(Ruby) SFTP SyncTreeDownload - Find out what files were downloaded

See more SFTP Examples

Demonstrates how to find out which files were downloaded in a SyncTreeDownload method call.

Chilkat Ruby Downloads install from rubygems.org gem install chilkat or download... Ruby Library for Windows, MacOS, Linux, Alpine Linux

require 'chilkat'

# 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 == true)
    success = sftp.AuthenticatePw("mySshLogin","mySshPassword")
end

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

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

# Synchronize the remote directory tree rooted at "syncDownloadTest/xml"
# with the local directory tree rooted at "qa_output"
# Both directories are relative paths.  The remote directory
# is relative to the HOME directory of the SSH user account.
# The local directory is relative to the current working directory of the process.
# It is also possible to use absolute paths.

remoteDir = "syncDownloadTest"
localDir = "qa_output"

# Possible modes that can be passed to the SyncTreeDownload method 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.
# mode=99: Do not download files, but instead delete remote files that do not exist locally.

# This example will use mode 6 to download missing, newer, or files with size differences.
mode = 6
# This example will turn on recursion to synchronize the entire tree. 
# Recursion can be turned off to synchronize the files of a single directory.
recursive = true
success = sftp.SyncTreeDownload(remoteDir,localDir,mode,recursive)
if (success != true)
    print sftp.lastErrorText() + "\n";
    exit
end

# Examine the list of downloaded files.
# The downloaded files are listed one per line in the SyncedFiles property.
# Local directories that were created will be listed with a trailing "/" char.
fileList = sftp.syncedFiles()
print fileList + "\n";
print "" + "\n";

# For example:

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

# You could load the strings into a Chilkat string table..
sb = Chilkat::CkStringBuilder.new()
sb.Append(fileList)

st = Chilkat::CkStringTable.new()
st.AppendFromSb(sb)

# Find out how many files + dirs
print "Total count = " + st.get_Count().to_s() + "\n";

i = 0
while i < st.get_Count()
    print st.stringAt(i) + "\n";
    i = i + 1
end

print "Success." + "\n";
