I'm trying to build a Synergy AutoStart script as per this article, the shell is giving me the error

Syntax Error

Expected end of line, etc. but found unknown token

Here is the script I'm working on...

#!/bin/sh
. /etc/rc.common

run=(/usr/local/bin/synergyc -n $(hostname -s) -1 -f 192.168.0.108)

KeepAlive ()
{
 proc=${1##*/}

 while [ -x "$1" ]
 do
  if ! ps axco command | grep -q "^${proc}\$"
  then
   "$@"
  fi
   sleep 3 
 done
}

StartService ()
{
 ConsoleMessage "Starting Synergy"
 KeepAlive "${run[@]}" &
}

StopService ()
{
 return 0
}

RestartService ()
{
 return 0
}

RunService "$1"

And when the error is thrown, the "period" is highlighted on this line . /etc/rc.common

Is there something I'm missing here?
