Processes and System

Run commands safely

run(["git", "log", "--oneline"], { timeout: 5s })
    |> stdout_lines
    |> take(10)
    |> print

run passes argv directly and does not invoke a shell. Options include cwd, env, stdin, timeout, and max_output; stdout_lines exposes output as a lazy line stream.

System data

• processes: a stream of process snapshots
• system: OS, architecture, CPU, and memory metadata
• env: a read-only view of environment variables
• shell: explicit shell semantics, separate from run
