I have a program readfile.go
and I want to give the command line argument os.Args[1]
also as readfile.go
.
However \'go run\' thinks
To avoid the ambiguity of getting twice readfile.go
, I advise you to use named flags. This will solve the problem too.
Example:
package main
import (
"flag"
"fmt"
)
func main() {
cmd := flag.String("cmd", "", "")
flag.Parse()
fmt.Printf("my cmd: \"%v\"\n", string(*cmd))
}
Don't forget using flag.Parse()
to retrieve the command line arguments
You can pass args to the go run
command this way: go run .\main.go -cmd main.go
and you'll get as output:
my cmd: "main.go"
I hope this can help other.
