| Mmm. Comparing the unix command line with MS-DOS is like comparing a
| dinky toy to the real thing. Both have four wheels. Only one gets you
| moving.
<snip>
| You'll have to stop comparing Win95 and X-Windows. They may have the
| same look but they're totally different in everyday use.
|
| With win95, you can manage your system and all applications with
| point-click-drag. You use your mouse for everything, occasionaly
| typing in a name or number of something. That is, the GUI is
| everything and the keyboard is just an appendix.
|
| Linux is the other way round. Your shell is holy and the GUI is just
| an appendix. Totally different.
Mmmm... gotcha. Comparing the two OSs (Oses? Ozs? OS's? I give up!) is a
faulty analogy.
Speaking of shells...
Linux seems to be using the "Bourne Again Shell", aka "bash", by default,
but also seems to have the C shell installed, and possibly the Korn shell
somewhere, I think...
"Unix Shells By Example: The guide to the C, Bourne, and Korn Shell, Awk,
Sed, and Grep" by Ellie Quigley (C) 1997 that the shell is the interface
between the user and the "kernel", the "heart" of the OS, loaded into
memory, at boot time, and when you type in commands, the shell parses the
command line, handle the wildcards, pipes, and job control, searches for
the command, and executes it. The Borne shell was based on Algol, and was
first made by AT&T. It does mention that the Korn shell, named after the
creator, David Korn, runs not only on Unix, but OS/2. Korn is a a superset
of Bourne.... hrm... but it doesn't seem to mention where the Bourne Again
Shell came from...
The book does seem to be quite technical... but seems to be laid out
nicely, as long as you don't really skim the paragraphs...
Funny... when using command line interfaces, never really gave much thought
on how the little prompt appeared on the screen ;}
