My bash script is getting an argument but I didn't put any argument : ###My objective is to make a bash script service that creates a file when the runlevel is 5 and delete that file when the runlevel is 3. 
###The problem that I got is when i got to runlevel 3 . I get :

> The current lvl is : 3 and number of arguments is : 1  I am at line 10
> . The command is start

####Why it's getting start argument and I didn't pass any argument.
####I can make the script work fine if I remove the test condition on the number of arguments and let the script just delete the file when it's at lvl 3 
but the thing that it tells me that the number of argument is 1 and it starts doesn't enter my mind. I have already done much research and I didn't find any solution.

    #! /bin/bash
    # chkconfig: 35 99 01
    # description : some startup script
