If you are interested in the history of Linux, you should start from UNIX.
After dropped out of the project Multics by AT&T, the new operating system UNIX implemented by Ken Thompson and Dennis Ritchie at AT&T Bell Lab in 1969 and the first release of UNIX came out in 1970. Later they rewrote it in C programming language to make it portable.
Linus Torvalds announced about his Linux kernel project at Usenet posting to the newsgroup “comp.os.minix” on 25th August 1991.
Hello everybody out there using minix-
I’m doing a (free) operating system (just a hobby, won’t be big and professional like gnu) for 386(486) AT clones. This has been brewing since April and is starting to get ready. I’d like any feedback on things people like/dislike in minix, as my OS resembles it something (same physical layout of the file-system (due to practical reasons) among other things).
I’ve currently ported bash(1.08) and gcc(1.40), and things seem to work. This implies that I’ll get something practical within a few months, and I’d like to know what features most people would want. Any suggestions are welcome, but I won’t promise I’ll implement them
PS. Yes – it’s free of any minix code, and it has a multi-threaded fs. It is NOT portable (uses 386 task switching etc), and it probably never will support anything other than AT-harddisks, as that’s all I have
According to Torvalds, Linux gets importance in 1992 when the X Window System was ported to Linux by Orest Zborowski, which enable GUI feature in Linux first time.
Nowadays, Linux is the most popular operating system, and most of the operating systems are designed on Linux kernel only.
