Hey!
.sh is a unix shell script file...!

What is a shell script?

A shell script is a script written for the shell, or command line interpreter, of an operating system. It is often considered a simple domain-specific programming language. Typical operations performed by shell scripts include file manipulation, program execution, and printing text.

Many shell script interpreters double as command line interface, such as the various Unix shells, Windows PowerShell or the MS-DOS COMMAND.COM. Others, such as AppleScript or the graphical Windows Script Host (WScript.exe), add scripting capability to computing environments without requiring a command line interface. Other examples of programming languages primarily intended for shell scripting include DCL and JCL

Hey!
Yup there are some softwares developer that develop software in shell scripts... Anyways, You need execute rights and the file needs to be executable. You need to type this in the terminal to make the file executable:

chmod +x filename

or even

sudo chmod +x filename

Then navigate to the directory and run it by typing this:

./filename

-OR-

sh filename.sh

use "sudo" command as prefix if it doesn't work...!
All the best...!
