To navigate to your home directory in Unix, you can use the command cd ~
or simply cd
without any arguments. The tilde symbol (~
) represents your home directory. Alternatively, you can use the command cd /home/username
, replacing "username" with your actual username, to achieve the same result.
In Unix, the parent directory is the directory that contains the current directory. It is represented by the symbol .. (two dots). When navigating the file system, you can use this symbol to move up one level in the directory hierarchy. For example, if you are in /home/user/documents, the parent directory would be /home/user.
Root directory.
When a user logs in to a Unix system, the current working directory normally starts at the directory/file
It's where all settings, documents, private files, etc. are located.
ls -lR directory
CD /
Once your in the directory you have to type the following: du -a
Typically, programs store program information in hidden files in your home directory. The 'ssh' program stores cached host keys in the ".ssh" folder.
Directory tree structure in Unix always starts at the top node, or "root" node. It contains all of the major level subdirectories underneath it. The root directory is called "/" (root).
root directory is the top of the directory tree. it is \ on windows (or c:\ d:\ etc.) and / on unix/linux
Unix accesses a file from a directory using a hierarchical file system structure. When a command is executed to access a file, the Unix kernel navigates through the directory tree, starting from the root directory, to locate the specified path. Each directory contains entries that map file names to their corresponding inode numbers, which store metadata and point to the actual data blocks on disk. By reading the inode, Unix can access the file's content efficiently.
The two links are for the current directory (.) and the parent directory (..). This is allow for easy directory traversal.
