# shep
The `shep` binary. [shep](https://github.com/TurtIeSocks/shep) is a process
manager written in Rust: one binary runs a daemon called the shepherd, which
keeps a flock of your long-running processes alive, captures what they print,
and says plainly when something is wrong.
It runs on macOS and Linux. On Windows every command prints `shep does not yet
support Windows` and exits 1, which is a real answer but not a useful one.
Write a `Flockfile.toml`. Two fields is a complete one:
```toml
[[app]]
name = "web"
script = "./server"
```
Then start it. You never launch the daemon yourself, because `shep start`
notices nothing is listening and re-execs itself in the background.
```console
$ shep start Flockfile.toml
$ shep ls
ID NAME STATUS PID RESTARTS CPU MEM UPTIME FOLD
1 web online 1001 1 12.5% 48.1M 1m backend
2 worker online 1002 2 12.5% 48.1M 2m backend
```
`shep bleats` follows the logs, and `shep logs` is the same command for people
who prefer the boring word. Every themed verb has a straight alias that works
forever. Everything renders as `--format json` too, under a versioned
envelope, so you can pipe it somewhere without scraping columns.
`shep import` reads a real pm2 dump and writes a Flockfile out of it.
This crate builds three binaries, not one: `shep` itself, plus
`shep-runtime` and `shep-dev` — thin wrappers that prepend `runtime` and
`dev` before parsing, for use as a container `ENTRYPOINT` (`shep runtime` and
`shep dev` work identically through the `shep` binary; the aliases exist so a
container image needs no shell to supply the verb). `cargo install shep`
installs all three.
Embedding shep in another program is [`shep-client`](https://crates.io/crates/shep-client)'s
job, not this crate's — `shep` exposes nothing beyond its three `main*`
entry points, each of which owns the whole process (exit code, `argv`, signal
handling) the way a CLI is expected to.
The repository README has the full lexicon, what works today, and what is not
built yet. shep is pre-release: no tagged release, and several v1.0 items are
still missing.
