| Hi All,

| I'm trying to write my first RedHat/Fedora-style startup script (no

Congrats.  Writing your own startup scripts is definitely graduating
from one grade to the next!  No flames here.

| database is started up and/or shutdown, so I do "> /dev/null 2>&1". I've
| seen this is several scripts, and I thought this would work, but it does
| not -- the response messages are still displaying. I think I may have
| misunderstood the purpose of "> /dev/null 2>&1". Can someone tell me
| what this is supposed to do, and how I can properly suppress messages?

The "&" has to come after the redirections.

| #!/bin/bash

| # Cloudscape startup script - Version 0.0.1

| # chkconfig: 345 95 05

| # description: Script for starting/stopping Cloudscape

| # processname : cloudscape
|
| # NOTES:
| #
| # This script is specifically for Fedora Core systems.
