  • Recompiling Minix
    8 RECOMPILING MINIX This chapter is intended for those readers who wish to modify MINIX or its utili- ties. In the following pages we will tell what the various files do and howthe pieces are put together to form the whole. It should be emphasized that if you simply intend to use MINIX as distributed, then you do not have torecompile the system and you do not have toread this chapter.Howev er, ifyou want to makechanges to the core of the operating system itself, for example, to add a device driverfor a streamer tape, then you should read this chapter. 8.1. REBUILDING MINIX ON THE IBM PC Although this section is specifically for IBM PC users, it should also be read carefully by everyone interested in recompiling MINIX.Most of what is said here applies to all versions of MINIX.The sections about other processors mostly discuss the differences between recompiling MINIX on an IBM PC and on another system. The MINIX sources are contained in the following directories, normally all subdi- rectories of /usr/src except for include which goes in /usr/include: center allbox; l l. Directory Contents include The headers used by the SEC. 8.1 REBUILDING MINIX ON THE IBM PC 113 commands (has twosubdirectories) kernel Process, message, and I/O device handling mm The memory manager fs The file system tools Miscellaneous tools and utilities test Test programs lib Libraries (has several subdirectories) commands The utility programs (has manysubdirectories) Some of the directories contain subdirectories. If you are working on a hard disk, be sure that all these directories have been set up, and all files copied there from the dis- tribution diskettes and decompressed and dearchived.

  • Linux Programming
    Linux & Shell Programming By High School Technology Services myhsts.org Session 3 Contents Text Editing Types of Editors Basic Editor Tasks with vi Editing Multiple Files Set Commands vi Startup File Types of Editors ed is a line editor for the Unix operating system. It was one of the first parts of the Unix operating system that was developed, in August 1969. Elvis is a vi/ex clone, i.e. it closely resembles the Unix text editor "vi", but adds quite a few commands and features. Elvis is written by Steve Kirkendall and is distributed under the Clarified Artistic License which is used by Perl and is a GPL-compatible free software license. Editing files using the screen-oriented text editor vi is one of the best ways. This editor enables you to edit lines in context with other lines in the file. An improved version of the vi editor which is called the VIM has also been made available now. Here, VIM stands for Vi Improved vi is generally considered the de facto standard in Unix editors because − It's usually available on all the flavors of Unix system. Its implementations are very similar across the board. It requires very few resources. It is more user-friendly than other editors such as the ed or the ex. Basic Editor Tasks with vi Basic Editor Tasks with vi Following is an example to create a new file testfile if it already does not exist in the current working directory − Basic Editor Tasks with vi Operation Modes While working with the vi editor, we usually come across the following two modes − Command mode − This mode enables you to perform administrative tasks such as saving the files, executing the commands, moving the cursor, cutting (yanking) and pasting the lines or words, as well as finding and replacing.

  • Reference Manual for the Minix 1.5 Demonstration Disk
    REFERENCE MANUAL FOR THE MINIX 1.5 DEMONSTRATION DISK ANDREW S. TANENBAUM Prentice Hall, Inc 2 Copyright 1991 Prentice Hall, Inc. 1 1 INTRODUCTION Every computer needs an operating system to manage its memory, control its I/O devices, implement its ®le system and provide an interface to its users. Many operating systems exist, such as MS-DOS, OS/2, and UNIX. This manual provides a very brief introduction to another operating system, MINIX. It is intended to accom- pany the MINIX demonstration diskette. Although MINIX was inspired by the well-known AT&T UNIX operating system, its design and implementation are completely new. It does not contain even a single line of AT&T code: not in the operating system, not in the C compiler, and not in any of the nearly 200 utility programs supplied with MINIX. For this reason, it is possible to include not only all the binary programs, but, virtually all the source code of the operating system and utilities as well. In this way, people can study MINIX in detail to learn how a modern operating system is constructed, and can also modify it to suit their own tastes if need be. Before getting started, we would like to point out that this manual and the accompanying demonstration diskette only deal with a tiny fraction of MINIX, just to give the ¯avor of the system. If your favorite feature (e.g., the Berkeley vi edi- tor) is not present here, that does not mean that it is also absent from the full sys- tem.

There is a simple notation that can describe the `shape' of files when the typical array-of-lines picture is inadequate. That notation is regular expressions. Using regular expressions to describe the structure in addition to the contents of files has interesting applications, and yields elegant methods for dealing with some problems the current tools handle clumsily. When operations using these expressions are composed, the result is reminiscent of shell
