I was reading the man pages and was going to list the devices available to ghostscript. I misread and did this:

gs devicenames ==

Of course that didn't do anything but an error. Then I realized I was supposed to run gs like a program and then type in devicenames == which gave me the names.

However, now gs is fubar. I can't do what I want without it giving the same error (which it didn't used to do that before).


gs -sDEVICE=pdfwrite -dCompatibilityLevel=1.4 -dPDFSETTINGS=/screen -dNOPAUSE -dQUIET -dBATCH -sOutputFile=MyPDFFile-New.pdf MyPDFFile.pdf

Now this is run in the same directory that MyPDFFile.pdf is in so it does exist and I was sure to type it exactly (matching upper and lower case). However, I get this:

Error: /undefinedfilename in (MyPDFFile.pdf)
Operand stack:

What is going on? It worked before...

Can someone tell me how to reset the configuration so it will work again?
