Question

I have a script that I’m making to use to start/stop/etc a JBoss AS (v7.1.1). I’m running on SUSE Enterprise 11, so the provided initscript doesn’t work. The problem I’m running into with my script is that the cleanup function is never called.

#!/bin/sh

HOME="/var/rulesserver"
CURRENT=$HOME/logs/current
LOGFILE=$HOME/logs/`date -u +%Y-%m-%d-%H-%M-%S`.log
COMMAND=/usr/local/jboss/bin/standalone.sh
SELF=/usr/sbin/jboss-as-standalone

function cleanup() {
    rm $CURRENT
}

function run() {
    trap cleanup 1 2 3 6 15
    nohup $COMMAND &> $CURRENT
}

case $1 in
    "start" )
        echo "Starting the server..."
        if [ -e $CURRENT ]
        then
            echo "ERROR: The server is already running"
        else
            ln -s $LOGFILE $CURRENT
            run &
            echo "Server started"
        fi
        ;;
    "stop" )
        echo "Stopping the server..."
        killall java
        echo "Server stopped"
        ;;
    "status" )
        if [ -e $CURRENT ]
        then
            echo "The server is currently running"
        else
            echo "The server is currently stopped"
        fi
        ;;
    "cleanup" )
        cleanup
        ;;
    "restart" )
        $SELF stop
        $SELF start
        ;;
    * )
        $SELF start
        ;;

I may be confused, but can you not just do

function run() {
    ( nohup $COMMAND ; rm $CURRENT )
}

?

$COMMAND would block till i dies and then there would be an rm and then the subshell would exit? There would be no need for trap.
