After reading a bit about extended regular expressions and having a few actually work correctly in sed scripts, I tried one in egrep and it isn't working although there are no errors. I was hoping to get only the A records from a dns zone file so the expression I used is: egrep [[:space:]IN[:space:]A[:space:]] zone_file >h0 Had it worked, all that would have appeared in the h0 file was all the A or Address records. Instead, I get those plus almost everything else in the file. It is obviously not filtering correctly. Plain grep produces a 0-length output file so that is not too useful either. Putting double quotes around the RE didn't help either. It seems to match almost everything. Thanks for any good ideas.
