[mapserver-users] mapserv cli and run-time substitution

[andy]

Hi,
I have this map file [1] in which I use this simple class expression
"EXPRESSION ([year] < 1976)".
Starting from it, I'm able to create the png output I want, running:

mapserv -nh "QUERY_STRING=map=data.map&mode=map" >out.png

But if I replace the hard coded year value with '%year%', and then I run
this command

mapserv -nh "QUERY_STRING=map=data.map&mode=map&year=1976" >out.png

I have a wrong PNG output, in which the layer that has the run-time
substitution variable is not rendered properly, because it seems that the
value is not collected.

What's wrong with my steps? How to use run-time substitution via cli?

Thank you,

Andrea
