Is there a command that list all enabled Apache modules?

If want to check if a process is running and start it if not. My script below is buggy and always says that a process is running. What is wrong?

$ ./check_n_run thisisnotrunning
./check_n_run: thisisnotrunning is already running

Here is the script:

$ cat check_n_run

#!/bin/sh

USAGE="usage: $0 processname"
if [ $# -ne 1 ] ; then
        echo "$USAGE" >&2
        exit 1
fi

ps ax | grep -v grep | grep $1> /dev/null
if [ $? -eq 1 ]
then
  echo "$1 not running"
  # start here      
else
  echo "$0: $1 is already running" >&2
fi

exit 0
