|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
utility prints the absolute pathname of the current working directory to
|
|
the standard output.
|
|
.Pp
|
|
The options are as follows:
|
|
.Bl -tag -width Ds
|
|
.It Fl L
|
|
If the
|
|
.Ev PWD
|
|
environment variable is an absolute pathname that references the
|
|
current directory and doesn't contain path components of "." or "..",
|
|
then
|
|
.Ev PWD
|
|
is printed as the name of the current directory.
|
|
Otherwise, act as if the
|
|
.Fl P
|
|
option was given.
|
|
.It Fl P
|
|
Print the physical path to the current working directory, with symbolic
|
|
links in the path resolved.
|
|
.El
|
|
.Pp
|
|
The
|
|
.Fl L
|
|
and
|
|
.Fl P
|
|
options override each other and the command's actions are determined
|
|
by the last one specified.
|
|
The default if no options are given is
|
|
.Fl P .
