How gosh Works

Currently, the gosh folder contains all .go files. gosh.go contains the main function, which is used to accept instructions and call the appropriate <command>.go file.

Naming Conventions

gosh uses the standard Go naming conventions. Each supported command is contained in an appropriately named .go file. For example, the command mkdir is implemented in the mkdir.go file.
All exported commands should be capitalized and commented appropriately.

Each .go file that contains executable code will have the package main declaration at the top of the file.

Example .go File

package main

import (
	"fmt"
)

// NamePrinter This function prints a name.
func  NamePrinter() {
	name := "Frank Sinatra"
	fmt.Printf("Hello, %s.\n", name)
}

The function NamePrinter will be visible and usable in other .go files in the folder without having to import anything.

Building gosh

If you are building gosh for the first time, download the following prerequisite package using the command line:

go get github.com/buger/goterm

Build gosh from the gosh folder with go build . The result will be an executable called gosh.exe .

Running gosh

Windows: Run gosh with ./gosh.exe

Linux: Run gosh with ./gosh
