What is the difference between -L and -P?

The -L and -P options for the pwd command in Linux specify how the current working directory is displayed, particularly in relation to symbolic links:

-L (Logical Path):
- Displays the logical path of the current directory.
- If you are in a directory that is a symbolic link, pwd -L will show the path as it appears in the file system, including the symbolic link.
- This is the default behavior of pwd if no options are specified.
Example:
If you are in a directory /home/user/docs where docs is a symbolic link to /mnt/storage/docs, running:
```
pwd -L
```
will output:
```
/home/user/docs
```
-P (Physical Path):
- Displays the physical path of the current directory.
- It resolves all symbolic links and shows the actual path in the file system.
- This option is useful when you want to see the real directory structure without any symbolic links.
Example:
Using the same scenario as above, running:
```
pwd -P
```
will output:
```
/mnt/storage/docs
```

In summary, use -L to see the path as it is logically represented (including symbolic links) and -P to see the actual physical path without symbolic links.
