Arguments

You can lookup arguments by calling the Args function on cli.Context, e.g.:

package main

import (
    "fmt"
    "log"
    "os"

    "github.com/urfave/cli/v2"
)

func main() {
    app := &cli.App{
        Action: func(cCtx *cli.Context) error {
            fmt.Printf("Hello %q", cCtx.Args().Get(0))
            return nil
        },
    }

    if err := app.Run(os.Args); err != nil {
        log.Fatal(err)
    }
}
