36.Os
37.Sh NAME
38.Nm pwd
39.Nd return working directory name
40.Sh SYNOPSIS
41.Nm
42.Op Fl L | P
43.Sh DESCRIPTION
44The
45.Nm
46utility writes the absolute pathname of the current working directory to
47the standard output.
48.Pp
49Some shells may provide a builtin
50.Nm
51command which is similar or identical to this utility.
52Consult the
53.Xr builtin 1
54manual page.
55.Pp
56The options are as follows:
57.Bl -tag -width indent
58.It Fl L
59Display the logical current working directory.
60.It Fl P
61Display the physical current working directory (all symbolic links resolved).
62.El
63.Pp
64If no options are specified, the
65.Fl P
66option is assumed.
67.Sh ENVIRONMENT
68Environment variables used by
69.Nm :
70.Bl -tag -width ".Ev PWD"
71.It Ev PWD
72Logical current working directory.
73.El
74.Sh EXIT STATUS
75.Ex -std
76.Sh EXAMPLES
77Show current working directory with symbolic links resolved:
78.Bd -literal -offset indent
79$ /bin/pwd
80/usr/src/sys/kern
81.Ed
82.Pp
83Show the logical current directory.
84Then use
85.Xr file 1
86to inspect the
87.Pa /sys
88directory:
89.Bd -literal -offset indent
90$ /bin/pwd -L
91/sys/kern
92$ file /sys
93/sys: symbolic link to usr/src/sys
94.Ed

100.Xr sh 1 ,
101.Xr getcwd 3
102.Sh STANDARDS
103The
104.Nm
105utility conforms to
106.St -p1003.1-2001 .
107.Sh HISTORY
108The
109.Nm
110command appeared in
111.At v5 .
112.Sh BUGS
113In
114.Xr csh 1
115the command
116.Ic dirs
117is always faster because it is built into that shell.
118However, it can give a different answer in the rare case
119that the current directory or a containing directory was moved after
120the shell descended into it.
121.Pp
122The
123.Fl L
124option does not work unless the
125.Ev PWD
126environment variable is exported by the shell.
