Wick-Init-D-Lib

Not all systems are created equally. In that regard, not all /etc/init.d/ environments are the same either. Instead of rewriting a shell that's extremely similar for multiple services, this formula will install a library that can be used to make init-style scripts quickly.

There are many hooks that you can plug into in order to run commands right before/after startup, shutdown and reloads. Just define a new function to override the old, empty one.

Examples

#!/usr/bin/env bash
# This is a sample `/etc/init.d` script that uses the library.

# Source in the init.d library
. /usr/local/lib/wick-init-d-lib

# This is the one function that MUST exist.  It starts the process.
# It takes two parameters: the log file and the PID file.
processStart() {
    # For this example, the command doesn't fork
    # Append all stdout/stderr to the log file
    /usr/local/bin/some-command >> "$1" 2>&1 &

    # Disown, which is similar to using "nohup"
    disown %+

    # Write the PID file
    echo "$!" > "$2"
}

# Before we start this command, let's wipe out its temporary data
startBefore() {
    rm -rf /tmp/some-command/
}

# This part is crucial.  After you define all of the necessary functions,
# you must call this one.  It handles the arguments and coordinates the
# calling of the right functions.
handleCommand

Returns nothing.
