The best thing you can do to learn this is to find problems and solve them. Go through this site, look at all the "How do I do X in awk/sed/grep/etc." and try them for yourself before looking at the answers. Look if you get stuck or to see how others did it once you find a way. If you find yourself doing something repetitive in the terminal, stop and think about how you might use one or more utilities to make it easier. If you can't find a way to do it, post here and we'll guide you. |

The Unix Programming Environment by Kernighan and Pike is the classic on the topic. It's ancient but still in print, which should tell you something. The Art of UNIX Programming by esr is much newer. I found it interesting and helpful, but with a bit more "advocacy" than I felt was necessary. (Euphemism for "frothing partisanship.") Be prepared to take his comparisons to other OSes with a grain of salt, as I recall finding outdated[1] material even when the book was new, and the *ix competitors have almost a decade of progress since that time. [1] Mostly, I recall jabs at weaknesses in non-*ix OSes that had been eliminated before the book was published. The same sort of thing you find in amateur Windows vs Mac vs Linux arguments all over the net. |

Follow the one-a-day plan. Start by listing everything in But the important thing is that you will learn something new every day, and probably before you are half way through, you will understand so much of the basics, that you can easily pick up half a dozen new commands per day. But you have to use them, each and every one of them, even if it is only tinkering and doing exercises with them. |

Programmers have a unique opportunity to master Linux. Every chance you get, instead of writing a program to accomplish a task write a shell script to do it. I actually have a standing personal challenge to write everything in Bash before I write a program - you'd be amazed and disturbed. As far as a recommendation for a book, it might seem silly, but the Linux Pocket Guide has a place of honor on my bookshelf. It is compact and has loads of useful Linux programs. Perusing it is easy and its a great reference. |

gives you a big list of useful commands, grouped by context. You can take this as a guide and learn one command a day, and of course as a repository to search in. |

I would add Linux® Command Line and Shell Scripting Bible by Richard Blum. It'easy to understand, practical and full of many useful examples. |
