Quick scan of IDXFORMAT "8" files

I am running on Redhat and years ago when I had my data files with the index info split out I could do a "grep" of the data portion. Now when I try to quickly scan for something I get "Binary file X.LDF matches"

Any suggestions?  I know I can use ODBC connectors and I do, but just looking for a quick utility like I used to have.

Thanks for any suggestions.
