.TH FREQ 1 .SH NAME freq \- print histogram of character frequencies .SH SYNOPSIS .B freq [ .B -cdorx ] [ .I file ... ] .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. .SH SOURCE .B /sys/src/cmd/freq.c .SH SEE ALSO .IR utf (6), .IR wc (1)
