What are root permissions
1: What is root authority?
Root authority is a type of system authority, also called root authority. It can be understood as the same concept as SYSTEM permissions, but is higher than Administrator permissions. Root is the super administrator user account in Linux and Unix systems. This account has supreme power over the entire system, and he can operate all objects.
2: The principle of root
Currently, the common method to obtain Android root permissions is to use various system vulnerabilities to replace or add SU programs to the device to obtain Root permissions. After obtaining root permissions, a program will be installed to remind the user whether to give the program the highest permissions, which can prevent malware to a certain extent. SuperSU is usually used. This method is often called "incomplete root". "Complete ROOT" refers to replacing the device's original ROM to cancel the secure settings.

2. Viruses may invade during the process of obtaining root permissions.
3. Improper use may cause system damage.
4. Elevating privileges is risky.
5. Successful privilege escalation will cause system instability.

7. Strictly control the authorization requests of the program when installing software to prevent permissions from being exploited by malicious software.
8. Make sure that the phone has enough power. Theoretically speaking, the power of the phone should be above 50%. However, the editor here recommends that it be done at full capacity. If there is an error during the root process, We can make timely corrections when the battery is sufficient.

0x01 Background of the article Recently, the storage of a business system of the author's company is approaching the limit, and the server will soon be unable to run. Because the business system A contains multiple subsystems A1, A2, A3... An, the middle of these subsystems Due to design reasons, the stored files are all stored in the same parent directory. The only difference is that the names of files and folders generated by different subsystems all start with the name of the subsystem. For example, the files generated by the A1 subsystem are all named A1xxxxxx, and the file names generated by the A2 subsystem are all A2xxxxx.
