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

$ssh = New-Object Chilkat.Ssh

# Hostname may be an IP address or hostname:
$hostname = "www.some-ssh-server.com"
$port = 22

# Connect to an SSH server:
$success = $ssh.Connect($hostname,$port)
if ($success -ne $true) {
    $($ssh.LastErrorText)
    exit
}

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

# Authenticate using login/password:
$success = $ssh.AuthenticatePw("myLogin","myPassword")

# 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:
$bRecurse = $true
$mode = 2
$success = $scp.SyncTreeUpload($localRoot,$remoteRoot,$mode,$bRecurse)
if ($success -ne $true) {
    $($scp.LastErrorText)
    exit
}

# 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.
