Functions

func Head

func Head(opts ...any) gloo.Command[[]byte, []byte]

Head returns a Command that outputs the leading prefix of its input.

Flags:

• HeadLines (-n): emit the first N lines (default: 10).
• HeadBytes (-c): emit the first N bytes; collects the input, joins lines with newlines, truncates to N bytes, and emits the result as a line-oriented stream (one value per line, the newlines stripped).

HeadBytes takes precedence over HeadLines when set to a positive count.

Types

type HeadBytes

type HeadBytes int

HeadBytes sets the number of bytes to output (-c flag). When set, the command collects all input and emits the first N bytes.

type HeadLines

type HeadLines int

HeadLines sets the number of lines to output. Default: 10.
