java - IOexception while runing bash commands through ProcessBuilder -

  
 
 
 I am getting IOException when using a CAD command through a processbilder Trying:  
  Error: java.io.IOException: The program can not be run "sed -i '/ hello world // g' / home / user / test": Error = 2, such a file or directory is not   
 command is  sed -i 's / hello world // g' / home / user / test  but problem There is no command, I can run the command through the terminal only this string "Hello World" will remove  
  throws a public zero extracted string (string string, string file) IOException {String command = "sed -i \ 's /" + str + "// g \" "+ File; println (command); processbiller pb = new process builder (process); process p = pb.start ();}   
 what is the process of being unable to find the file?   
 
 
  process builder  In the constructor try to run it like this: / P> 
  Rosesbilder PB = new Prosesbilder ( "sed", "-i", "s / hello world // g", "/ home / user / test");   
 (You can pass  list & lt; string & gt;  if you wish)  
 To prevent this security vulnerabilities Works like this for. / P>
