Question

I have file named with A.txt, Using batch command to copy the file to SFTP Server. After copying the A.txt, to copy the A.txt again to SFTP on same path.There is no possible same name with two files on same path, I want to rename the second copied file like A2.txt.

How to use the 'New name' command in WinSCP command line?

I copying the multiple files with file extension (*.txt), only I want to rename the file which already exist with same name in SFTP Server.

Answer 1

The "New name" command in WinSCP GUI cannot automatically rename uploaded file not to conflict with existing files.

Neither there's such a function in WinSCP scripting.

Though you can code this using WinSCP .NET assembly, for example using PowerShell script:

try
{
    # Load WinSCP .NET assembly
    Add-Type -Path "WinSCPnet.dll"

    # Setup session options
    $sessionOptions = New-Object WinSCP.SessionOptions

    # Setup session options
    $sessionOptions = New-Object WinSCP.SessionOptions
    $sessionOptions.Protocol = [WinSCP.Protocol]::Sftp
    $sessionOptions.HostName = "example.com"
    $sessionOptions.UserName = "username"
    $sessionOptions.Password = "password"
    $sessionOptions.SshHostKeyFingerprint = "ssh-rsa 2048 xxxxxxxxxxx...="

    $localPath = "c:\local\path\*.txt"
    $remotePath = "/remote/path/"

    try
    {
        # Connect
        Write-Host "Connecting..."
        $session = New-Object WinSCP.Session
        $session.SessionLogPath = "session.log"
        $session.Open($sessionOptions)

        # Upload files
        Write-Host "Uploading..."

        $localFiles = Get-ChildItem -Path $localPath

        foreach ($localFile in $localFiles)
        {
            $name = $localFile.Name;
            Write-Host "Found file $name"

            $index = 0;
            while ($session.FileExists($remotePath + $name))
            {
                Write-Host "$name exists already in remote directory"
                $index++;
                $name = $localFile.Name + " ($index)"
            }

            Write-Host "Uploading as $name ..."
            $session.PutFiles($localFile, $remotePath + $name).Check()
        }

        Write-Host "Done"
    }
    finally
    {
        # Disconnect, clean up
        $session.Dispose()
    }

    exit 0
}
catch [Exception]
{
    Write-Host $_.Exception.Message
    exit 1
}
