A free app for Android, by Adam Ioannides.

A shell script is a computer program that is written to be executed by the Unix shell, also known as a command-line interpreter. Scripting languages include the various dialects of shell scripts. Shell scripts typically perform operations such as file manipulation, program execution, and text printing.

A shell script is most beneficial for repetitive tasks that would take too long to execute by typing one line at a time. Shell scripting is not a single language, but because it employs some natural language commands, it is simple to learn even if you have no programming experience. However, each shell scripting dialect is considered a language, and shells require a lot of practice if you plan more complex activities. This is where the SH Script Runner Android app can be helpful.

You can run sh script on your Android device using SH Script Runner. This app lets you load and save scripts, as well as execute them with superuser privileges if root is available.
