very simple off-topic question regarding command line viewing of postscr

  I'm trying to simplify my workflow. I think I want to generate
postscript files instead of pdf files when using Lilypond.  I already
know how to do that.  But what I need to know is, on a Mac, how to
display the postscript file from the command line.  I used to do this
all the time a long time ago when I used UNIX and Linux, but homebrew
gs doesn't display the postscript.  I do not want to use preview.

  This used to be a TRIVIAL thing to do when I was younger, but now I
am old and my brain just isn't what it used to be.

  I've looked at several man pages and/or info and/or help (lastly

Current attempt:

/opt/homebrew/Cellar/ghostscript/9.56.1_1/bin/gs -sDEVICE=display

zsh: segmentation fault
/opt/homebrew/Cellar/ghostscript/9.56.1_1/bin/gs -sDEVICE=display

So, what flags should I be using just to display the postscript?
