一. 基础语法篇
1.copy_dir
语法:copy_dir <src-dir> <dst-dir> [<timestamp>]
<src-dir>表示原文件夹,<dst-dir>表示目的文件夹,[<timestamp>]表示时间戳
作用:将<src-dir>文件夹中的内容复制到<dst-dir>文件夹中。<dst-dir>文件夹中的原始内容将会保存不变,除非<src-dir>文件夹中有相同的内容,这样<dst-dir>中的内容将被覆盖
举例:copy_dir PACKAGE:system SYSTEM:(将升级包中的system文件夹复制到手机中)

2.format
语法:format <root>
<root>表示要格式化的分区
作用:格式化一个分区
举例:format SYSTEM:(将手机/system分区完全格式化)
注意:格式化之后的数据是不可以恢复的

3.delete
语法:delete <file1> [... <fileN>]
<file1> [... <fileN>]表示要格式化的文件,可以是多个文件用空格隔开
作用:删除文件1,2到n
举例:delete SYSTEM:app/Calculator.apk(删除手机systen文件夹中app中的Calculator.apk文件)

4.delete_recursive
语法:delete_recursive <file-or-dir1> [... <file-or-dirN>]
<file-or-dir1> [... <file-or-dirN>]表示要删除的文件或文件夹,可以使多个,中间用空格隔开
作用:删除文件或者目录,删除目录时会将目录中的所有内容全部删除
举例:delete_recursive DATA:dalvik-cache(删除/data/dalvik-cache文件夹下的所有内容)

5.run_program
语法:run_program <program-file> [<args> ...]
<program-file>表示要运行的程序,[<args> ...]表示运行程序所加的参数
作用:运行终端程序
举例:run_program PACKAGE:install_busybox.sh(执行升级包中的install_busybox.sh脚本)

6.set_perm
语法:set_perm <uid> <gid> <mode> <path> [... <pathN>]
<uid>表示用户名称,<gid>表示用户组名称,<mode>,表示权限模式,<path> [... <pathN>]表示文件路径,可以使多个,用空格隔开
作用:设置单个文件或目录的所有者和权限,像linux中的chmod、chown或chgrp命令一样,只是集中在了一个命令当中
举例:set_perm 0 2000 0550 SYSTEM:etc/init.goldfish.sh(设置手机system中的etc/init.goldfish.sh的用户为root,用户组为shell,所有者以及所属用户组成员可以进行读取和执行操作,其他用户无操作权限)

7.set_perm_recursive
语法:set_perm_recursive <uid> <gid> <dir-mode> <file-mode> <path> [... <pathN>]
<uid>表示用户,<gid>表示用户组,<dir-mode>表示文件夹的权限,<file-mode>表示文件的权限,<path> [... <pathN>]表示文件夹的路径,可以多个,用空格分开
作用:设置文件夹及文件夹中的文件的所有者和用户组
举例:set_perm_recursive 0 0 0755 0644 SYSTEM:app(设置手机system/app文件夹及其中文件的用户为root,用户组为root,app文件夹权限为所有者可以进行读、写、执行操作,其他用户可以进行读取和执行操作,其中的文件的权限为所有者可以进行读写操作,其他用户可以进行读取操作)

8.show_progress
语法:show_progress <fraction> <duration>
<表示一个小部分> <表示一个小部分的持续时间>
作用:为下面进行的程序操作显示进度条,进度条会根据<duration>进行前进,当操作时间是确定的时候会更快
举例:show_progress 0.1 0(显示进度条当操作完成后前进10%)

9.symlink
语法:symlink <link-target> <link-path>
<link-target>表示链接到的目标,<link-path>表示快捷方式的路径
作用:相当于linux中的ln命令,将<link-target>在<link-path>处创建一个软链接,<link-target>的格式应为绝对路径(或许相对路径也可以),<link-path>为“根目录:路径”的形式
举例:symlink /system/bin/su SYSTEM:xbin/su(在手机中system中的xbin中建立一个/system/bin/su的快捷方式)
10.assert
语法:assert <boolexpr>

作用:此命令用来判断表达式boolexpr的正确与否,当表达式错误时程序终止执行※此作用有待验证

11.package_extract_file/dir语法:package_extract_file(file/dir,file/dir)
作用:提取包中文件/路径
举例:package_extract_dir("system", "/system");
package_extract_file("system/bin/modelid_cfg.sh", "/tmp/modelid_cfg.sh");


12.write_radio_image

语法:write_radio_image <src-image>
作用:将基带部分的镜像写入手机,<src-image>表示镜像文件
举例:write_radio_image PACKAGE:radio.img

13.write_hboot_image

语法:write_hboot_image <src-image>
作用:将系统bootloader镜像写入手机,<src-image>表示镜像位置,此命令在直到在所有的程序安装结束之后才会起作用

举例:write_hboot_image PACKAGE:hboot.img
14.write_raw_image语法:write_raw_image <src-image> <dest-root>
作用:将boot.img写入手机,里面包含了内核和ram盘
举例:write_raw_image PACKAGE:boot.img BOOT:

二、根目录以及分区的定义(在Android源代码的root.c文件中定义)

根目录: Linux 块设备 /挂载点/ 文件系统 大小 描述
BOOT: /dev/mtdblock[?] / (RAM) Raw 内核、内存盘和引导配置。
DATA: /dev/mtdblock5 /data/ yaffs2 91904kb 用户、系统配置,软件配置以及软件(没有a2sd的话)
CACHE: /dev/mtdblock4 /cache/ yaffs2 30720kb OTA缓存,recovery/更新配置及临时文件夹
MISC: /dev/mtdblock[?] N/A Raw,[?]kb (等待添加)
PACKAGE: (相对于刷机包) N/A 刷机包的伪文件系统。
RECOVERY: /dev/mtdblock[?] / (RAM) Raw,[?]kb recovery和更新环境的内核和内存盘。类似于BOOT:。
SDCARD: /dev/mmcblk0(p1) /sdcard/ fat32 32MB-32GB TF卡。通常刷机包就放在这里。
SYSTEM: /dev/mtdblock3 /system/ yaffs2 92160kb 系统分区,静态且是只读的。
TMP: /tmp/ (RAM) 标准的Linux临时文件夹 在关机/重启时清空。

三. 实例分析进阶篇

呵呵,大家来看看这段代码是不是有种熟悉的感觉啊,这就是在SwiftDroid_v1.8_recovery_BY_mur4ik刷机包中的updater-script文件!
