I have a binary file with data. Each block of 48 bytes is a record. I want to extract the first 8 bytes within each record. I'm thinking this should be possible with dd, but gawk, perl - anything goes. It just has to be fast, because the data files are ~ 1Gb. I can do this in C++ but I was just wondering if it can be done with existing well tested tools. Any suggestions?
