| .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. | |
