[GRASS5] GRAS_PAGER

[Helena Mitasova]

I have recently tried GRASS6 on Mac and MSWindows and found that
GRASS_PAGER uses less instead of more, which is very incovenient
(and for some people confusing, because you have to type q after
running g.list to get your grass prompt back). Is there a reason 
why it cannot be set as Lorenzo suggests and why is there the 
less alternative? (see my guess below) People who haven't used 
GRASS before would not realize that this behavior can be changed
as Hamish suggests below.

thanks for any hints,

Helena

My answer:

Lorenzo,

it is there already and it looks like it uses less if it cannot find
more under /bin ???

 173 # Once the new environment system is committed we can delete these
lines
    174 # Export the PAGER environment variable for those who have it
set
    175 if [ "$PAGER" ] ; then
    176     export PAGER
    177 fi
    178
    179 # Set some environment variables if they are not set
    180 if [ ! "$GRASS_PAGER" ] ; then
    181     if [ -x /bin/more ] ; then
    182         GRASS_PAGER=more
    183     else
    184         GRASS_PAGER=less
    185     fi
    186     export GRASS_PAGER
