Get Command-line Arguments

Post Example

Command-line arguments are a common way to parameterize execution of programs.

package main

import (
    "fmt"
    "os"
)

func main() {

    // os.Args provides access to raw command-line arguments.
    // Note that the first value in this slice is the path to the program,
    // and os.Args[1:] holds the arguments to the program.
    argsWithProg := os.Args
    argsWithoutProg := os.Args[1:]

    // You can get individual args with normal indexing.
    arg := os.Args[3]

    fmt.Println(argsWithProg)
    fmt.Println(argsWithoutProg)
    fmt.Println(arg)
}
