페도라 설치 후 man strcpy 했더니 없다네..

무슨 패키지가 설치되지 않았을까?

위 패키지 man-pages 와 man-pages-ko 를 yum 을 이용하여 설치하면 끝~

아래 예제 코드를 SystemDateTimeSyncTest.java 파일로 작성한다.

실행시 반드시 루트 권한으로 실행하여야 

public class SystemDateTimeSyncTest {
  public static void main(String[] args) {
    this.updateSystemDateTime("20100217161550"); // 2010-02-17 16:15:50
  }

  private boolean updateSystemDateTime(String recvMsg)
  {
    String strDate = null;
    String[] cmds = null;
    BufferedReader br = null;
    Process proc = null;
    boolean result = false;
    try {
      strDate = recvMsg.substring(0, 4) + "-" + recvMsg.substring(4, 6) + "-" + recvMsg.substring(6, 8) + " "
        + recvMsg.substring(8, 10) + ":" + recvMsg.substring(10, 12) + ":" + recvMsg.substring(12, 14);
      cmds = new String[] { "/bin/date", "-s", strDate };

      System.out.println("user.name: " + System.getProperty("user.name"));
      Runtime runtime = Runtime.getRuntime();
      runtime.traceInstructions(true);
      runtime.traceMethodCalls(true);
      proc = runtime.exec(cmds);
      br = new BufferedReader(new InputStreamReader(proc.getInputStream()));

      String execLine = null;
      while( (execLine = br.readLine()) != null) {
        System.out.println("----------> " + execLine);
      }

      br.close();
      br = null;

      br = new BufferedReader(new InputStreamReader(proc.getErrorStream()));

      while( (execLine = br.readLine()) != null) {
        System.out.println("----------> " + execLine);
      }
      proc.waitFor();
      System.out.println("Exit value: " + proc.exitValue());
      result = true;
    } catch(Exception e) {
      e.printStackTrace();
