The -P option in the pwd command stands for "physical." When you use pwd -P, it prints the current working directory as a physical path, resolving any symbolic links to show the actual directory on the filesystem.
For example:
cd /some/symlink
pwd -PIf /some/symlink points to /actual/directory, the output will be /actual/directory, showing the real path rather than the symbolic link.
In summary:
pwd -L: Shows the logical path, including symbolic links.pwd -P: Shows the physical path, resolving any symbolic links.
