On: Finding CSV files that start with a BOM using ripg...

[xorcist]

The cmp in coreutils understands:

  -n, --bytes=LIMIT   compare at most LIMIT bytes

so head is not really necessary:

  find . -name '*.csv' -type f -exec cmp -sn 3 {} bom.dat \; -print

Using -exec as a filter is a nice feature more people should use. That -type was put there just to avoid directories.
