stream-tail

Emits the last few chunks of input

Example

const
    split2 = require("split2"),
    join = require("join-stream"),
    tail = require("stream-tail");

// Simple implementation of tail(1)

if (process.argv.length !== 3) {
    console.error(`Usage: tail NUMBER`);
    process.exit(1);
}

process.stdin
    .pipe(split2())
    .pipe(tail(process.argv[2]))
    .pipe(join("\n", { end: true }))
    .pipe(process.stdout);

Methods

tail(count)

Return an object stream that emits no more than the final count 'data' chunks of its input. Where the input contains fewer than count chunks, all chunks are emitted.
