Answers:
相信您要:cat /proc/mtd
。
也有用:mount
。
cat /proc/partitions
同时显示所有分区的列表。我认为mount
与相关cat /proc/mounts
。啊,好'ol/proc
dev: size erasesize name
是否以su身份运行。 android.stackexchange.com/q/53225/693
/proc/mtd
并非在所有设备上都可用,而/proc/partitions
应该在所有设备上都可用。
我通常结合使用以下4个命令并将它们关联起来,因为这些命令中的每一个都提供了可能需要的信息。
总结:
使用df
列出了文件系统路径别名和大小信息,如下所示(总大小,已使用,可用和块大小)
输出示例:
root@ks01lte:/sdcard # df
df

使用cat /proc/mounts
显示分区文件路径,别名,文件系统类型,startnig索引节点,块数,读/写状态(以及我不确定的单个分区的其他参数)
cat /proc/mounts
可能有点混乱,但是如果您逐行(逐项输入)仔细阅读,则会得到相关信息 输出示例:
root@ks01lte:/sdcard # cat /proc/mounts
cat /proc/mounts
rootfs / rootfs ro,relatime 0 0
tmpfs /dev tmpfs rw,seclabel,nosuid,relatime,size=931840k,nr_inodes=124673,mode=755 0 0

使用cat /proc/partitions
您将获得实际的分区名称标识符和分区中的块数。
输出示例:
root@ks01lte:/sdcard # cat /proc/partitions
cat /proc/partitions
major minor #blocks name
253 0 1048576 vnswap0
179 0 15388672 mmcblk0
179 1 15360 mmcblk0p1
179 2 58816 mmcblk0p2
179 3 512 mmcblk0p3
179 4 32 mmcblk0p4
179 5 32 mmcblk0p5

使用ls -al /dev/block/platform/msm_sdcc.1/by-name
您可以获取分区别名和实际分区文件的路径之间的映射(还可以获取所有者,其用户组等)。
输出示例:

ls -al /dev/block/platform/msm_sdcc.1/by-name

/dev/block/platform/xxx/by-name
。/proc/emmc
确实有,这很相似,但是没有列出启动分区。也没有cat /proc/mounts
,而是使用mount
。
可以从中获得更多有用的信息parted
。块设备为/dev/block/mmcblk0
以下示例:
~ # parted /dev/block/mmcblk0 print

旧线程,但发现没有其他人提到过……只是以防万一有人发现它有用。
ls -la /dev/block/bootdevice/by-name
该目录包含所有分区的命名符号链接。
