I put together a terse summary of extended regular expressions at
<http://www.unidata.ucar.edu/software/ldm/ldm-current/basics/ERE.html>.
It also has a link to the definitive web pages.

Because the dollar-sign means end-of-string, it would have to be at the
end of the regular expression.

> Any help you can provide is greatly appreciated.

I think this will do what you want:

EXP (........_...._sport_goesimager_conus_icecap.gz)$
        FILE /home/ldm/data/ICECAP/\1

Be sure to separate the fields with tabs and not spaces.

You can verify the regular expression via the command 
"pqcat -vl- -o 3600 -f EXP -p ... >/dev/null"
