pwd prints the name of the current directory. Synopsis:
The program accepts the following options. Also see Common options.
If -L and -P are both given, the last one takes precedence. If neither option is given, then this implementation uses -P as the default unless the POSIXLY_CORRECT environment variable is set.
Due to shell aliases and built-in pwd functions, using an
unadorned pwd interactively or in a script may get you
different functionality than that described here. Invoke it via
env pwd ...) to avoid interference
from the shell.
An exit status of zero indicates success, and a nonzero value indicates failure.
