What are relative paths?

Relative paths are file or directory paths that are specified in relation to the current working directory. Instead of starting from the root directory (/), relative paths begin from the current location in the filesystem. This makes them shorter and often easier to use when navigating within a specific directory structure.

Key Points about Relative Paths:

Current Directory Reference: A relative path does not start with a /. It is based on your current directory. For example, if you are in /home/user, a relative path to a file named file.txt in the same directory would simply be:
```
file.txt
```
Using .. to Move Up: You can use .. to refer to the parent directory. For example, if you are in /home/user/testdir and want to access a file in /home/user, you can use:
```
../file.txt
```
Combining Paths: You can combine relative paths to navigate through directories. For example, if you want to access a file in a subdirectory called subdir within your current directory, you would use:
```
subdir/file.txt
```

Example

Assuming your current directory is /home/user:

To access a file in the same directory:
```
ls file.txt
```
To access a file in a subdirectory called documents:
```
ls documents/file.txt
```
To access a file in the parent directory:
```
ls ../file.txt
```

Summary

Relative paths are convenient for navigating the filesystem without needing to specify the full path, making them useful for scripts and commands when working within a known directory structure.
