36.Dt PWD 1
37.Os
38.Sh NAME
39.Nm pwd
40.Nd return working directory name
41.Sh SYNOPSIS
42.Nm
43.Op Fl LP
44.Sh DESCRIPTION
45.Nm
46writes the absolute pathname of the current working directory to
47the standard output.
48.Pp
49The following options are available:
50.Bl -tag -width indent
51.It Fl L
52If the
53.Ev PWD
54environment variable is an absolute pathname that contains
55neither "/./" nor "/../" and references the current directory, then
56.Ev PWD
57is assumed to be the name of the current directory.
58.It Fl P
59Print the physical path to the current working directory, with symbolic
60links in the path resolved.
61.El
62.Pp
63The default for the
64.Nm
65command is
66.Fl P .
67.Pp
68.Nm
69is usually provided as a shell builtin (which may have a different
70default).
71.Sh EXIT STATUS
72The
73.Nm
74utility exits 0 on success, and \*[Gt]0 if an error occurs.
75.Sh SEE ALSO
76.Xr cd 1 ,
77.Xr csh 1 ,
78.Xr ksh 1 ,
79.Xr sh 1 ,
80.Xr getcwd 3
81.Sh STANDARDS
82The
83.Nm
84utility is expected to be conforming to
85.St -p1003.1 ,
86except that the default is
87.Fl P
88not
89.Fl L .
90.Sh BUGS
91In
92.Xr csh 1
93the command
94.Ic dirs
95is always faster (although it can give a different answer in the rare case
96that the current directory or a containing directory was moved after
97the shell descended into it).
98.Pp
99.Nm
100.Fl L
101relies on the file system having unique inode numbers.
102If this is not true (e.g., on FAT file systems) then
103.Nm
104.Fl L
105may fail to detect that
106.Ev PWD
107is incorrect.
