Ghostscript: pagination via command line

question (maybe stupid, maybe not)

Windows use a graphical interface for ghostscript

free PDF filling tools - www.freepdffill.com

one tool of this interface, allows you to print numbers on pages

a pdf, choosing size, position, font ... etc ...

Now I switched to linux, I have ghostscript, so I guess I am able to do the same from the command line, but I cannot find or understand how Command line parameters for pagination

Can anyone help me?
