Swift Package Manager

Add Shout as a dependency to your Package.swift:

dependencies: [
    .package(url: "", from: "0.5.0")


Creating a session

You create a session by passing a host and optionally a port (default 22):

let ssh = try SSH(host: "")
// or
let ssh = try SSH(host: "", port: 22)


You can authenticate with a private key, a password, or an agent.

Private key

To authenticate with a private key, you must pass the username and the path to the private key. You can also pass the path to the public key (defaults to the private key path + ".pub") and the passphrase encrypting the key (defaults to nil for no passphrase)

session.authenticate(username: "user", privateKey: "~/.ssh/id_rsa")
// or
session.authenticate(username: "user", privateKey: "~/.ssh/id_rsa", publicKey: "~/.ssh/", passphrase: "passphrase")


Simply pass the username and password:

session.authenticate(username: "user", password: "password")


If you've already added the necessary private key to ssh-agent, you can authenticate using the agent:

session.authenticateByAgent(username: "user")

Executing commands

You can remotely execute a command one of two ways. session.execute will print the output of the command to stdout and return the status of the command, while session.capture will not print anything to stdout and will return both the status and the output of the command as a string.

let status = try session.execute("ls -a")
let (status, output) = try session.capture("pwd")

Send files

You can send a local file to a remote path, similar to the scp command line program, with sendFile.

let status = try session.sendFile(localURL: myLocalFile, remotePath: "~/cats.png")


You can open an SFTP session with the remote server:

let sftp = try session.openSftp()
try "/a/remote/file", localURL: myLocalFile)
try sftp.upload(localURL: myLocalFile, remotePath: "~/cats.png")


You can instruct the session to request a pty (pseudo terminal) before executing commands:

session.ptyType = .vanilla
