How to Organise & Operate a Small Business in Australia: How to turn ideas into success - from Australia's leading small business writer

At some point in time, everyone who owns a computer will experience the trials and tribulations of hard drive failure.  The reasons behind it vary, and could include everything from a human error to damages resulting from flood or water.  Viruses can play a role as well, along with many other factors.  For many years, the need to recover data that has been lost or destroyed has made data recovery such a very valuable asset.

Almost all hard drives can be recovered.  Normally, if the drive is making a ticking or a scratching noise, you can use certain software programs to recover the data.  Sometimes, due to age or bad parts, the aperture arm in the hard drive can fail, or the platters can become damaged and lose the data that they hold.  If you can’t recover the information with software, you’ll need to send the hard drive off and have it either rebuilt or have technicians recover your data.

If you got problems with  your computer data, then this handbook will give you the smartest solution ever!

This book delivers what the title states: It describes the 101 most important UNIX and Linux commands and system calls.  The book bridges the gap between on-line tutorials and manual pages on one hand, and books of 1,000 pages or more that explore the nuances of many shell commands in exhaustive detail.  While most of these sources provide excellent information, they do not really solve the plight of the novice user, nor do they fully answer the questions that more experienced, and even expert, users often have.  Much of the complexity of UNIX and Linux, and much of the difficulty faced by users is caused by the extremely large and rich set of shell commands, many of which have a very large set of allowable options that, while useful in certain circumstances, often provide more frustration than help because of their complexity.  Many UNIX and Linux system calls are also complex, and have interactions that can be rather difficult for many programmers.

The many variants of UNIX cause additional difficulties.  Even Linux has multiple variants: there are often subtle differences in the Linux implementations by Red Hat (Fedora), Ubuntu, SUSE, and Debian.  For example, one of my recent senior students had a major project that required using a particular “Linux” software application containing a particular language’s character set and grammar.  The software would not work (indeed, it would not even install properly) on three of the most common Linux implementations!

Our approach is to focus on a smaller set of commands and system calls – the ones that are most important.  For each of these, only the most useful of the many options are described.

As a professor, I taught operating systems in general, and UNIX in particular, for over twenty-five years.  As the author of the book Advanced Topics in UNIX, which was selected as a main selection on UNIX by the Newbridge Book Club, and Advanced Topics in UNIX, Second Edition (available electronically on this ebook platform), I had to make choices in what I presented and how I presented it.  Finally, as an analyst/consultant on many different applications in multiple UNIX and Linux systems, I had to make choices based on the quality of the source code, and on its performance and maintainability.

I am confident that I have made the correct choices in selecting which of the many shell commands, system calls and options to discuss in this book and at what level they should be discussed.  I hope you agree.
