Termux is a command-line terminal emulator app for android built using JAVA language. It is built by Fredrik Fornwall. It has a Linux environment built within it, and it doesn’t require any rooting or separate setup to run the terminal emulator.

Go is a modern programming language built by Google Engineers. Go language is also called “Golang” and it was first released on November 10, 2009. Its syntax is somewhat similar to the C language. It is widely used for writing microservices.

Code:

Go

package main

import "fmt"

// Main function
func main() {

    fmt.Println("Welcome to GeeksforGeeks !!")
}

It will save the Golang hello world program.

Output:

Golang program

Step 4: To compile and run the above program run the following command:

This command will compile the geeks.go program and results in an executable file.

go build geeks.go 

Output:

geeks executable file

The file with green in color is the result of the above command, it is an executable file generated from geeks.go.

Step 5: To run the above program run the following command:

Simply “./” followed by file name to run the Golang program.

 ./geeks

Output:

Successfully compile and run the Golang program in Termux
