click-extra trail - Trace a simulated batch of operations behind an operation trail.

click-extra trail [OPTIONS]

Trace a simulated batch of operations behind an operation trail.

Roasts a handful of make-believe vegetables (each a short pause, the leeks scorching) and reports them as they land. The display follows the batch: with --jobs 1 each outcome echoes as a plain line; with two or more jobs a spinner carries the running tally while outcomes stream above it; --progress-bar swaps that spinner for a determinate progress bar. Add --time to append each vegetable's roast time and the batch total; --elapsed and --eta turn that on too, counting up from zero or down as an estimate. Honors --progress / --no-progress and stays silent off an interactive terminal.

Drive the batch with a determinate progress bar instead of a spinner.
For --progress-bar, show the time remaining (--eta) or elapsed (--elapsed); either one turns timing on, like --time. A spinner always shows elapsed time.
Aggregate spinner animation for concurrent runs (see the spinner command for names). Defaults to the built-in spinner; ignored with --progress-bar.
