Description of problem: Several problems: 1. man pwd does not show the -P or -L options 2. man pwd claims that "man info" will show more useful information. It doesn't. 3. pwd -h, pwd --help options are missing.
There is a bash builtin named pwd, and it is that version that has -P and -L options: the coreutils-provided pwd does not. To get information about the builtin, type 'help pwd'.
