查看CPU、内存使用率

GREEN='\033[0;32m'
YELLOW='\033[0;33m'
BLUE='\033[0;34m'
NC='\033[0m' # 无颜色

while true; do
    # 获取所有进程的CPU使用率和内存使用率
    cpu_usage=$(ps aux | awk '{sum_cpu += $3} END {print sum_cpu}')
    mem_usage=$(ps aux | awk '{sum_mem += $4} END {print sum_mem}')
    
    # 打印结果，带有时间戳、分隔线和颜色高亮
    echo -e "${BLUE}==============================${NC}"
    echo -e "${YELLOW}Timestamp: $(date)${NC}"

    # 等待5秒后再次执行
