Shellflow

Shell-native, agentless remote automation over ssh — concurrently, idempotently, and much faster than Ansible. Use when the user wants to run commands or deploy files across one or more servers from a plain Bash script annotated with `# @` comment directives, without installing any agent on targets. Triggers: "deploy", "run on servers", "run this across hosts", "ssh automation", "remote exec", "copy files to servers".

# shellflow — shell-native remote automation

shellflow is a shell-native, agentless automation tool that runs commands over
ssh - concurrently, idempotently and 10x faster than ansible.

The input is a **plain Bash script** whose blocks are delimited by `# @`
comment directives. `bash deploy.sh` runs the file unchanged; `shellflow`
drives the blocks: local execution, rsync/scp file copies, and concurrent
remote execution over the host's login shell (`ssh host bash -l -s` /
`zsh -l -s`, probed once per run, with the rc-extended login PATH injected
into each payload so toolchain PATHs resolve as in a manual `ssh host`).
Targets only need `bash`.

## When to use

Reach for `shellflow` (instead of hand-rolling parallel ssh loops, or pulling
in Ansible) when the task is:

- running the same read-only or confined command across several hosts
  (`uname`, `df`, `date`, service status, …),
- shipping a file/artifact to hosts and then acting on it,
- a deploy pipeline: local build → copy artifact → remote restart,
- anything that fits a linear sequence of local/remote/copy blocks.

It does **not** manage persistent config state (no facts/state engine), does
not install agents, and is not a CMDB. Use plain Bash (`if`, `for`,
`[ -f ] ||`, `command -v`) for control flow inside blocks.
