16 | =head1 DESCRIPTION |
902bacac |
17 | |
04929354 |
18 | This module provides functions for determining the pathname of the |
19 | current working directory. It is recommended that getcwd (or another |
20 | *cwd() function) be used in I<all> code to ensure portability. |
f06db76b |
21 | |
04929354 |
22 | By default, it exports the functions cwd(), getcwd(), fastcwd(), and |
23 | fastgetcwd() into the caller's namespace. |

27 | |
04929354 |
28 | Each of these functions are called without arguments and return the |
29 | absolute path of the current working directory. |

33 | =item getcwd |
34 | |
35 | my $cwd = getcwd(); |
36 | |
37 | Returns the current working directory. |
38 | |
39 | Re-implements the getcwd(3) (or getwd(3)) functions in Perl. |
40 | |
41 | =item cwd |
42 | |
43 | my $cwd = cwd(); |
44 | |
45 | The cwd() is the most natural form for the current architecture. For |
46 | most systems it is identical to `pwd` (but without the trailing line |
47 | terminator). |
48 | |
49 | Unfortunately, cwd() tends to break if called under taint mode. |
50 | |
51 | =item fastcwd |
52 | |
53 | my $cwd = fastcwd(); |
54 | |
55 | A more dangerous version of getcwd(), but potentially faster. |
56 | |
57 | It might conceivably chdir() you out of a directory that it can't |
58 | chdir() you back into. If fastcwd encounters a problem it will return |
59 | undef but will probably leave you in a different directory. For a |
60 | measure of extra security, if everything appears to have worked, the |
61 | fastcwd() function will check that it leaves you in the same directory |
62 | that it started in. If it has changed it will C<die> with the message |
63 | "Unstable directory path, current directory changed |
64 | unexpectedly". That should never happen. |
65 | |
66 | =item fastgetcwd |
67 | |
68 | my $cwd = fastgetcwd(); |
f06db76b |
69 | |
902bacac |
70 | The fastgetcwd() function is provided as a synonym for cwd(). |

75 | =head2 abs_path and friends |
76 | |
77 | These functions are exported only on request. They each take a single |
78 | argument and return the absolute pathname for it. |
79 | |
80 | =over 4 |
81 | |
82 | =item abs_path |
83 | |
84 | my $abs_path = abs_path($file); |
85 | |
86 | Uses the same algorithm as getcwd(). Symbolic links and relative-path |
87 | components ("." and "..") are resolved to return the canonical |
88 | pathname, just like realpath(3). |
89 | |
90 | =item realpath |
91 | |
92 | my $abs_path = realpath($file); |
93 | |
94 | A synonym for abs_path(). |
95 | |
96 | =item fast_abs_path |
97 | |
510179aa |
98 | my $abs_path = fast_abs_path($file); |
04929354 |
99 | |
100 | A more dangerous, but potentially faster version of abs_path. |

106 | If you ask to override your chdir() built-in function, |
107 | |
108 | use Cwd qw(chdir); |
109 | |
110 | then your PWD environment variable will be kept up to date. Note that |
111 | it will only be kept up to date if all packages which use chdir import |
112 | it from Cwd. |

120 | |
04929354 |
121 | Since the path seperators are different on some operating systems ('/' |
122 | on Unix, ':' on MacPerl, etc...) we recommend you use the File::Spec |
123 | modules wherever portability is a concern. |

126 | |
127 | Actually, on Mac OS, the C<getcwd()>, C<fastgetcwd()> and C<fastcwd()> |
128 | functions are all aliases for the C<cwd()> function, which, on Mac OS, |
129 | calls `pwd`. Likewise, the C<abs_path()> function is an alias for |
130 | C<fast_abs_path()>. |
