[Q] correct syntax for flashable zip topic

hi guys, easy question for you hope you can help :)

I have a flashable zip that deletes some files from /system, and to do that in updater-script I have for example:

Code:

---

delete_recursive(
        "/system/app/BasicDreams"
);

---

....now, instead of deleting them I would like to move them somewhere else in /system, for example a backup directory ( /system/__Backup ), but don't know what would I need to add in updater-script file to actually:

1. create the "__Backup" folder in /system
2. move "BasicDreams" folder to that directory

I know the unix commands I should run for that ( `mkdir /system/__Backup` and then `mv -rf /system/app/BasicDreams /system/__Backup` ) but don't know what is the correct syntax for these commands to be correctly executed in updater-script :(

can someone please help me? :fingers-crossed:

thanks in advance bye!
