java调用shell脚本,并获得结果集的例子

/**
 * 运行shell脚本
 * @param shell 需要运行的shell脚本
*/
public static void execShell(String shell) {
    try {
        Runtime rt = Runtime.getRuntime();
        rt.exec(shell);
    } catch (Exception e) {
        e.printStackTrace();
    }
}


/**
 * 运行shell
 *
 * @param shStr
 *            需要执行的shell
 * @return
 * @throws IOException
 */
public static List runShell(String shStr) throws Exception {
    List<String> strList = new ArrayList();

    Process process;
    process = Runtime.getRuntime().exec(new String[] {"/bin/sh","-c",shStr},null,null);
    InputStreamReader ir = new InputStreamReader(process
            .getInputStream());
    LineNumberReader input = new LineNumberReader(ir);
    String line;
    process.waitFor();
    while ((line = input.readLine()) != null) {
        strList.add(line);
    }

    return strList;
}

注:如果sh中含有awk,一定要按new String[]{"/bin/sh","-c",shStr}写,才可以获得流.
