Keep getting error messages in ghostscript when using the documented ghostscript syntax

问题

I am new to ghostscript and I cannot figure out the syntax. Whenever I try the simplest of commands ex -h or -? I get an error and I have tried them in all sorts of combinations.

回答1:

You're inside the PostScript interpreter and what you're entering isn't PostScript.

You need to run the exe on the command line with -h (there are a couple of binaries in the distribution, one will respond correctly).

回答2:

What I tried is as follows:

The directory of Ghostscript installation on my system (the path to the file "gswin32c.exe"):

C:\Program Files (x86)\gs\gs9.10\bin

Then I opened windows command prompt (our normal command prompt window) and did this:

C:\>cd C:\Program Files (x86)\gs\gs9.10\bin

then..

C:\Program Files (x86)\gs\gs9.10\bin>gswin32c.exe -h

there you go....

the help instructions got displayed, means everything was well and good !
