.SH DESCRIPTION
.I Freq
reads the given files (default standard input)
and prints histograms of the character frequencies.
By default,
.I freq
counts the value of each byte;
under the
.B -r
option it instead counts
.SM UTF
byte sequences, that is, runes.
.PP
Each non-zero entry of the table is printed preceded by the byte value,
in decimal, octal, hex, and
Unicode
character (if printable).
If any options are given, the
.BR -d ,
.BR -x ,
.BR -o ,
.B -c
flags specify a subset of value formats: decimal, hex, octal, and
character, respectively.
