Documentation about lsyncd HOT 6 OPEN

I could not reproduce this error. Please provide more info like your exact 
configuration script, the debug/error log and what `ls -al /bin/sh' yields. I 
changed the example tough so it should now be compatible with 'dash' which is 
the default shell on my system.

configuration file:
settings = {
        nodaemon = true,
}

bash = {
        delay = 0,
        maxProcesses = 3,
        onCreate = "echo creat ^sourcePathname ^targetPathname",
        onModify = "echo mod ^sourcePathname ^targetPathname",
        onDelete = "echo del ^targetPathname",
        onMove   = "echo move ^o.targetPathname ^d.targetPathname",
--        onStartup = [[if [ "$(ls -A ^source)" ]; then cp -r ^source* ^target; 
fi]],
}

sync{bash, source="/home/lonewolf/teste1", targetDir="/home/lonewolf/teste2"}

ls -al /bin/sh
lrwxrwxrwx 1 root root 4 Jan 25  2011 /bin/sh -> bash


a simple touch /home/lonewolf/teste1/test triggers the error

The call should be 

sync{bash, source="/home/lonewolf/teste1", target="/home/lonewolf/teste2"}

not targetDir.

Sorry it doesn't complain more early

BTW direct operation is now built into Lsyncd already as 'default.direct'.

Its working now, in my opinion you should put a complete example for each 
layer, it would make it easier for who is starting to use it.

will do.
