- l – Command-line arguments are passed individually (a list) to the function.
- v – Command-line arguments are passed to the function as an array (vector) of pointers.
- e – An array of pointers to environment variables is explicitly passed to the new process image.
- p – Uses the PATH environment variable to find the file named in the path argument to be executed.
