FWIW I think this output is only suitable for people with robot brains.
It's only fractionally better than using a hex viewer.

Among other things it shows the header password as numerical values (120
120 120 is xxx), which is not very useful.

Also obviously it only dumps the packet header using the first 58 bytes,
not the message headers within.

I suppose it's better than nothing, but I'm not sure why you'd suggest
using a one-liner when there were far better solutions already offered!

$ head -c 58 < test.pkt | perl -e 'while(<>){{at}pktHeader =
unpack("S12C10S4C2S7", $_);};\
  print join("\n",{at}pktHeader),"\n";'

pktlist or pktdump are a lot friendlier:
