process substitution

Process substitution is a technique used in programming and command-line interfaces that allows the output of a process (a command or program) to be treated as a file. Instead of creating temporary files, the system dynamically provides access to a process's output or input as if it were a file, enabling seamless data exchange between commands. This method simplifies complex command chaining, improves efficiency, and avoids cluttering your workspace with temporary files. It’s particularly useful in scripting and automation, making data handling more flexible and streamlined.
