. The question is Why are UNIX commands noninteractive and why is their output not usually preceededby header information? This question has been driving me insane for an hour now please help From my understanding, Unix was developed as a primarily server operating system. Thus programs had to be developed to run non-interactively, as user interactivity may not always be possible. Due to the amount of options and use of piping i guess the use of headers in most unix programs would be useless. For example, if you run dmesg on a system it doesn't print any headers... as there are so many different kinds of hardware and messages displayed, headers would be useless as they wouldn't always be accurate.
Most system administrators create their own scripts to deal with certain output files and mangle them in a way that is infromative and useful to them.
That's a stinker of a question you've got.
