What does the following command do?

mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system

When I typed mount –help on shell I could find out -o is for options. But can not understand why the , between remount,rw.

If any one can explain the complete command please. I read the above command while I was trying to remove some BloatWare from my LG Optimus One p500 , after rooting it.

    Try this on for size:

    • mount: the actual command
    • -o remount,rw: the option passed to mount (remount means dismount, and remount; rw means mount as read/write) The -o flag can take several comma separated parameters.
    • -t yaffs2: use the yaffs2 filesystem type
    • /dev/block/mtdblock3: mount the block device found at /dev/block/mtdblock3
    • /system: mount the specified block device at /system
