SFTP Sync Download Tree w/ Must-Match Directory Constraints

See more SFTP Examples

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

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

Ruby

require 'chilkat'

success = false

sftp = Chilkat::CkSFtp.new()

success = sftp.Connect("my-ssh-server.com",22)
if (success == true)
    success = sftp.AuthenticatePw("mySshLogin","mySshPassword")
end

if (success == true)
    success = sftp.InitializeSftp()
end

if (success != true)
    print sftp.lastErrorText() + "\n";
    exit
end

# 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.

# Only enter remote directories named either "data" or matching "x*"
sftp.put_SyncMustMatchDir("data; x*")

# 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/

remoteDir = "syncDownloadTest/someDir"
localDir = "qa_output"
mode = 0
recursive = true
success = sftp.SyncTreeDownload(remoteDir,localDir,mode,recursive)
if (success != true)
    print sftp.lastErrorText() + "\n";
    exit
end

# The following files were downloaded:

# accentedLatin1.txt
# accentedUtf8.txt
# alice.key
# anter_cert.pem
# chiliPepper.gif
# helloWorld.pdf
# data/chiliPepper.gif
# data/xyz/dkimHtmlBody.txt
# data/xyz/dkimVerifyTest.eml
# data/xyz/emailForCreateDsn.eml

print "Success." + "\n";
