Runtime.getRuntime().exec()

java, runtime.exec

Solution

Are you familiar with the `exec` double-quotes bug? (for `Runtime.exec` or `ProcessBuilder`)

You can try:

Runtime.getRuntime().exec(new String[] {
  "\"C:/Program Files/MySQL/MySQL Server 5.0/bin/mysqldump\"", 
  "-h", 
  hostName+user+databaseName});

Just make sure none of your parameters you will have to pass contains double quotes (while not beginning with double quotes) (see bug 6511002)

Any parameter like:

mykey="my value with space"

would be changed internally (by the `getRuntime()` implementation) into

"mykey="myvalue with space""

If that is the case, you would need to tokenize the argument:

{"mykey=\"my\"" , "\"value with space\""}

Problem

I can not read a file only when database name contains like (new database (myid) etc. I give a following example code: ``` dumpCommand = "C:/Program Files/MySQL/MySQL Server 5.0/bin/mysqldump -h"+hostName+user+databaseName; Runtime rt = Runtime.getRuntime(); Process proc = rt.exec(dumpCommand); InputStream in = proc.getInputStream(); BufferedReader br=new BufferedReader(new InputStreamReader(in)); String line =null; while((line=br.readLine())!=null) { //able to read line only when database name like abc,datastore etc... System.out.println(line); } ``` Suppose my database name de mo means when I print line I got database name like de only. Is possible when database name with empty space?
