manager known from the Debian and Ubuntu Linux distributions. Access the built-in help by long-pressing anywhere on the terminal and selecting the Help menu option to learn more.
