How to execute Bash commands and collect output from Java?

Hello everyone, basically I am writing the main console application and would like to be able to run commands from it, such as sudo ***, halt, ifconfig, etc.

Any insight ?.

Answer 1

You can use the processBuilder API for this purpose. See this example .

Answer 2

unverified code:

Runtime run = Runtime.getRuntime(); Process pr = run.exec(bashcommand); pr.waitFor(); BufferedReader buf = new BufferedReader(new InputStreamReader(pr.getInputStream())); while ( ( String line ; line = buf.readLine() ) != null ) { System.out.println(line); }
