获取内存大小和硬盘大小：－－－－－－－－－－－－－－－－－－－Qt版本：

QString getMemTotal(){    QString memtotal;       QFile m_file;       m_file.setFileName("/proc/meminfo");       if(m_file.open(QIODevice::ReadOnly | QIODevice::Text)==true)       {              QTextStream stream(&m_file);              QString string=stream.readLine();              QStringList strlist = string.split(QRegExp("\\s+"), QString::SkipEmptyParts); // 匹配一个或多个"空格"，拆分为单个的单词             int total=strlist.at(1).toInt()/1024;             memtotal=strlist.at(0)+QString::number(total)+" MB";       }       m_file.close();       return memtotal;}QString getDiskTotal(){    QString diskTotal;    system("df -hl > /tmp/note.txt");    QFile m_file;    m_file.setFileName("/tmp/note.txt");    if(m_file.open(QIODevice::ReadOnly | QIODevice::Text)==true)    {           QTextStream stream(&m_file);           QString string=stream.readLine();           string=stream.readLine();           QStringList pieces = string.split(QRegExp("\\s+"), QString::SkipEmptyParts);// 匹配一个或多个"空格"，拆分为单个的单词            diskTotal=pieces.at(0)+":"+pieces.at(1);    }    m_file.close();    return diskTotal;}
