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,

If you are using Runtime#exec(), you should try ProcessBuilder instead. — Tadas S

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);
}

+1 For using ProcessBuilder. Note that the code sample doesn't work because \S isn't a valid escape sequence :-)

"c:/source file/test.c" or "c:\\source file\\test.c"

@user93353 c:/source file/test.c

I was not asking a question - i was saying that your original paths won't work - and you can use either of the paths in my comment - both should work.

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
}
