我正在嘗試設置我的java程序運行的ulimit。目前，似乎ulimit -n設置為4096，因為當我運行此代碼（這是我的java程序的一部分）時，它輸出4096。ProcessBuilder processBuilder = new ProcessBuilder("/bin/bash", "-c", "ulimit -n");try {  Process process = processBuilder.start();  // Prints 4096.  LOGGER_.info(getStringFromInputStream(process.getInputStream()));} catch (IOException e) {  // The flow does not reach this catch block.  LOGGER_.error("exception caught: " + e.getMessage());}是否可以將其更改為其他內容，例如8192？我試過這個：ProcessBuilder processBuilder2 = new ProcessBuilder("/bin/bash", "-c", "ulimit -n 8192");try {  Process process = processBuilder2.start();  LOGGER_.error("starting agent2...");  LOGGER_.error(getStringFromInputStream(process.getInputStream()));} catch (IOException e) {  LOGGER_.error("exception caught2: " + e.getMessage());}和try {  String[] cmdString = new String[3];  cmdString[0] = "/bin/bash";  cmdString[1] = "-c";  cmdString[2] = "ulimit -n 8192";  Process process = Runtime.getRuntime().exec(cmdString);  LOGGER_.error(getStringFromInputStream(process.getInputStream()));} catch (IOException e) {  LOGGER_.error("exception caught:" + e.getMessage());}但我不確定這些是否是正確的方法。此外，如果 ulimit -n 甚至被修改了。
