I have a binary file with data. Each block of 48 bytes is a record. I

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? Thanks!


perl or python.

In perl you want "unpack" and in python you probaly want "struct.unpack".
