Di seguito riporto la sintassi dei comandi da inserire nel file updater-script di un file update.zip utilizzato per flashare gli aggiornamenti su una rom Andorid. Il tutto è stato ripreso da XDA, da qui e qui.
Mounting Partition
MTD
mount("MTD", "system", "/system");
mount("MTD", "userdata", "/data");
mount("MTD", "cache", "/cache");
mount("MTD", "sdcard", "/sdcard");EMMC
mount("ext4", "EMMC", "/dev/block/mountpoint", "/system");
mount("ext4", "EMMC", "/dev/block/mountpoint", "/data");
mount("ext4", "EMMC", "/dev/block/mountpoint", "/cache");
mount("ext3", "EMMC", "/dev/block/mountpoint", "/system");
mount("ext3", "EMMC", "/dev/block/mountpoint", "/data");
mount("ext3", "EMMC", "/dev/block/mountpoint", "/cache");
mount("ext4", "EMMC", "/dev/block/mmcblk0p23", "/system");
mount("ext4", "EMMC", "/dev/block/mmcblk0p24", "/data");
mount("ext4", "EMMC", "/dev/block/mmcblk0p25", "/cache");Unmounting Partitions
unmount("/system");
unmount("/data"); OR unmount("/userdata");
unmount("/cache");
unmount("/sdcard");Format Partitions
format("MTD", "system");
format("MTD", "cache");
format("MTD", "data");
format("MTD", "boot");
format("ext4", "EMMC", "/dev/block/mountpoint");
format("ext3", "EMMC", "/dev/block/mountpoint");
format("ext4", "EMMC", "/dev/block/mmcblk0p23");
format("ext4", "EMMC", "/dev/block/mmcblk0p24");
format("ext4", "EMMC", "/dev/block/mmcblk0p25");
format("ext4", "EMMC", "/dev/block/mmcblk0p22", "/boot");Copy files from .zip file to phone partition or sd card:
package_extract_dir("Source", "Destination");Example:
package_extract_dir("system", "/system");
package_extract_dir("data", "/data");
package_extract_dir("sdcard", "/sdcard");Output a line of text:
ui_print("Text Here");Delete a file:
delete_recursive("file/path");
delete("/path/to/file");Run Program
run_program("command", "parameter_1", "parameter_2" [, "parameter_2"[, ... ] ] );Example:
run_program("/sbin/busybox", "umount", "/sd-ext");Symbolic Link
symlink("source", "destination")Example:
symlink("/data/etc/hosts", "/system/etc/hosts")
