    ls ('cat >/proc/cpuinfo')
    ls ('cat >/proc/meminfo')

    谢谢。附上写好的代码。

    ```python
    #!/usr/bin/env python
    import time
    import psutil

    line_num = 1

    def print_line (str ):
    print str

    #function of Get CPU State
    def getCPUstate (interval=1 ):
    return (" CPU: " + str (psutil.cpu_percent (interval )) + "%")

    #function of Get Memory
    def getMemorystate ():
    phymem = psutil.phymem_usage ()
    buffers = getattr (psutil, 'phymem_buffers', lambda: 0 )()
    cached = getattr (psutil, 'cached_phymem', lambda: 0 )()
    used = phymem.total - (phymem.free + buffers + cached )
    line = " Memory: %6s" % (
    str (int (used / 1024 / 1024 )) + "M",
    )
    return line

    def poll (interval ):
    """Retrieve raw stats within an interval window."""
    # sleep some time
    time.sleep (interval )
    # get cpu state
    cpu_state = getCPUstate (interval )
    # get memory
    memory_state = getMemorystate ()
    return (cpu_state,memory_state )

    def refresh_window (cpu_state,memory_state ):
    #print current time #cpu state #memory
    print_line (time.asctime ())
    print_line (cpu_state )
    print_line (memory_state )

    try:
    interval =0
    while 1:
    args = poll (interval )
    refresh_window (*args )
    interval = 1
    except (KeyboardInterrupt, SystemExit ):
    pass
    ```
