SFTP Sync Download Tree w/ Must-Match Filename Constraints

See more SFTP Examples

Demonstrates how synchronize a directory tree in the download direction, but only download files matching a set of wildcard filenames.

Note: This example requires Chilkat v9.5.0.76 or greater.

Perl

use chilkat();

$success = 0;

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

$sftp = chilkat::CkSFtp->new();

$success = $sftp->Connect("my-ssh-server.com",22);
if ($success == 1) {
    $success = $sftp->AuthenticatePw("mySshLogin","mySshPassword");
}

if ($success == 1) {
    $success = $sftp->InitializeSftp();
}

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

# Possible synchronization modes are:
# mode=0: Download all files
# mode=1: Download all files that do not exist on the local filesystem.
# mode=2: Download newer or non-existant files.
# mode=3: Download only newer files. If a file does not already exist on the local filesystem, it is not downloaded from the server.
# mode=5: Download only missing files or files with size differences.
# mode=6: Same as mode 5, but also download newer files.

# This example will download all files, but only those files having filenames
# that match *.gif and *.eml

# Imagine our remote directory tree has these files and directories:

# 	accentedLatin1.txt
# 	accentedUtf8.txt
# 	alice.key
# 	anter_cert.pem
# 	chiliPepper.gif
# 	helloWorld.pdf
# 	abc/chiliPepper.gif
# 	abc/ghk/
# 	data/chiliPepper.gif
# 	data/xyz/dkimHtmlBody.txt
# 	data/xyz/dkimVerifyTest.eml
# 	data/xyz/emailForCreateDsn.eml
# 	text/frenchUtf8.txt
# 	text/helloWorld.txt
# 	text/PolishEmailBody.txt
# 	text/something/

# Indicate that we only want to create auto-create local directories (if needed)
# for the files that are actually downloaded.  If SyncCreateAllLocalDirs remains
# 1, then the corresponding local directory is created for each remote directory
# traversed regardless of whether files within are downloaded.
$sftp->put_SyncCreateAllLocalDirs(0);

$sftp->put_SyncMustMatch("*.eml; *.gif");

$remoteDir = "syncDownloadTest/someDir";
$localDir = "qa_output";
$mode = 0;
$recursive = 1;
$success = $sftp->SyncTreeDownload($remoteDir,$localDir,$mode,$recursive);
if ($success != 1) {
    print $sftp->lastErrorText() . "\r\n";
    exit;
}

# The following files were downloaded:

# chiliPepper.gif
# abc/chiliPepper.gif
# data/chiliPepper.gif
# data/xyz/dkimVerifyTest.eml
# data/xyz/emailForCreateDsn.eml

print "Success." . "\r\n";
