Code:
[Kristian@localhost ~]$ pwd
/home/Kristian
So far so good. Remember, you're in /home/Kristian.
Code:
[Kristian@localhost ~]$ cd /usr/X11R6/bin
bash: cd: /usr/X11R6/bin: No such file or directory
You may not have that directory. Most Linux distributions these days use X.org rather than Xfree86, which is probably what was in use at the time the tutorial was written. Also, remember that Linux is case sensitive, so a directory called
x11r6 is different than one called
X11R6. If you know the starting letter of the directory you want you can let Linux auto-complete the name by pressing TAB twice.
Code:
[Kristian@localhost ~]$ pwd
/home/Kristian
[Kristian@localhost ~]$ ls
Desktop Documents Download Music Pictures Public Templates Videos
[Kristian@localhost ~]$ cd /usr/Download
bash: cd: /usr/Download: No such file or directory
[Kristian@localhost ~]$ pwd
/home/Kristian
Why are you putting /usr/ in front of the Download directory? When you do this, you're asking Linux to put you in the /usr/Download directory, not /home/Kristian/Download, which is what you want. All you need to do is say
cd Download from inside your current directory.
