cp
Package cp is a tiny utility. It exposes a type that can easily copy one file directory into another, somewhat analogous to the cp unix command.
In natural Go fashion the files are copied concurrently to maximise throughput.
The Copier can be used as-is.
You can plugin any file system you want using the github.com/spf13/afero.Fs interface. The OS filesystem object is the default.
Usage
func main() {
args := os.Args[1:]
if len(args) < 2 {
oops("not enough arguments\n")
}
from, to := args[0], args[1]
copier := cp.Copier{
Clobber: true,
}
if err := copier.Copy(from, to); err != nil {
fatal("copying files: %v\n", err)
}
}
