📄 Usage

Run a command via ssh:

package main

import (
	"log"
	"fmt"
	"github.com/melbahja/goph"
)

func main() {

	// Start new ssh connection with private key.
	auth, err := goph.Key("/home/mohamed/.ssh/id_rsa", "")
	if err != nil {
		log.Fatal(err)
	}

	client, err := goph.New("root", "192.1.1.3", auth)
	if err != nil {
		log.Fatal(err)
	}

	// Defer closing the network connection.
	defer client.Close()

	// Execute your command.
	out, err := client.Run("ls /tmp/")

	if err != nil {
		log.Fatal(err)
	}

	// Get your output as []byte.
	fmt.Println(string(out))
}

🔐 Start Connection With Protected Private Key:

auth, err := goph.Key("/home/mohamed/.ssh/id_rsa", "you_passphrase_here")
if err != nil {
	// handle error
}

client, err := goph.New("root", "192.1.1.3", auth)

🔑 Start Connection With Password:

client, err := goph.New("root", "192.1.1.3", goph.Password("you_password_here"))

☛ Start Connection With SSH Agent (Unix systems only):

auth, err := goph.UseAgent()
if err != nil {
	// handle error
}

client, err := goph.New("root", "192.1.1.3", auth)

⤴️ Upload Local File to Remote:

err := client.Upload("/path/to/local/file", "/path/to/remote/file")

⤵️ Download Remote File to Local:

err := client.Download("/path/to/remote/file", "/path/to/local/file")

☛ Execute Bash Commands:

out, err := client.Run("bash -c 'printenv'")

☛ Execute Bash Command with timeout:

context, cancel := context.WithTimeout(ctx, time.Second)
defer cancel()
// will send SIGINT and return error after 1 second
out, err := client.RunContext(ctx, "sleep 5")

☛ Execute Bash Command With Env Variables:

out, err := client.Run(`env MYVAR="MY VALUE" bash -c 'echo $MYVAR;'`)

🥪 Using Goph Cmd:

Goph.Cmd struct is like the Go standard os/exec.Cmd.

// Get new `Goph.Cmd`
cmd, err := client.Command("ls", "-alh", "/tmp")

// or with context:
// cmd, err := client.CommandContext(ctx, "ls", "-alh", "/tmp")

if err != nil {
	// handle the error!
}

// You can set env vars, but the server must be configured to `AcceptEnv line`.
cmd.Env = []string{"MY_VAR=MYVALUE"}

// Run you command.
err = cmd.Run()

🗒️ Just like os/exec.Cmd you can run CombinedOutput, Output, Start, Wait, and ssh.Session methods like Signal...

📂 File System Operations Via SFTP:

You can easily get a SFTP client from Goph client:

sftp, err := client.NewSftp()

if err != nil {
	// handle the error!
}

file, err := sftp.Create("/tmp/remote_file")

file.Write([]byte(`Hello world`))
file.Close()

🗒️ For more file operations see SFTP Docs.
