learning the shell, some commands don't work
Binary package hint: firefox-3.0
in lesson 2 of learning the shell, an example of changing directory
cd /usr/x11r6/bin this should take you to the bin directory.
I get: no such file or directory, I am able to do "cd /usr" and I get to the usr directory, if I do from the usr directory "cd /x11r6" I get no such file or derectory.
also I can't do "cd / (any directories like music or videos or any of the directories) I always get: no such file or directory. If i check my disc information, I can find the usr directory, in it I can find the x11r6 directory and in that directory i fin the bin directory.
Wy does the command not able to find those directory, is my bash program missing some links?
System info: download of ubuntu 8.10 with all updates and upgrade (no change in the problem before or after the updates or upgrade, even removed and reinstalled bash.
Pentium 3 at 200 mghz.

Hi,
On Linux file names are case sensitive: "X11R6" is different from "x11r6".
If you want to go to /usr/X11R6 with two commands, you have to enter "cd /usr" first, then "cd X11R6" (with no slash because this directory is a sub-directory of /usr).
I hope this answers your question.
