Well.. R77.30 is a long expired Check Point version that doesn't have all the new tools recent versions do.
My Top 10 list of possible solutions:
1 > Upgrade your R77.30 management in a Lab-VM to R81 and extract the data you look for with the tools mentioned here.
2 > Grab cpdb2web for R77.30 as described in sk64501 and run cpdb2html/cpdb2web to collect your data of interest.
3 > Grab Confwiz v1.25 and export the data from your R77.30 management easily.
4 > Use the included bash grep functionality to grep your data of interest directly from your Objects_5_0.C
5 > Use CPParser to extract your data of interest.
6 > Use odumper to grep your data of interest.
7 > Use
echo -e "print \n-q\n" | dbedit -local to grep your data of interest (skI3301).
8 > Use other's dbedit examples.
9 > Use cpmiquerybin to grep your data of interest
10 > Search GitHub for applicable scripts to parse your data of interest. (Examples: 1, 2, 3)
