SYNOPSIS
| pwd | [ -LP] | 
DESCRIPTION
The pwd utility prints the absolute
    pathname of the current working directory to the standard output.
The options are as follows:
- -L
- If the PWDenvironment variable is an absolute pathname that references the current directory and doesn't contain path components of "." or "..", thenPWDis printed as the name of the current directory. Otherwise, act as if the-Poption was given.
- -P
- Print the physical path to the current working directory, with symbolic links in the path resolved.
The -L and -P
    options override each other and the command's actions are determined by the
    last one specified. The default if no options are given is
    -P.
For an explanation of the directory hierarchy, see hier(7).
ENVIRONMENT
- PWD
- The presumptive logical path to the current working directory.
EXIT STATUS
The pwd utility exits 0 on success,
    and >0 if an error occurs.

STANDARDS
The pwd utility is compliant with the
    IEEE Std 1003.1-2008 (“POSIX.1”)
    specification, except the standard says the default if no options are given
    should be to behave as if -L had been specified.
HISTORY
An pwd utility appeared in
    Version 5 AT&T UNIX. Support for the
    -L option was added in OpenBSD
    5.6.
CAVEATS
pwd also exists as a built-in to
    ksh(1), which
    may have a different default behavior.
