There are two main flags in pwd command .

pwd -L: Prints the symbolic path.

pwd -P: Prints the actual path.

For more details regarding symbolic links , refer to symbolic link page.

pwd -L

--L is the shorthand for the logic option . The -L option instructs pwd to print the working directory path, including any symbolic links. We used a symbolic link to navigate to a directory and ran pwd -L.

Syntax : pwd -L

pwd -P

Here, the --P is the shorthand for the path. Prints the path to the current directory. All the components are directory names, and symbolic links are resolved.

Syntax : pwd -P

Figure.2 shows pwd -L command to check the logical path of the link and pwd -P command to check the physical path of the link.
