Auto-upload of a file via FTP on its change

Question

FTP

Are there programs that allow you to monitor files and automatically upload them to the server if they have changed? Everything I've found on the internet doesn't do it properly.

Answer 1

On Linux, there is inotify, which can be used to implement this in a couple of lines. and, it seems, there are interfaces to this either, in the form of system utilities. on Windows, probably, these are some kind of hooks

Answer 2

On PowerShell (default on Win 7), it's something like this ( scrape in the bottom of the barrel and stupidly in the forehead , so it's better to test :) ):
We use two dotnet classes - System.IO.FileSystemWatcher and System.Net.WebClient.
Subscribe to acc. FS events, we get the file name from the event details and upload it using WebClient. The WebClient is smart and can be easily converted to SFTP later.

#
# Watch for files in $watchDir that a match a filer $watchFilter
#    and upload them to FTP $ftpUrl when they are changed (modified)
#

$ftpUrl = "ftp://username:[email protected]/pub/incoming/"
$watchDir = "b:\temp"
$watchFilter = "*.txt"

function uploadFile($fullFileName)
{
    $webclient = New-Object System.Net.WebClient
    $fileName = [system.io.path]::GetFileName($fullFileName)
    $fileUrl = $ftpUrl+$fileName
    $uri = New-Object System.Uri($fileUrl)
    try
    {
        $rc = $webclient.UploadFile($uri, $fullFileName)
    }
    catch [System.Net.WebException]
    {
        Write-Host "[ERR]: "$_
        return
    }
  Write-Host "Uploaded $fullFileName"
}

$watcher = New-object System.IO.FileSystemWatcher $watchDir
$watcher.EnableRaisingEvents = $true
$watcher.Filter = $watchFilter

$changed = Register-ObjectEvent $watcher "Changed"  -Action {
    Write-Host $eventArgs.ChangeType, $eventArgs.Fullpath
    uploadFile $eventArgs.Fullpath
}

while($true) {
    echo "."
    start-sleep -s 5
}

# EOF

nnCron + scripts (cmd/python/autoit/...) + console ftp client
