drain's Introduction

Drain

Drain is a process manager like foreman.

Build and Test:

  $ ./bootstrap.sh

Usage

Create $HOME/.drainfile with the following schema (example):
```
process-name-1:color-number:group-name-1,group-name-2:command
process-name-2:color-number:group-name-1:command
# a comment
...
```
- process-name: the user defined name of the process
- color-number: terminal color number (0-255 if your terminal support 256 colors)
- group-name: simplifies starting a group of processes (only the server and up command supports groups)
- command: a bourne shell command
Start all processes with drain server.
