Linux-Raspberry Pi system partition There are two main partition commands: fdisk and parted.Both commands require the root permission,First, we will introduce the fdisk command: Fdisk allows you to view the usage of the current file system. fdisk -l Because I installed the system on the SD card, the partition starts with/dev/mmcblk0. We can see that there are currently three actual partitions (/dev/mmcblk

Because our campus network can be connected to the Internet only through web page authentication, it is really difficult for me to do this only for those who have no GUI on the command line. I want to write a script in Python to automatically fill in the form, and then post it. Later I found that Linux has a curl command, and Raspberry Pi has been installed by default (My ubuntu10.04 does not exist ). Now,
