NAME¶

SYNOPSIS¶

DESCRIPTION¶

By default, byte 0 is at the center of the circle and next bytes until 256 are situated counterclockwise around the center.

bytes-circle expects a colour terminal, though other options are available.

The ASCII art produced uses this char array to represent increment values of 1/4*sigma from the statistic's mean: . , - ~ + * o O # @

This ranges from zero (.) on the left, to 9/4*sigma (@) on the right. If value is zero or over the mean the char is printed green. If it is below the mean, it's printed red. A (blue) '=' char represents a byte value that doesn't appear in the file.

OPTIONS¶

files

One or more files. If no file is indicated, standard input is used.

-o {0|1|2|3}

1=no color | 2=numbers | 3=uncoloured numbers

-B

Stop processing files on first error encountered.

-b

No color. In this case, ASCII art is adjusted so the zero sigma is at the middle of the chars array (char '*'). Increments are 1/2*sigma.

-l

List number of bytes counted, from 0 to 255.

-L

List number of bytes counted, excluding zero valued.

-Z

List number of bytes counted, but only zero valued.

-n

Use numbers. In this case, coloured numbers are used to represent values from 0 to 9/4*sigma.

-r

Restrict statistics to the byte values that appear in the file, not to the 256 default. This only makes a difference if there are byte values that do not appear in the file.

-u

Use uncoloured numbers. In this case, numbers are used to represent positive deviations from 0 to 9/4*sigma, and letters are used to represent negative deviations from 'a' (-0) to 'i' (-9/4)*sigma.

-v

Show program version and list chars used in coloured circle.

-h

Show summary of options.

-z {0-255}

Show a second circle centered on indicated byte bucket. A zero value is equivalent to 127 for ease of use. This way a second view of the statistics is available for data disaggregation.
