Linux Programming Essentials

I was just thrust into Linux programming (Red Hat) after several years of C++ on Win32. So I am not looking for the basics of programming. Rather I am looking to get up to speed with things unique to the Linux programming world, such as packages, etc. In other words, I need to know everything in https://www.redhat.com/courses/rhd251_red_hat_linux_programming/details/ without spending 3K. Any ideas of how I can acquire that knowledge quickly (and relatively cheaply)?

Update: The things that I am used to doing on Windows like building .exe and dlls using VC++, creating install scripts etc are just done differently on Linux. They use things like yum, make and make install, etc. Things like dependency walker that I take for granted in the windows world constantly send me to google while doing linux. Is there a 'set' of new skills somewhere that I can browse or is this more of a learn as you go?

The primary problem is this: As a very experienced programmer in Windows,I am having to ask simple questions like what's the difference between usr\bin and usr\local\bin and I would like to be prepared.

Edited because I had to leave a meeting when I originally submitted this, but wanted to complete the information

Half of that material is learning about development in a Unix-like environment, and for that, I'd recommend a book since it's tougher to filter out useful information from the start.

I'd urge you to go to a bookstore and browse through these books:

  • Advanced Programming in the Unix Environment by Stevens and Rago - this book covers threads, networking, IPC, signals, files, process management
  • Unix Network Programming, Volume 1 by Stevens - This book is focused on network programming techniques, design - you might not need this until much later

  • Unix/Linux System Administration - This book covers the more system administrator side of stuff, like directory structure of most Unix and Linux file systems (Linux distributions are more diverse than their Unix-named counterparts in how they might structure their file system)

    Other information accessible online:

  • GCC Online Manual - the comprehensive GNU GCC documentation

  • Beej's network programming guide - A really well written tutorial to network programming with the use of the BSD API. If you have done work with winsock, this should be mostly familiar to you.
  • Red Hat Enterprise Linux 5's Deployment Guide - talks specifically about Red Hat EL 5's basic administrative/deployment, like installing with package manager, a Red Hat system's directory structure...
  • make - Wikipedia article that will have links to the various make documentation out there
  • binutils - These are the Linux tools used for manipulating object/binaries.
  • GNU Build System - Wikipedia article about the traditional build system of GNU software, using autoconf/automake/autogen

Additionally, you will want to learn about ldd, which is like dependency walker in Windows. It lists a target binary's dependencies, if it has any.

And for Debugging, check out this StackOverflow thread which talks about a well written GDB tutorial and also links to an IBM guide.

Happy reading.

A good source is the Advanced Linux Programming book.

It's free and covers a lot of you are looking for

For POSIX and such I can recommend Advanced Programming in the UNIX Environment and having a bookmark to The single UNIX Specification.

For GCC/GDB and those tools I'm afraid I can't give you any good recommendation.

Hope that helps anyway.

Edit: Duck was slightly faster.

that is quite a large and diverse topic list. for the programming part i think the C++ library should be portable, things that are not should be documented. for the linux-admin part, i suggest you try to use linux as your main desktop system, as many notions are absorbed via day to day work, there is no magic tutorial

The single most important thing you'll need is a 99 cent notebook titled "Sys Admin" kept next to your computer. Keep track of everything you install/update including directory location, date, and method.

Thats a bit broad.
What kind of programs are you going to be doing? If you stick to standard c++ you're good to go... and just man everything else.
