The command you provided is used to modify the PATH environment variable in a Unix-like operating system, such as Linux or macOS. The PATH variable is a list of directories that the operating system searches when you enter a command in the terminal.
export PATH="/usr/local/opt/[email protected]/bin:$PATH" adds the directory
/usr/local/opt/[email protected]/bin to the beginning of the PATH variable. This means that when you run a command in the terminal, the system will check this directory first for the corresponding executable file. If the file is found there, it will be executed. If not, the system will continue searching the remaining directories in the PATH variable.
In this specific case, it appears that the command is adding the directory for the PHP version 8.1 to the PATH. This allows you to use the PHP 8.1 command-line tools and executables conveniently from anywhere in the terminal.
