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

26 | |
04929354 |
27 | Each of these functions are called without arguments and return the |
28 | absolute path of the current working directory. |

32 | =item getcwd |
33 | |
34 | my $cwd = getcwd(); |
35 | |
36 | Returns the current working directory. |
37 | |
38 | Re-implements the getcwd(3) (or getwd(3)) functions in Perl. |
39 | |
40 | =item cwd |
41 | |
42 | my $cwd = cwd(); |
43 | |
44 | The cwd() is the most natural form for the current architecture. For |
45 | most systems it is identical to `pwd` (but without the trailing line |
46 | terminator). |
47 | |
04929354 |
48 | =item fastcwd |
49 | |
50 | my $cwd = fastcwd(); |
51 | |
52 | A more dangerous version of getcwd(), but potentially faster. |
53 | |
54 | It might conceivably chdir() you out of a directory that it can't |
55 | chdir() you back into. If fastcwd encounters a problem it will return |
56 | undef but will probably leave you in a different directory. For a |
57 | measure of extra security, if everything appears to have worked, the |
58 | fastcwd() function will check that it leaves you in the same directory |
59 | that it started in. If it has changed it will C<die> with the message |
60 | "Unstable directory path, current directory changed |
61 | unexpectedly". That should never happen. |
62 | |
63 | =item fastgetcwd |
64 | |
65 | my $cwd = fastgetcwd(); |
f06db76b |
66 | |
902bacac |
67 | The fastgetcwd() function is provided as a synonym for cwd(). |

72 | =head2 abs_path and friends |
73 | |
74 | These functions are exported only on request. They each take a single |
3ee63918 |
75 | argument and return the absolute pathname for it. If no argument is |
76 | given they'll use the current working directory. |

80 | =item abs_path |
81 | |
82 | my $abs_path = abs_path($file); |
83 | |
84 | Uses the same algorithm as getcwd(). Symbolic links and relative-path |
85 | components ("." and "..") are resolved to return the canonical |
86 | pathname, just like realpath(3). |
87 | |
88 | =item realpath |
89 | |
90 | my $abs_path = realpath($file); |
91 | |
92 | A synonym for abs_path(). |

95 | |
510179aa |
96 | my $abs_path = fast_abs_path($file); |
04929354 |
97 | |
98 | A more dangerous, but potentially faster version of abs_path. |

104 | If you ask to override your chdir() built-in function, |
105 | |
106 | use Cwd qw(chdir); |
107 | |
108 | then your PWD environment variable will be kept up to date. Note that |
109 | it will only be kept up to date if all packages which use chdir import |
110 | it from Cwd. |

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

124 | |
125 | Actually, on Mac OS, the C<getcwd()>, C<fastgetcwd()> and C<fastcwd()> |
126 | functions are all aliases for the C<cwd()> function, which, on Mac OS, |
127 | calls `pwd`. Likewise, the C<abs_path()> function is an alias for |
128 | C<fast_abs_path()>. |
