Running PuTTY -m in background (no window wanted)

问题

I am running PuTTY from a Perl script using the system command (Windows 7). I use the -m command line option and it works great, but I do not want a window popping up. It's a short lived session, so it is annoying having the window open up for a second to make the connection and then close.

I searched "windows background" "putty background" and many other variations. I got close but no cigar. The thread "Run putty jobs...MATLAB" Was oh so close, but I was already doing that.

You cannot make PuTTY not show its window. See PuTTY wish no-terminal-window.

Though you may use Plink instead. The Plink is a tool from PuTTY suite, with the same functionality and command-line arguments as PuTTY (including the -m). But contrary to PuTTY, it is a console application. So when you run it from your Perl script, it will inherit the Perl console window. It won't open its own.

See Using the command-line connection tool Plink.

Note that the Plink supports specifying a command on its command line, so you can actually avoid using a temporary file for the -m switch:

plink.exe -ssh user@example.com "command"

This is achievable by using a VB script to call plink.exe -batch -load [SessionName].

Assume the command line you need is like this:

plink.exe -batch -load SSHSession

Now you could write a VB script named launchPlink.vbs to check for a running instance of plink.exe and that particular session name. If no process was found then load plink.exe in a hidden window:

Set objWMIService = GetObject("winmgmts:\\.\root\cimv2")
sQuery = "SELECT CommandLine FROM Win32_Process WHERE Name='plink.exe' AND CommandLine LIKE '%-load SSHSession'"
Set objItems = objWMIService.ExecQuery(sQuery)
If objItems.count = 0 Then
    Set objShell = WScript.CreateObject("WScript.Shell")
    intReturn = objShell.Run("plink.exe -batch -load SSHSession", 0, False)
End If

To call the script just use the following line:

wscript.exe launchPlink.vbs

This method can also be used with task scheduler to check and restart the connection if something goes wrong.
