04929354 | 16 | =head1 DESCRIPTION |
902bacac | 17 | |
04929354 MS |
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 MS |
22 | By default, it exports the functions cwd(), getcwd(), fastcwd(), and |
23 | fastgetcwd() into the caller's namespace. | |

04929354 MS |
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. | |

43 | =item cwd |
44 | ||
45 | my $cwd = cwd(); | |
46 | ||
47 | The cwd() is the most natural form for the current architecture. For | |
48 | most systems it is identical to `pwd` (but without the trailing line | |
49 | terminator). | |
50 | ||
bde417e1 | 51 | Unfortunately, cwd() is B<not> taint-safe. |
04929354 MS |
52 | |
53 | =item fastcwd | |
54 | ||
55 | my $cwd = fastcwd(); | |
56 | ||
57 | A more dangerous version of getcwd(), but potentially faster. | |
58 | ||
59 | It might conceivably chdir() you out of a directory that it can't | |
60 | chdir() you back into. If fastcwd encounters a problem it will return | |
61 | undef but will probably leave you in a different directory. For a | |
62 | measure of extra security, if everything appears to have worked, the | |
63 | fastcwd() function will check that it leaves you in the same directory | |
64 | that it started in. If it has changed it will C<die> with the message | |
65 | "Unstable directory path, current directory changed | |
66 | unexpectedly". That should never happen. | |
67 | ||
68 | =item fastgetcwd | |
69 | ||
70 | my $cwd = fastgetcwd(); | |
f06db76b | 71 | |
902bacac | 72 | The fastgetcwd() function is provided as a synonym for cwd(). |

77 | =head2 abs_path and friends |
78 | ||
79 | These functions are exported only on request. They each take a single | |
80 | argument and return the absolute pathname for it. | |

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

114 | If you ask to override your chdir() built-in function, | |
115 | ||
116 | use Cwd qw(chdir); | |
117 | ||
118 | then your PWD environment variable will be kept up to date. Note that | |
119 | it will only be kept up to date if all packages which use chdir import | |
120 | it from Cwd. | |

127 | =item * | |
128 | ||
04929354 MS |
129 | Since the path seperators are different on some operating systems ('/' |
130 | on Unix, ':' on MacPerl, etc...) we recommend you use the File::Spec | |
131 | modules wherever portability is a concern. | |

4d6b4052 JH |
134 | |
135 | Actually, on Mac OS, the C<getcwd()>, C<fastgetcwd()> and C<fastcwd()> | |
136 | functions are all aliases for the C<cwd()> function, which, on Mac OS, | |
137 | calls `pwd`. Likewise, the C<abs_path()> function is an alias for | |
138 | C<fast_abs_path()>. | |
