I'm trying to add a watcher for a folder, once file is created, start a program
$script= "C:\test.py"
$watcher.Path ="e:\my folder\test folder\dropbox"
Start-Process cmd -Argument "/k python $script $path"
Problem is that, this will always get me error saying e:\my no such file
I know this is an issue with space, but I tried the following, still get same error
Start-Process cmd -Argument "/k python $script '$path'"
does anyone know how to fix this?
many thanks
You need to use escaped embedded double quotes with Start-Process:
$script= "C:\test.py"
$path = "e:\my folder\test folder\dropbox"
Start-Process cmd -Argument "/k python $script `"$path`""
Without that, the spaces in the $path value break the path into multiple arguments when cmd receives the arguments.
`" embeds a verbatim " inside a "..." string.
As an aside:
If your intent is to run a command asynchronously, in a new window (on Windows), as your command suggests, Start-Process is indeed the right tool.
By contrast, do not use Start-Process if you want to run other console applications (such as cmd) synchronously, in the same window; in that event, just invoke the console application directly - see this answer for more.
I was trying to run a powershell cmd to parse the input, specifically to get the version of chrome running on the server.
String version = null;
String command = "powershell.exe (Get-Item \"C:\\Program Files (x86)\\Google\\Chrome\\Application\\chrome.exe\").VersionInfo";
Process process = Runtime.getRuntime().exec(command);
process.getOutputStream().close();
BufferedReader reader = new BufferedReader(new InputStreamReader(process.getInputStream()));
String line = reader.readLine();
while(line!=null){
if(line.matches("[0-9]{2,3}\\.[0-9]{1,2}\\..*")){
version = line.substring(0, line.indexOf("."));
}
line = reader.readLine();
}
This failed with the error indicating that the command was split at the spaces in the path.
I replaced the escaped double quotes with single quotes and it worked:
String command = "powershell.exe (Get-Item 'C:\\Program Files (x86)\\Google\\Chrome\\Application\\chrome.exe').VersionInfo";
