+.Sh NAME
+.Nm pwd
+.Nd return working directory name
+.Sh SYNOPSIS
+.Nm
+.Op Fl LP
+.Sh DESCRIPTION
+.Nm
+writes the absolute pathname of the current working directory to
+the standard output.
+.Pp
+The following options are available:
+.Bl -tag -width indent
+.It Fl L
+If the
+.Ev PWD
+environment variable is an absolute pathname that contains
+neither "/./" nor "/../" and references the current directory, then
+.Ev PWD
+is assumed to be the name of the current directory.
+.It Fl P
+Print the physical path to the current working directory, with symbolic
+links in the path resolved.
+.El
+.Pp
+The default for the
+.Nm
+command is
+.Fl P .
+.Pp
+.Nm
+is usually provided as a shell builtin (which may have a different
+default).
+.Sh EXIT STATUS
+The
+.Nm
+utility exits 0 on success, and \*[Gt]0 if an error occurs.
+.Sh SEE ALSO
+.Xr cd 1 ,
+.Xr csh 1 ,
+.Xr ksh 1 ,
+.Xr sh 1 ,
+.Xr getcwd 3
+.Sh STANDARDS
+The
+.Nm
+utility is expected to be conforming to
+.St -p1003.1 ,
+except that the default is
+.Fl P
+not
+.Fl L .
+.Sh BUGS
+In
+.Xr csh 1
+the command
+.Ic dirs
+is always faster (although it can give a different answer in the rare case
+that the current directory or a containing directory was moved after
+the shell descended into it).
+.Pp
+.Nm
+.Fl L
+relies on the file system having unique inode numbers.
+If this is not true (e.g., on FAT file systems) then
+.Nm
+.Fl L
+may fail to detect that
+.Ev PWD
+is incorrect.
