Topic: BASH Shell Programming and The Ubuntu UPSTART Init Daemon



Because the traditional System V init daemon (SysVinit) does not deal well with modern hardware, including hotplug devices, USB hard and flash drives, and network-mounted filesystems, Ubuntu replaced it with the Upstart init daemon. The runlevel-based SysVinit daemon uses runlevels (recovery/single-user, multi-user, and more) and links from the /etc/rc?.d directories to the init scripts in /etc/init.d to start and stop system services. The event-based Upstart init daemon uses events to start and stop system services.


The bash (Bourne-Again) Shell is based on Bourne Shell and has many enhancements drawn from the Korn and C Shells. It was developed by the GNU Project and is widely used on UNIX-like systems. It is useful both as an interactive shell and a high-level programming language.

(see above)


Addison-Wesley Professional/Prentice Hall PTR, and O'Reilly have been kind enough to provide us with review copies of some of their books, which we will continue to raffle off as giveaways at our meetings. The publishers always ask that the persons receiving the books provide a review and/or feedback about their books.

Unigroup would like to thank both companies for the support provided by their User Group programs.

As always, all of the books will be available for review at the start of the meeting.

We have some Solaris Related CD-ROMs from our friends at the local NYC Sun Microsystems Office.

       ! Students: We are looking for proof that you are
         currently enrolled in classes (rather than working
         full-time), and as such, your Student ID should show
         a CURRENT date.  We have been presented Student IDs
         containing NO dates whatsoever, and in the
         current environment, perpetual/non-expiring access
         to university facilities just does not feel right.
         If your ID contains no date, please bring
         additional proof of current enrollment.  Thanks.
