this does not work for me.

go install github.com/imthaghost/goclone@latest
go: github.com/imthaghost/goclone@latest: module github.com/imthaghost/goclone@latest found (v1.2.0), but does not contain package github.com/imthaghost/goclone

@tmcolby thanks for your feedback, can you please check the following installation command

go install github.com/imthaghost/goclone/cmd/goclone@latest

@mesaglio go version 1.18.1

after running "go install github.com/imthaghost/goclone/cmd/goclone@latest"

getting "goclone: command not found"

@Dodain do you have the golang binary path in your PATH env var?

I tested on docker with you go version and it works.

> docker run -it golang:1.18.1-alpine sh
> /go: go install github.com/imthaghost/goclone/cmd/goclone@latest
. . .
