chuf is a command line utility that transforms stdin to stdout by sending predefined chunks through the specified FILTER. A chunk is defined by a BEGIN and END byte sequence within the stream. Anything not within a chunk is passed along unmodified.
chuf BEGIN END FILTER
BEGIN : Byte sequence designating beginning of chunk
END : Byte sequence designating end of chunk
FILTER : Command filter to transform chunk. A multiple parameter command filter must be enclosed in quotes.
$ echo "the quick {U}brown fox{R} jumped over the lazy dog" | \\
chuf {U} {R} "tr [:lower:] [:upper:]"
