Unix/Linux OS/Unix Korn Shell Scripting Question

Question
2)   What does the Korn shell history mechanism allow the user to do?

a)   See a historical record of users who have logged on to the machine
b)   Sort $HOME subdirectories in historical order
c)   Have access to, reuse, and edit previous commands
d)   Keep a history of when and for how long the user sessions have been
e)   See a history of the installation dates of versions of the Korn shell

Answer
The answer is:

It really doesn't matter -- we all use bash now!

Just kidding (but not really...)

The answer is "c"...

No-one really uses "ksh" since "bash" has the best of "ksh" and "csh" in it...
(unless they have an antique box they have to maintain... like a SCO/OS5 box...)

Enjoy!

Experience

I've been head of development at our company since 1984. Our OS's at that time were Point 4's IRIS and Altos' Xenix. Then: SCO Xenix, SCO Unix, AIX, SCO-OS5, Caldera, RedHat 7, Debian Sarge, RedHat ES4, Debian Etch, Redhat ES5, Debian Lenny, RedHat ES6, Debian Squeeze. I've migrated our clients through those various versions with minimal interruption while preserving their investments in hardware and staff knowledge over time.
