Unix/Linux Level Description and features:
OOPS.... was meant to include Linus: wizard - writes device drivers with "cat >" - is on first-name basis with Dennis, Bill, and Ken (and Linus:-)
Well... hell he was a director of the company, so therefore he was entitled get to log in a root on "the company" unix box.... it only seems logical that he should log in a root all the time.
But that was just the start...
Next thing were the permissions on the files/directories that he created. They were just wrong. We couldn't read some files he created that needed to be shared, we couldn't fix the permissions, we couldn't rename or move directories created by him. We couldn't even tell which were his creations.
I chatted to him about "root login issues", but at the end of the day, he was a director.
Finally one day he found the system was short of diskspace and notices that the files in/usr/bin were also in/bin (on AIX).... so he elects himself to clean up one directory.... rm -rf/usr/bin.
And so... one CAN learn from experience.
Unix/Linux Level Description and features: beginner - has not figured out how to get a directory listing novice - knows that "ls" will produce a directory listing
- has had his FIRST BAD EXPERIENCE with rm!!! user - is wondering how to move a directory
- knows how to read his mail and is wondering
how to read the news knowlegable - has figured out that mv(1) will move directories
- once used sed to do some text substitution expert - write C programs using vi and compiles with cc
- has figured out what "&&" and "||" are for hacker - uses adb because he doesn`t trust source
debuggers
- knows how to install bug fixes guru - uses adb on the kernel while system is loaded
- reads device driver source with his breakfast
- has learned how to breach security but no longer
needs to try wizard - writes device drivers with "cat >"
- is on first-name basis with Dennis, Bill, and Ken (and Linux -)
