Maybe I'm misunderstanding you, but I don't understand this approach. |

If the daemon is not running there's nothing in the fifo. Why got to all the |
10 |
complexity of writing an independent program that checks if something is |
11 |
running then does various actions? The script necessarily depends on the |
12 |
daemon running so instead of checking if it is, simply have the daemon start |
13 |
the script. No daemon running = no script launched = no complexity. |

The script will simply accept what is it is given, no complex checks needed. |

Seeing as the input is from a logger, chances are you are inserting logs to a |
17 |
db, or launching a log analyser, right? Modern loggers support launching child |
18 |
scripts as a matter of routine. |

If I'm still off-bat and this approach cannot work for solid technical |
21 |
reasons, then I'll go away and shut if if you say so :-) |
