Det första Unix-systemet skrevs i assembler av Ken Thompson på en Digital PDP-7 år 1969 efter att utvecklingen av operativsystemet Multics lagts ner. Namnet Unix valdes för att driva med Multics, som var avsett för flera användare. Efter Thompsons första version skrev han och Ritchie tillsammans unix2dos (sometimes named todos or u2d) is a tool to convert line breaks in a text file from Unix format (Line feed) to DOS format (carriage return + Line feed) and vice versa. When invoked as unix2dos the program will convert a Unix text file to DOS format, when invoked as dos2unix it will convert a DOS text file to UNIX format.

Unix is a family of multitasking, multiuser computer operating systems that derive from the original AT&T Unix, whose development started in the 1970s at the Bell Labs research center by Ken Thompson, Dennis Ritchie, and others. Initially intended for use inside the Bell System, AT&T licensed Unix to outside parties in the late 1970s, leading to a variety of both academic and commercial Unix variants from vendors … Unix is a portable, multitasking, multiuser, time-sharing operating system (OS) originally developed in 1969 by a group of employees at AT&T. Unix was first programmed in assembly language but was reprogrammed in C in 1973. Unix has been ported to more machine families than … Parameters. $0 => Command-name $# => contains the number of parameters for this shell is started $1 $2 => parameter 1 parameter 2 $?

it gives a little insight in UNIX and how things worked on PC 1985. Yet the view on the system itself is rather fast and does not present any deep insights. I way quite amused of the way the commands in the shell are presented; you could hardly see something. But it is a good video, shwoing how Unix was used in 1985.

The 2 denotes standard error (stderr).
