SFTP Upload - Synchronize Directory Tree

See more SFTP Examples

Demonstrates how to upload files to synchronize a local directory tree with a remote directory tree. The SyncTreeUpload method recursively descends a local directory tree and uploads files based on existence, last-mod date/time and/or size differences. Tcl

load ./chilkat.dll

set success 0

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

set sftp [new_CkSFtp]

set success [CkSFtp_Connect $sftp "my-ssh-server.com" 22]
if {$success == 1} then {
    set success [CkSFtp_AuthenticatePw $sftp "mySshLogin" "mySshPassword"]
}

if {$success == 1} then {
    set success [CkSFtp_InitializeSftp $sftp]
}

if {$success != 1} then {
    puts [CkSFtp_lastErrorText $sftp]
    delete_CkSFtp $sftp
    exit
}

# Synchronize (by uploading) the local directory tree rooted at "qa_data/sftpUploadTree"
# with the remote directory tree rooted at "syncUploadTest"
# 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.

set remoteDir "syncUploadTest"
set localDir "qa_data/sftpUploadTree"

# Possible modes that can be passed to the SyncTreeUpload method are:
# mode=0: Upload all files
# mode=1: Upload all files that do not exist on the server.
# mode=2: Upload newer or non-existant files.
# mode=3: Upload only newer files. If a file does not already exist on the 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.

# This example will use mode 5 to upload missing, newer, or files with size differences.
set mode 5
# This example turns on recursion to synchronize the entire tree. 
# Recursion can be turned off to synchronize the files of a single directory.
set recursive 1
