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

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