- I remember reading about someone saying what UNIX needs to survive in
- the next decade.
-
- The one about a "more powerful command-line" was probably an unqualified
- statement.
-
- First, what is meant by it? What's powerful? I particularly find the UNIX
- prompt an excellent place to get my work done. In fact, one of the
- biggest complaints about UNIX is that the command-line is TOO powerful.
-
- A user can mistakenly wipe out their entire directory in one line! A
- user can clobber their files if they misuse shell metacharacters like
- "*" when using an "mv" command.
-
- For commands which are extremely long, command-line editing provided by
- "ksh" or "bash" makes substitutions and corrections a snap.
-
- With UNIX, I can move entire filesystems with a command line. I can have
- mountable file systems and I can access files over the network. All of these
- features I find extremely powerful and easy to use. Furthermore, they
- don't require 40 disk installations of Novell! Networking is built in!
-
- Software development is great. I have access to great compilers and debuggers
- from the Free Software Foundation. I don't know about you, but I'd
- prefer NOT to reboot my machine everytime I accessed guarded memory. With
- UNIX, you get a core dump and you can step through a debugger to see what
- happened. Isn't a protected system great?
-
- Obviously, there are problems with UNIX. For one, the hardware requirements
- are pretty high. Furthermore, it's not easy to learn. Commands are
- abbreviated because when it was invented, people were typing on mechanical
- terminals that required 5lbs. of pressure for key presses (exaggeration)!
-
- Without turing this into a flame-fest, before you get on the net and flame
- UNIX, why don't you do your homework first.
