Apero.Proc (Apero v3.0.0)

Copy Markdown View Source

Process and executable utilities for Apero (pure-Elixir subset).

Provides helpers for checking command availability, finding executables, and VM introspection. All functions are pure Elixir/Erlang — no shell execution involved.

For shell-based operations (process listing, signalling, logs, lsof, fuser) see Trebejo.Proc.
