A small Go library wrapping os/exec.Cmd to run external commands safely in concurrent, asynchronous applications. It provides channel-based non-blocking execution, real-time stdout/stderr streaming, live status, and proper process termination.
Use cases
- run external commands asynchronously in Go
- stream stdout and stderr in real time from a subprocess
- start a long-running process and stop it later
- avoid race conditions when reading command output
- fire-and-forget command execution with a status channel
When to choose
- you need non-blocking subprocess execution with streaming output in Go
- you want safe, race-free reading of stdout/stderr while a command runs
- you need to start, monitor, and stop external processes concurrently
When to avoid
- you only need simple synchronous command execution with no streaming
- you are not working in Go
