SCP Sync Tree Upload

See more SCP Examples

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

use chilkat();

$success = 0;

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

$ssh = chilkat::CkSsh->new();

# 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 != 1) {
    print $ssh->lastErrorText() . "\r\n";
    exit;
}

# Wait a max of 5 seconds when reading responses..
$ssh->put_IdleTimeoutMs(5000);

# Authenticate using login/password:
$success = $ssh->AuthenticatePw("myLogin","myPassword");
if ($success != 1) {
    print $ssh->lastErrorText() . "\r\n";
    exit;
}

# Once the SSH object is connected and authenticated, we use it
# in our SCP object.
$scp = chilkat::CkScp->new();

$success = $scp->UseSsh($ssh);
if ($success != 1) {
    print $scp->lastErrorText() . "\r\n";
    exit;
}

# The remoteRoot is relative to the HOME directory of the SSH user account.
$remoteRoot = "workspace/projectB";
$localRoot = "c:/aaworkarea/scp/workspace/projectB";

# 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->put_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->put_SyncMustMatch("*.cpp; *.h");

# Do the recursive sync to upload newer or non-existant files:
$bRecurse = 1;
$mode = 2;
$success = $scp->SyncTreeUpload($localRoot,$remoteRoot,$mode,$bRecurse);
if ($success != 1) {
    print $scp->lastErrorText() . "\r\n";
    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.
print "Files uploaded: " . "\r\n";
print $scp->syncedFiles() . "\r\n";

print "----" . "\r\n";
print "SCP sync upload success." . "\r\n";

# Disconnect
$ssh->Disconnect();
