Linux是一类Unix盘算机操作体系的统称。Linux操作系统也是自在软件跟开放源代码发展中最有名 的例子。在1991 年的十月,由一个名为 Linus Torvalds的年青芬兰大学生带头开发的功课系统。

历史背景Linux先容Linux的组成Linux的长处 历史背景 1991 年的十月,当初网际网路还不像当初这么普遍,上网的人大局部都附属于一些研讨机构,或者是大学里面的学生、 教学,1991年10月5日, 上午11时53分,有一个名为 Linus Torvalds 的年轻芬兰大学生在 comp.os.minix 这个消息群组上发表了这样一个帖子,它标记着linux的诞生了: Do you pine for the nice days of minix-1.1, when men were men and wrote their own device drivers? Are you without a nice project and just dying to cut your teeth on a OS you can try to modify for your needs? Are you finding it frustrating when everything works on minix? No more all- nighters to get a nifty program working? Then this post might be just for you :-) As I mentioned a month(?) ago, I'm working on a free version of a minix-lookalike for AT-386 computers. It has finally reached the stage where it's even usable (though may not be depending on what you want), and I am willing to put out the sources for wider distribution. It is just version 0.02 (+1 (very small) patch already), but I've successfully run bash/gcc/gnu-make/gnu-sed/compress etc under it. Sources for this pet project of mine can be found at nic.funet.fi (128.214.6.100) in the directory /pub/OS/Linux. The directory also contains some README-file and a couple of binaries to work under linux (bash, update and gcc, what more can you ask for :-). Full kernel source is provided, as no minix code has been used. Library sources are only partially free, so that cannot be distributed currently. The system is able to compile "as-is" and has been known to work. Heh. Sources to the binaries (bash and gcc) can be found at the same place in /pub/gnu. ALERT! WARNING! NOTE! These sources still need minix-386 to be compiled (and gcc-1.40, possibly 1.37.1, haven't tested), and you need minix to set it up if you want to run it, so it is not yet a standalone system for those of you without minix. I'm working on it. You also need to be something of a hacker to set it up (?), so for those hoping for an alternative to minix-386, please ignore me. It is currently meant for hackers interested in operating systems and 386's with access to minix. The system needs an AT-compatible harddisk (IDE is fine) and EGA/VGA. If you are still interested, please ftp the README/RELNOTES, and/or mail me for additional info. I can (well, almost) hear you asking yourselves "why?". Hurd will be out in a year (or two, or next month, who knows), and I've already got minix. This is a program for hackers by a hacker. I've enjouyed doing it, and somebody might enjoy looking at it and even modifying it for their own needs. It is still small enough to understand, use and modify,

If your efforts are freely distributable (under copyright or even public domain), I'd like to hear from you, so I can add them to the system. I'm using Earl Chews estdio right now (thanks for a nice and working system Earl),
接触性皮炎, and similar works will be very wellcome. Your (C)'s will of course be left intact. Drop me a line if you are willing to let me use your code. Linus PS. to PHIL NELSON! I'm unable to get through to you,

泡茶,Linux 系统中常用的系统程式大部份是美国自由软体基金会 (Free Software Foundation) 开发出来的软体,而且也有不少机构或个人为 Linux 开发应用程式,这些程式一样大多都是自由软体,任何人都可免得费的在网路上获得,不外自行去取得这些程式再 逐一安装十分不便,於是有些公司或集团就会去收集、整合 Linux 上的程式,把「核心-系统程式-运用程式」总合起来形成一个完整的作业系统,让正常应用者能够简便的安装完全个系统,这就是所谓的「装置套 件」(distribution),咱们一般讲的 Linux 系统便是针对这些安装套件而言,同样是 Linux 系统,却分成不同公司、机构整合出来的不同安装套件,这就是大家经常在网路上看到 Linux 有那么多「种」的起因。Linux的优点 Linux 存在 Unix 系统的程式介面跟操作方法,也继续了 Unix 稳固有效力的特色。网路上安装 Linux 的主机持续运做一年以上而未曾当机、不用关机是稀松平凡的事,不过 Linux 却不像普通 Unix 要累赘宏大的版权费用,也不需要在专属的昂贵硬体上才可以使用;Linux 可以在个别的 i386 PC 上执行,效力又高,
