SCP Sync Tree Upload

See more SCP Examples

Synchronize local and remote directory trees by uploading newer or missing files to the remote server. Swift

    var success: Bool = false

    // This example requires the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    let ssh = CkoSsh()!

    // Hostname may be an IP address or hostname:
    var hostname: String? = "www.some-ssh-server.com"
    var port: Int = 22

    // Connect to an SSH server:
    success = ssh.connect(hostname: hostname, port: port)
    if success != true {
        print("\(ssh.lastErrorText!)")
        return
    }

    // Wait a max of 5 seconds when reading responses..

    // Authenticate using login/password:
    success = ssh.authenticatePw(login: "myLogin", password: "myPassword")
    if success != true {
        print("\(ssh.lastErrorText!)")
        return

    // Once the SSH object is connected and authenticated, we use it
    // in our SCP object.

    // Upload synchronization modes:
    // mode=0: Upload all files
    // mode=1: Upload all files that do not exist on the FTP server.
    // mode=2: Upload newer or non-existant files.
    // mode=3: Upload only newer files.  If a file does not already exist on the FTP server, it is not uploaded.
    // mode=4: transfer missing files or files with size differences.
    // mode=5: same as mode 4, but also newer files.

    // Additional files and directores can be excluded by setting the SyncMustNotMatch property.
    // The SyncMustNotMatch patterns apply only to the final filename or directory part of a path.
    // If a directory matches, then it will not be traversed in a recursive traversal.
    // 
    scp.syncMustNotMatch = "*.o;*.obj;*.log; temp"

    // The SyncMustMatch property can be set to restrict the files uploaded to only those
    // matching at least one pattern in a set.
    scp.syncMustMatch = "*.cpp; *.h"

    // Do the recursive sync to upload newer or non-existant files:
    var bRecurse: Bool = true
    var mode: Int = 2
    success = scp.syncTreeUpload(localBaseDir: localRoot, remoteBaseDir: remoteRoot, mode: mode, bRecurse: bRecurse)
    if success != true {
        print("\(scp.lastErrorText!)")
        return
    }

    // The files actually uploaded can be examined in the SyncedFiles property.
    // It is a string property that contains the relative path, one per line, of each
    // file uploaded.
    print("Files uploaded: ")
    print("\(scp.syncedFiles!)")

    print("----")
    print("SCP sync upload success.")

    // Disconnect
    ssh.disconnect()
