| .SH DESCRIPTION |
| .I Freq |
| reads the given files (default standard input) |
| and prints histograms of the character frequencies. |
| By default, |
| .I freq |
| counts each byte as a character; |
| under the |
| .B -r |
| option it instead counts |
| .SM UTF |
| 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. |
