首先须要root手机。
然后，“Win + R”，打开cmd窗体。以下以copy d:\1.txt到/system/文件夹为例说明。
adb push
source(localpath) dest(mobilepath)
d:\>adb push 1.txt /system
failed to copy ‘1.txt‘ to ‘/system/1.txt‘: Read-only file system
须要先挂载/system分区
adb devices查看当前连接的设备
d:\>adb devices
List of devices attached
4d00a813e1e84041 device
假设这个列表里没有设备，须要检查手机连接。
adb shell远程登录手机的linux系统
d:\>adb shell
[email protected]:/ $
su命令取得超级用户权限。命令提示符会由”$”变成”#”
[email protected]:/ $ su
[email protected]:/ #
df命令查看文件系统的磁盘空间占用情况
[email protected]:/ # df

/mnt/shell/container 8.90G 7.66G 1.24G 4096
/system分区是2.69G
接着查看/proc下的partitions
[email protected]:/ # cat /proc/partitions
major minor #blocks name
253 0 409600 zram0
179 0 15388672 mmcblk0
179 1 4096 mmcblk0p1
179 2 4096 mmcblk0p2
179 3 20480 mmcblk0p3
179 4 4096 mmcblk0p4
179 5 4096 mmcblk0p5
179 6 4096 mmcblk0p6
179 7 20480 mmcblk0p7
259 0 8192 mmcblk0p8
259 1 8192 mmcblk0p9
259 2 8192 mmcblk0p10
259 3 8192 mmcblk0p11
259 4 8192 mmcblk0p12
259 5 90112 mmcblk0p13
259 6 262144 mmcblk0p14
259 7 4096 mmcblk0p15
259 8 573440 mmcblk0p16
259 9 12288 mmcblk0p17
259 10 4096 mmcblk0p18
259 11 2121728 mmcblk0p19
259 12 2830336 mmcblk0p20
259 13 9379840 mmcblk0p21
依据大小选择挂载mmcblk0p20
[email protected]:/ # mount -o rw,remount /dev/block/mmcblk0p20 /system
我试了不带分区，也是能够的
[email protected]:/ # mount -o rw,remount /system
使用完之后能够再改为read-only
[email protected]:/ # mount -o ro,remount /dev/block/mmcblk0p20 /system
运行拷贝
d:\>adb push 1.txt /system
failed to copy ‘1.txt‘ to ‘/system/1.txt‘: Permission denied
ls -l命令查看文件权限，能够看到shell用户没有读/写权限。改动文件权限
[email protected]:/ # chmod 777 /system
再push，成功。
从手机复制文件到电脑是类似的。adb pull source(mobilepath) dest(localpath)
d:\>adb pull /system/1.txt D:\game
假设提示"Permission denied"，就须要改动文件权限，chmod xxx 文件名称。假设想改动文件夹下全部文件属性，能够用chmod xxx *.*。
ps. csdn的排版真烂啊
