3=head1 NAME
4
5Cwd - get pathname of current working directory
6
7=head1 SYNOPSIS
8
9 use Cwd;
10 my $dir = getcwd;
11
12 use Cwd 'abs_path';
13 my $abs_path = abs_path($file);
14
15=head1 DESCRIPTION
16
17This module provides functions for determining the pathname of the
18current working directory. It is recommended that getcwd (or another
19*cwd() function) be used in I<all> code to ensure portability.
20
21By default, it exports the functions cwd(), getcwd(), fastcwd(), and
22fastgetcwd() (and, on Win32, getdcwd()) into the caller's namespace.
23
24
25=head2 getcwd and friends
26
27Each of these functions are called without arguments and return the
28absolute path of the current working directory.
29
30=over 4
31
32=item getcwd
33
34 my $cwd = getcwd();
35
36Returns the current working directory.
37
38Exposes the POSIX function getcwd(3) or re-implements it if it's not
39available.
40
41=item cwd
42
43 my $cwd = cwd();
44
45The cwd() is the most natural form for the current architecture. For
46most systems it is identical to `pwd` (but without the trailing line
47terminator).
48
49=item fastcwd
50
51 my $cwd = fastcwd();
52
53A more dangerous version of getcwd(), but potentially faster.
54
55It might conceivably chdir() you out of a directory that it can't
56chdir() you back into. If fastcwd encounters a problem it will return
57undef but will probably leave you in a different directory. For a
58measure of extra security, if everything appears to have worked, the
59fastcwd() function will check that it leaves you in the same directory
60that it started in. If it has changed it will C<die> with the message
61"Unstable directory path, current directory changed
62unexpectedly". That should never happen.
63
64=item fastgetcwd
65
66 my $cwd = fastgetcwd();
67
68The fastgetcwd() function is provided as a synonym for cwd().
69
70=item getdcwd
71
72 my $cwd = getdcwd();
73 my $cwd = getdcwd('C:');
74
75The getdcwd() function is also provided on Win32 to get the current working
76directory on the specified drive, since Windows maintains a separate current
77working directory for each drive. If no drive is specified then the current
78drive is assumed.
79
80This function simply calls the Microsoft C library _getdcwd() function.
81
82=back
83
84
85=head2 abs_path and friends
86
87These functions are exported only on request. They each take a single
88argument and return the absolute pathname for it. If no argument is
89given they'll use the current working directory.
90
91=over 4
92
93=item abs_path
94
95 my $abs_path = abs_path($file);
96
97Uses the same algorithm as getcwd(). Symbolic links and relative-path
98components ("." and "..") are resolved to return the canonical
99pathname, just like realpath(3).
100
101=item realpath
102
103 my $abs_path = realpath($file);
104
105A synonym for abs_path().
106
107=item fast_abs_path
108
109 my $abs_path = fast_abs_path($file);
110
111A more dangerous, but potentially faster version of abs_path.
112
113=back
114
115=head2 $ENV{PWD}
116
117If you ask to override your chdir() built-in function,
118
119 use Cwd qw(chdir);
120
121then your PWD environment variable will be kept up to date. Note that
122it will only be kept up to date if all packages which use chdir import
123it from Cwd.
124
125
126=head1 NOTES
127
128=over 4
129
130=item *
131
132Since the path seperators are different on some operating systems ('/'
133on Unix, ':' on MacPerl, etc...) we recommend you use the File::Spec
134modules wherever portability is a concern.
135
136=item *
137
138Actually, on Mac OS, the C<getcwd()>, C<fastgetcwd()> and C<fastcwd()>
139functions are all aliases for the C<cwd()> function, which, on Mac OS,
140calls `pwd`. Likewise, the C<abs_path()> function is an alias for
141C<fast_abs_path()>.
