function list_dir($root){ $dirs = scandir($root); foreach($dirs as $dir){ if(is_dir($root.DIRECTORY_SEPARATOR.$dir) && (in_array($dir,array('.','..')) != '.')){ echo $root.DIRECTORY_SEPARATOR.$dir.PHP_EOL; list_dir($root.DIRECTORY_SEPARATOR.$dir); } }}list_dir('.');值得注意的几点：
1.递归一定要有跳出的条件，否则就是无限循环
2.使用常量DIRECTORY_SEPARATOR替代 "/"可以兼容linux和windows的不同目录分隔符
3.使用is_array($dir,array('.','..')) != '.'，而不是substr($dir,0,1) != '.' 是因为linux里面很多隐藏目录都是以"."开头的

Active Directory Users and Computers Missing [Fixed in 3 Ways]
Apr 20, 2023 pm 01:25 PM
Active Directory Users and Computers (ADUC) loss is one of the most frustrating issues reported by many Windows Pro users. ADUC is an incredible MMC snap-in that enables administrators to manage Microsoft Active Directory. However, for some reason it is missing in the Windows Server or Enterprise/Pro editions. Let’s take a closer look at why it’s missing and how we can fix it. Does Windows 11 have Active Directory? Active Directory is useful for anyone wanting to manage remote
Log in to Ubuntu as superuser
Mar 20, 2024 am 10:55 AM
In Ubuntu systems, the root user is usually disabled. To activate the root user, you can use the passwd command to set a password and then use the su- command to log in as root. The root user is a user with unrestricted system administrative rights. He has permissions to access and modify files, user management, software installation and removal, and system configuration changes. There are obvious differences between the root user and ordinary users. The root user has the highest authority and broader control rights in the system. The root user can execute important system commands and edit system files, which ordinary users cannot do. In this guide, I'll explore the Ubuntu root user, how to log in as root, and how it differs from a normal user. Notice
What is the difference between the root and alias directives in Nginx configuration?
May 12, 2023 pm 12:16 PM
Both root and alias can be defined in the location module, and are used to specify the real path of the requested resource, for example: location/i/{root/data/w3;} requests http://foofish.net/i/top.gif When this address is used, the corresponding real resource in the server is the /data/w3/i/top.gif file. Note: The real path is the value specified by root plus the value specified by location. And alias is just like its name. The path specified by alias is the alias of location. No matter how the value of location is written, the real path of the resource is the path specified by alias, such as
Step by step using Python to delete long path files under Windows

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. Now we need to delete the historical files of some of these subsystems to free up server space. Dozens of terabytes of data are stored together. Manual deletion will definitely not show up. We can only use program automation.
How to change the root user name in Linux
May 18, 2023 pm 07:50 PM
1. Taking CentOS as an example, after logging in, modify /etc/passwd and /etc/shadow, change the root starting on the first line to a new user name (such as admin), and save through wq! after modification. 2. After modifying and saving, it will take effect after restarting the server. You can check the permissions of the file and see that the account column has changed to admin, as follows: Note: The default user with the highest administrative authority in Linux is root, uid is 0. Only uid is recognized in the system, so as long as uid is 0, the system is regarded as the highest administrative user. However, there may be certain problems with applications. Some software uses the root user by default, so if you have limited understanding of software applications,

What does it mean that the current phone is not rooted?
Sep 19, 2023 pm 02:01 PM
The current mobile phone is not rooted, which means that the operating system of the mobile phone has not obtained super user permissions. In the Android system, root permission is the highest permission, which allows users to make in-depth modifications to the system and access sensitive system files. The phone is still in the default state. status, no system permissions have been modified, which means that users cannot directly access and modify system files, and cannot perform some advanced system operations. Ordinary users using unrooted mobile phones can use the basic functions of the mobile phone and install applications normally. There will be restrictions in certain special scenarios.
