|
|
.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.
