Master the Linux instruments that would Make You a extra effective, potent Programmer

The Linux Programmer's Toolbox helps you faucet into the large choice of open resource instruments to be had for GNU/Linux. writer John Fusco systematically describes the main valuable instruments to be had on so much GNU/Linux distributions utilizing concise examples that you should simply alter to fulfill your wishes.

You'll commence by way of studying the fundamentals of downloading, construction, and fitting open resource tasks. you will then learn the way open resource instruments are disbursed, and what to seem for to save some time on initiatives that are not prepared for you. subsequent, you will examine the bits and bobs of construction your individual tasks. Fusco additionally demonstrates what to appear for in a textual content editor, and will even convey you a couple of new methods on your favourite textual content editor.

You'll increase your wisdom of the Linux kernel by means of studying the way it interacts together with your software program. Fusco walks you thru the basics of the Linux kernel with basic, thought-provoking examples that illustrate the foundations in the back of the working method. Then he indicates you ways to place this wisdom to take advantage of with extra complex instruments. He specializes in the best way to interpret output from instruments like sar, vmstat, valgrind, strace, and use it on your program; tips to make the most of numerous programming APIs to improve your individual instruments; and the way to put in writing code that displays itself.

Next, Fusco covers instruments that assist you increase the functionality of your software program. He explains the rules at the back of state-of-the-art multicore CPUs and demonstrates tips on how to squeeze the main functionality from those structures. ultimately, you are going to study instruments and methods to debug your code below any circumstances.

Coverage includes

  • Maximizing productiveness with editors, revision regulate instruments, resource code browsers, and "beautifiers"
  • Interpreting the kernel: what your instruments are telling you
  • Understanding processes–and the instruments on hand for handling them
