NO, do not delete them.

The 'shebang' is not actually a comment, it just looks like it.

The system looks at the first line of a script to determine what lang/shell its written in and runs that.

#!/bin/bash
means run the bash shell (prog) in /bin & pass this script to it

#!/usr/bin/perl
means run the perl prog in /usr/bin & pass this script to it

hte '#!' as a the first chars in line one are a special signal to the system


As for chkconfig, try

man chkconfig
especially the section 'RUNLEVEL FILES'
