Yuk! 'batch file'? '.bat'? While perfectly fine, far too many bad
memories conjured up by that name choice; use 'script' and '.sh' or no
extension . . . ;-) I was quite adept at that crippled system and, over
the course of several years, had perfected a batch file system that
enabled me to edit, compile, link and perform other programming tasks
on any of my projects in MS-DOS, NDOS and Real/32 with a minimum of
typed commands -- it spanned 30+ batch files and close to 2000 lines.
While it worked, and worked well, I can do virtually the same thing in
Linux just by using emacs or a few, small scripts . . . :-)

First of all, are you *sure* that '/etc/init.d/Apache2' and
'/etc/init.d/MySQL' exist in that dir with that exact capitalization?
If so, then you need to fix the script above. I was apparently not
clear enough about the 'echo...' commands just being place holders for
demo purposes. Try this instead:

su --login root -c '/etc/init.d/Apache2 start ; /etc/init.d/MySQL start'

These commands have to all be on the same line; putting them *after*
the line containing the 'su...' effectively keeps them from working. If
you really want user feedback in the form of echo commands (and
possibly other things), then create a script containing all you want to
do and substitute it for the above line like so:

    su --login root -c /home/username/bin/nameOfBigScript

assuming 'nameOfBigScript looks something like this:

   #!/bin/bash
   echo Starting apache2
   /etc/init.d/Apache2 start
   echo Starting mysql
   /etc/init.d/MySQL start

and you've done a:

   chmod a+x /home/username/bin/nameOfBigScript

I'm pretty sure I said to *not* include the dashed lines . . . :-D
