    Quick scripting question

    Hey,
    I'm trying to setup Knoppix on USB with a few servers running on boot. I've googled the hell out of this and have found many ways of doing it, but only Knoppix.sh seems like it has a chance of working. At this point I think I must be asking the wrong questions.

    At any rate my knoppix.sh has the following code:

    /etc/init.d/ssh start
    /etc/init.d/webmin start
    /etc/init.d/mysql start
    /etc/init.d/apache2 start

    The output is:

    Usage: /etc/init.d/ssh {start|stop|reload|force-reload|restart|try-restart|status}.
    Usage: /etc/init.d/webmin { start | stop | restart }
    Usage: /UNIONFS/etc/init.d/mysql start|stop|restart|reload|force-reload|status
    Usage: /etc/init.d/apache2 {start|stop|graceful-stop|restart|reload|force-reload|start-htcacheclean|stop-htcacheclean|status}.

    Why is it not seeing the 'start' at the end?

    Thanks,
    --Yel

    I can't see any error in your /mnt-system/KNOPPIX/knoppix.sh. I tried this myself with /etc/init.d/ssh start and everything worked fine. How did you create that file? What version of Knoppix do you use?

    However I would place all services I like to start during boot in the file /etc/rc.local.

    Solved

    SOLVED

    I created knoppix.sh with notepad in Windows. This caused hidden characters to be generated.

    Check these and compare the results:
    Code:
    file <your_script>
    cat <your_script>
    cat -A <your_script>

    The results from above:

    Code:
    # file knoppix.sh
    knoppix.sh: Bourne-Again shell script text executable
     
    # cat knoppix.sh
    #!/bin/bash
    /etc/init.d/ssh start
    /etc/init.d/webmin start
    /etc/init.d/mysql start
    /etc/init.d/apache2 start
     
    # cat -A knoppix.sh
    #!/bin/bash^M$
    /etc/init.d/ssh start^M$
    /etc/init.d/webmin start^M$
    /etc/init.d/mysql start^M$
    /etc/init.d/apache2 start^M$
    ^M$

    That's why all those ^M's show up when you `cat -A`.
    vi doesn't create these files by default but if you open one
    for editing, vi will go with the flow.

    Strip out the extraneous Carriage Returns (0x0d) like this:
    Code:
    mv knoppix.sh knoppix.sh.CRLF
    cat knoppix.sh.CRLF | tr -d '\r' > knoppix.sh

    I'm using Knoppix 6.4.3 on flashdrive with a persistent image. I'd love to do it the "correct" way, but have had issues getting it to work.
    Tried init-rc.d, webmin, and 3 other ways, but none of them worked even if the text I added persisted through the reboot. I'm obviously missing something here, but I don't know what. For now, it works.

    However, I don't remember if I added the lines to rc.local. Not sure how I missed that. Thanks for the info. I'll need it soon enough.
