本文介绍如何使用Linux系统下的终端命令进行SD卡的镜像文件备份及将镜像文件写回另一张SD卡的过程。涉及的步骤包括识别SD卡设备名、备份SD卡为镜像文件、卸载设备并使用dd命令将镜像文件写入目标SD卡。

                    
                    precondition:

* SD card(with image on it; hereafter short for SD1)

* SD card(without image on it; hereafter sort for SD2)

* PC (OS: Linux -> Ubantu)

* SD card reader

* IMG_FILE(target image file)
backup image of SD card(diagram: sd1 <> SD card reader <> PC)

* [input command on terminal of PC] df -h

* [find mounted sd card name] <device_name>

* [input command on terminal of PC to save as image file]

sudo dd if=/dev/<device_name> of=/<save_image_file_name>
write to SD card (diagram: sd2 <> SD card reader <> PC)

* [find mounted name of sd card] df -h; sudo fdisk -l

* [unmount them] sudo umount <device_name>

* [write to SD card] **sudo dd if=**IMG_FILE of=/dev/<device_name>
