This article will explain in detail about establishing symbolic connections in PHP. The editor thinks it is very practical, so I share it with you as a reference. I hope you can gain something after reading this article. Introduction to establishing symbolic links in PHP A symbolic link is a special file type that points to another file or directory. When a symbolic link is accessed, the system automatically redirects to the target file or directory as if accessing the original file or directory directly. In PHP, you can use the symlink() function to create symbolic links. Syntax symlink(string$target,string$link) where: $target: The path to the target file or directory to be linked. $link: The path of the symbolic link. ginseng

When using Python to open the terminal under Linux, an error is reported. Scenario 1: Execute automated tasks on Jenkins. Use the Jenkins user (with sudo permissions) when executing the test task. The test script is executed in Linux (background). When the following code is executed, an error is reported: os.system (f"/usr/bin/konsole-e{cmd_orin2_10s}") Scenario 2: There is no problem when the test script is executed locally. When executing locally, using the root user, the command window can be opened normally. Error log: 17:44:03qt.qpa. xcb:couldnotconnecttodisplay

iTerm2 has more functions, is more customized and has better ease of use than macOS's default terminal. 1. In terms of functions, iTerm2 supports split screen, enhanced search, hotkey windows and mouse interaction, while the terminal only provides basic functions; 2. In terms of appearance, iTerm2 supports preset themes, hyphen fonts and background pictures, while the terminal only provides basic style settings; 3. In terms of integration, iTerm2 supports Python/AppleScript scripts, better Tmux integration and task completion notifications, and the terminal has weak integration capabilities; 4. In terms of performance, iTerm2 renders faster and has better high resolution display, but the terminal is more stable due to the native system support. Therefore, if you use optional terminals for daily use, heavy developers are more suitable for iTerm2

There are three common methods to switch users in the terminal: 1. Use the suusername command and enter the target user password to switch, which is suitable for knowing the target user password; 2. Use sudosu and enter the current user password to switch to root, and the current user must have sudo permissions; 3. Use sudo-i-uusername to simulate the target user login environment, without the target user password, but the corresponding permissions are required. In addition, sudo-uusernamecommand can be used to temporarily execute the specified command, and it is not recommended to use root permissions for a long time to avoid the risk of incorrect operation.

pwd displays the current location, ls view the file, cd switches the directory; 2. touch creates empty files, mkdir creates folders, rm deletes files or -r deletes folders, mv renames or moves, cp copy files; 3. cat view content, open with default application, nano edits text; add Tab completion, ↑ checks history, Ctrl C termination, man checks help, and gradually practice to use Terminal proficiently.

Symbol links (symlinks) are special files pointing to another file or directory. The creation method is to use the ln-s command, with the syntax of ln-s[target path][link path], such as ln-s/Users/yourname/Development/myproject~/Desktop/myproject; precautions include ensuring the correct path, avoiding duplicate names, checking permissions, and paying attention to the current directory location when using relative paths, otherwise the link may be invalid.

It is actually not difficult to use Terminal for Mac. Mastering the basic operations can be used daily. 1. Opening methods include Spotlight search, searching in utility tools or adding to Dock; 2. Commonly used commands include ls column directory, cd switching path, pwd display path, mkdir new folder, open. Open Finder; 3. Installing programs such as Homebrew needs to run official website commands, and then use brewinstall to install the tool and remember to update; 4. Custom settings can be customized, such as OhMyZsh beautifying the interface, setting aliases commands, and Tab complete paths to improve efficiency.
