Bytes

bytes — Various commands for working with byte data.
bytes add — Add specified bytes to the binary input.
bytes at — Get bytes from the input defined by a range.
bytes build — Create a binary value from the provided arguments.
bytes collect — Concatenate multiple binary into a single binary, with an optional separator between each.
bytes ends-with — Check if binary data ends with a pattern.
bytes index-of — Returns start index of first occurrence of pattern in bytes, or -1 if no match.
bytes length — Output the length of any bytes in the pipeline.
bytes remove — Remove specified bytes from the input.
bytes replace — Find and replace bytes in binary data.
bytes reverse — Reverse the bytes in the pipeline.
bytes split — Split input into multiple items using a separator.
bytes starts-with — Check if binary data starts with a pattern.

Tips

bytes length counts binary bytes.

0x[01 02] | bytes length

encode utf8 turns text into bytes.

"ab" | encode utf8

Count the bytes in a short string.

"hi" | encode utf8 | bytes length

bytes reverse flips the byte order.

0x[01 02 03] | bytes reverse | bytes length

A byte count can become text.

"hi" | encode utf8 | bytes length | into string

Encode each string inside a closure.

["a" "b"] | each {|s| $s | encode utf8} | length

Four steps from text to a character count.

"hi" | encode utf8 | bytes length | into string | str length
