go-cp

Golang library to make copying files easy

Copying a file in vanilla Go forces you to deal with filesystem I/O, it's a bit overcomplicated for the general case, when you just want to copy a file as easy as using cp $source $dest. This tiny, one-use-case library is just for that.

Installation

Run go get github.com/n-marshall/go-cp.

Try it

In the repo folder run make example.

Usage

Simply use cp.Copy(sourceFile, destinationFile).
Full documentation found here

Example

package main

import (
	"log"

	cp "github.com/nmrshll/go-cp"
)

func main() {
	err := cp.CopyFile("examples/examplefile.ext", "examples/examplefile.copy.ext")
	if err != nil {
		log.Fatal(err)
	}
}

Usage details

CopyFile() copies a file from src to dst. If src and dst files exist, and are the same, then return success. Otherwise, attempt to create a hard link between the two files. If that fails, copy the file contents from src to dst.
Creates any missing directories.
Supports '~' notation for $HOME directory of the current user.

AbsolutePath() converts a path (relative or absolute) into an absolute one.
Supports '~' notation for $HOME directory of the current user.
