Options are processed from left to right and must appear before any filename argument.
 
| 
 |  -echo on|off |  
Specify on to enable echoing commands to standard output as
they are read or off to disable.  The default is
off.
 
| 
 |  -escape unix|windows |                | 
 | Parse using unix or windows syntax |  
Commands must be parsed from the input stream and escaping needs to be
used to protect spaces or quoting characters in the input. Specify
unix to use unix-style command line parsing or windows
for Microsoft Windows command shell style parsing. The default depends
on if the software is compiled for Microsoft Windows or for a
Unix-type system (including Cygwin on Microsoft Windows).  It is
recommended to use unix syntax because it is more powerful and more
portable.
 
| 
 |  -fail text |                | 
 | text to print if a command fails |  
When feedback is enabled, this specifies the text to print when the
command fails.  The default text is FAIL.
 
| 
 |  -feedback on|off |  
Print text (see -pass and -fail options) feedback after each
command to indicate the result, the default is off.
 
| 
 |  -help |  
Prints batch command help.
 
| 
 |  -pass text |                | 
 | text to print if a command passes |  
When feedback is enabled, this specifies the text to print when the
command passes.  The default text is PASS.
 
| 
 |  -prompt text |                | 
 | Prompt text to use for command line |  
If no filename argument was specified, a simple command prompt appears
where you may enter GraphicsMagick commands.  The default prompt is
GM>.  Use this option to change the prompt to something else.
 
| 
 |  -stop-on-error on|off |                | 
 | Specify if command processing stops on error |  
Normally command processing continues if a command encounters an
error.  Specify -stop-on-error on to cause processing to quit
immediately on error.
