How Do I Navigate the File System?
You can move from one directory to another using the cd command. For example, if you are in your home directory (/home/hermie) and want to switch to the recipes directory (/home/hermie/recipes), the following command does the trick: cd recipes
To switch back to your home directory, you could type
but there are two shortcuts you will find useful. The first is the double-dot (..) notation, as in
This will move you one level up, to the parent directory. You can even enter something like
to move up to the parent and then go back down to a directory that is at the same level as the current one. This double-dot notation is not specific to the cd command, though. You can use it with any Linux command that needs a file name as input. You might also see the single-dot (.) notation, which means "this directory." It wouldn't make much sense to enter cd . because you'd still be in the same directory, but there are other commands (notably, the find command, described in the "Important Linux Commands" section). where it's convenient to use the single dot as shorthand for the current directory name.
Another directory navigation shortcut involves using $HOME. No matter what directory you are in, the following command will return you to your personal recipes directory:
And if you want to change to another user's home directory, you can use the tilde (~) notation. In the following examples, the tilde character is shorthand for "the home directory of." You must put the name of a user on your system immediately after the tilde.
For example, cd ~sigmund means "change to sigmund's home directory;"
cd ~edbo/stuff means "change to edbo's stuff directory."
The single-dot, double-dot, and tilde notations are useful in conjunction with the cd command, but they can also be used in any Linux command where you need to enter a file or directory name.
TIP: One common mistake people make in navigating Linux directories is using a slash in front of file names when it is not needed. Suppose you have a bin directory under your home directory. If you were at /home/hermie and you entered cd /bin, you'd end up at the bin underneath the root directory--oops. (Linux understands the slash before bin as telling it to go to the root directory first and then to the bin directory just below the root.) The correct way to reach the bin directory under /home/hermie is to type from within your home directory (/home/hermie) cd bin. Don't use a leading slash unless you're sure you want to start at the top (root) of the file tree.

this command is back us on that directory where we lastly typed 'pwd' command.
I am also sure that all of them do support
And this will take you to your home directory for sure.
i need to access a disk-on-key that contains
Microsoft word/Excell files.
When i insert a disk-on-key on the usb port my (year 2000) pentium 3 computer does not seem to notice.
What is the quick one time solution ?
What is the long term/permanent solution ?
