unintentionally left blank oops! 10 LPI 101 Course Notes 1 Foreword 1 Foreword A is for awk, which runs like a snail, and B is for biff, which reads all your mail. C is for cc, as hackers recall, while D is for dd, the command that does all. E is for emacs, which rebinds your keys, and F is for fsck, which rebuilds your trees. G is for grep, a clever detective, while H is for halt, which may seem defective. I is for indent, which rarely amuses, and J is for join, which nobody uses. K is for kill, which makes you the boss, while L is for lex, which is missing from DOS. M is for more, from which less was begot, and N is for nice, which it really is not. O is for od, which prints out things nice, while P is for passwd, which reads in strings twice. Q is for quota, a Berkeley-type fable, and R is for ranlib, for sorting ar table. S is for spell, which attempts to belittle, while T is for true, which does very little. U is for uniq, which is used after sort, and V is for vi, which is hard to abort. W is for whoami, which tells you your name, while X is, well, X, of dubious fame. Y is for yes, which makes an impression, and Z is for zcat, which handles compression. – THE ABC'S OF UNIX /usr/share/games/fortune/songs-poems This course material is based on the objectives for the Linux Professionals Institute’s LPI 101 examination (specifically, release 2 of the objectives). The course is intended to provide you with the basic skills required for operating and administering Linux systems. At every good training course the student should come away with some paper in his hand, to file in the company filing cabinet. A really excellent course will include some knowledge and practical ability in the student's head as well. We hope to achieve at least the first with these notes. The second is up to the instructor. Goal of this course This course aims to equip you with the knowledge to be able to pass the LPI 101 examination
