What are absolute paths?

Absolute paths are complete directory or file paths that specify the exact location of a file or directory in the file system, starting from the root directory. They provide a way to navigate to a specific location regardless of your current working directory.

Key Characteristics of Absolute Paths:

Starts from Root: An absolute path always begins with the root directory, represented by a single forward slash (/). This indicates the top level of the file system hierarchy.
Full Path Specification: It includes all directories leading to the target file or directory. For example, /home/labex/project/file.txt is an absolute path that specifies the exact location of file.txt.
Consistent Access: Since absolute paths provide the full address, they can be used from any location in the file system. This is similar to using a complete postal address to find a specific location.

Example of Absolute Paths:

To navigate to a specific directory:
```
cd /var/log
```
To access a file directly:
```
cat /home/labex/project/file.txt
```

Comparison with Relative Paths:

Relative Paths: These are paths that are relative to your current working directory. For example, if you are in /home/labex, you can access project/file.txt without specifying the full path.
Absolute Paths: Always specify the full path, making them more reliable for accessing files and directories from any location.

Why Use Absolute Paths?

Clarity: They eliminate ambiguity about the file's location.
Scripting: In scripts, using absolute paths ensures that the correct files are accessed regardless of the script's execution context.
