Running cmd with spaces from java

Question

I want to run a command through java session. The command contains spaces. as "C:\\With Space\\sample.exe" -command_option "C:\\Source File\\test.c" This works if

C:\WithoutSpace\sample.exe -command_option "C:\Source File\test.c"

if we keep the quotes in C:\\With Space\\sample.exe we get error as :'The filename, directory name, or volume label syntax is incorrect.' and if we remove the quotes then the exe do not run... please guide.

Thanks,

Answer 1

Try this:

String[] arg = {"cmd","/c","C:/Source File/test.c"};
ProcessBuilder pb = new ProcessBuilder(arg);
Process pr = pb.start();   

Also, you can use Runtime.exec(String[]) version

Example:

Runtime rt = Runtime.getRuntime();
String[] args = { "cmd", "/c", "C:/Source File/test.c"};
try
{
    Process proc = rt.exec(processCommand);
}

Answer 2

You can try this:

Process process = Runtime.getRuntime().exec("'C:\WithoutSpace\sample.exe' -command_option 'C:\Source File\test.c'");
BufferedReader in = new BufferedReader(new InputStreamReader(process.getInputStream()));

while ((line = in.readLine()) != null) {
    //line contain command output
}
