问题 I use a CLI program regularly which is accessed through a docker container. Once I enter the container, I can start using my CLI program in question. The issue I'm having is I want to continue to interact with the same command line instance. Basically I'm trying to create a GUI program that will run "on top" of a CLI program. I just don't know how to keep sending commands to the same CLI instance: List<String> command = new ArrayList<String>(); command.add("cmd.exe" ); command.add("/c");

问题 I’m trying to run an external program with arguments. The program can take different types of arguments, for instance avl tip.avl or avl < test.ops I can get avl tip.avl running through try { String[] list = {"avl", "test_0.avl"}; ProcessBuilder pb = new ProcessBuilder(list); pb.command(list); final Process p = pb.start(); BufferedReader br = new BufferedReader( new InputStreamReader( p.getInputStream() ) ); String line; while ((line = br.readLine()) != null) { System.out.println(line); } }

问题 I've been using ProcessBuilder to successfully invoke a process with various environment variables using env.put("VAR","value") . Now I'd like to source some bash scripts to set a whole bunch of environment variables that are not predetermined within java. Anyone know of an easy way to do this? 回答1: bash supports the environment variable BASH_ENV on startup. Set the variable to your script and its contents will be sourced before execution. See bash(1) for details. 回答2: If your "batch scripts"

问题 Is it possible to use ProcessBuilder with GWT? When I declare an instance of a new ProcessBuilder, I get: java.lang.ProcessBuilder is not supported by Google App Engine's Java runtime environment 回答1: Your question is about GWT supporting ProcessBuilder, but the error you get is from Google App Engine and not GWT related.

问题 I am currently trying to see if I can run a program shortcut in windows (.lnk) file, from powershell, within Java. I know there are better tools to use, and that I should just interact directly with the .exe, but please humor me, this is for testing purposes. So essentially, I need to run the .lnk file, via powershell from java. The main predicament I am currently having is that the command which should work from within powershell "start \"C:/Adobe Reader X.lnk\"" In the IDE this will run
