What is Process Substitution?
Process substitution allows you to treat the output of a process as if it were a file. It provides a way to pass the output of one command as input to another command, without using temporary files or named pipes. This is achieved by creating a temporary file-like object (either a named pipe or a file in /dev/fd) that the command writes its output to, and then passing the name of this object to another command as an argument.
