Unix (officially trademarked as UNIX, sometimes also written as Unix with small caps) is a computer operating system originally developed in 1969 by a group of AT&T employees at Bell Labs, including Ken Thompson, Dennis Ritchie, Brian Kernighan, Douglas McIlroy, and Joe Ossanna. Today's Unix systems are split into various branches, developed over time by AT&T as well as various commercial vendors and non-profit organizations. The Open Group, an industry standards consortium, owns the “Unix” trademark. Only systems fully compliant with and certified according to the Single UNIX Specification are qualified to use the trademark; others may be called "Unix system-like" or "Unix-like" (though the Open Group disapproves of this term). However, the term "Unix" is often used informally to denote any operating system that closely resembles the trademarked system. During the late 1970s and early 1980s, the influence of Unix in academic circles led to large-scale adoption of Unix (particularly of the BSD variant, originating from the University of California, Berkeley) by commercial startups, the most notable of which are Solaris, HP-UX and AIX. Today, in addition to certified Unix systems such as those already mentioned, Unix-like operating systems such as Linux and BSD descendants (FreeBSD, NetBSD, and OpenBSD) are commonly encountered. The term "traditional Unix" may be used to describe a Unix or an operating system that has the characteristics of either Version 7 Unix or UNIX System V. From Wikipedia under the
GNU Free Documentation License How do i write a script to log into another unix machine? Q. I want to write a UNIX script that allows me to log into another UNIX machine automatically. What are the commands I need for this? Asked by Brooker J - Wed Jul 29 21:36:48 2009 - - 1 Answers - 0 Comments A. Hmmm. You are going to need to read in the responses. Look into "Expect", which is a language written just for this kind of thing, or Perl.

I do not want users to take ownership of files they create in a directory, I want the new file to inherit the permissions of the existing directory. Can't figure out in UNIX but got it in NTFS. Thanks again. Asked by james j - Tue Apr 27 00:27:44 2010 - - 1 Answers - 0 Comments A. Set the setgid bit on the directory - that is, chmod g+s the directory. That will cause new files to inherit the group ID of the directory. I don't think there's any way for new files to inherit the user ID on the directory though.

Q. For example, I want to create a void function, then put it into a separate object file. (.o) I want to have the main file as .c, then combine the main file and the object file into one .exe file in unix. How would I do this? Is there a certain code I need to write to tweak the code to tell the main to link to the object? Asked by sephrem99 - Tue Mar 23 00:59:04 2010 - - 1 Answers - 0 Comments A. On *nix platforms you usually compile programs with a makefile. If you are unfamiliar with makefiles hit Google to learn all you ever wanted to know about them. Here is a very short one: --- CORE = core.o ABOUT = about.o LIBS = libstdc+ program = test objects = $(CORE) $(ABOUT) .SUFFIXES: .o .cpp .cpp.o : gcc -c -o $@ $< all: test about test: $(PROGRAM) $(PROGRAM): ${OBJECTS} gcc -o $(PROGRAM) $(OBJECTS) $(LIBS) --- Now for the source members... about.hpp #ifndef ABOUT_HPP #define ABOUT_HPP extern "C"{ void display_dialog(char* version=0); } #endif There's nothing special about the "about.cpp" file, it just contains that display_dialog() function. Now lets look at the core.cpp file (there's nothing special… [cont.] Answered by Benny - Tue Mar 23 01:42:34 2010 From Yahoo Answer Search: "Unix" See also:
