360 | =head1 DESCRIPTION | |
361 | ||
441496b2 CB |
362 | The File::Copy module provides two basic functions, C<copy> and |
363 | C<move>, which are useful for getting the contents of a file from | |
364 | one place to another. | |
365 | ||
366 | =over 4 | |
367 | ||
0cdecedb GS |
368 | =item copy |
369 | X<copy> X<cp> | |
441496b2 CB |
370 | |
371 | The C<copy> function takes two | |
f716a1dd | 372 | parameters: a file to copy from and a file to copy to. Either |
373 | argument may be a string, a FileHandle reference or a FileHandle | |
374 | glob. Obviously, if the first argument is a filehandle of some | |
375 | sort, it will be read from, and if it is a file I<name> it will | |
376 | be opened for reading. Likewise, the second argument will be | |
96a91e01 | 377 | written to (and created if need be). Trying to copy a file on top |
378 | of itself is a fatal error. | |
71be2cbc | 379 | |
380 | B<Note that passing in | |
9b957b78 | 381 | files as handles instead of names may lead to loss of information |
382 | on some operating systems; it is recommended that you use file | |
e6434134 | 383 | names whenever possible.> Files are opened in binary mode where |
8dcee03e | 384 | applicable. To get a consistent behaviour when copying from a |
e6434134 | 385 | filehandle to a file, use C<binmode> on the filehandle. |
f716a1dd | 386 | |
387 | An optional third parameter can be used to specify the buffer | |
388 | size used for copying. This is the number of bytes from the | |
3a964d77 | 389 | first file, that will be held in memory at any given time, before |
f716a1dd | 390 | being written to the second file. The default buffer size depends |
338de517 | 391 | upon the file, but will generally be the whole file (up to 2MB), or |
f716a1dd | 392 | 1k for filehandles that do not reference files (eg. sockets). |
393 | ||
394 | You may use the syntax C<use File::Copy "cp"> to get at the | |
395 | "cp" alias for this function. The syntax is I<exactly> the same. | |
396 | ||
0cdecedb GS |
397 | =item move |
398 | X<move> X<mv> X<rename> | |
441496b2 CB |
399 | |
400 | The C<move> function also takes two parameters: the current name | |
71be2cbc | 401 | and the intended name of the file to be moved. If the destination |
402 | already exists and is a directory, and the source is not a | |
403 | directory, then the source file will be renamed into the directory | |
404 | specified by the destination. | |
405 | ||
406 | If possible, move() will simply rename the file. Otherwise, it copies | |
407 | the file to the new location and deletes the original. If an error occurs | |
408 | during this copy-and-delete process, you may be left with a (possibly partial) | |
441496b2 CB |
409 | copy of the file under the destination name. |
410 | ||
411 | You may use the "mv" alias for this function in the same way that | |
412 | you may use the "cp" alias for C<copy>. | |

9b957b78 | 417 | File::Copy also provides the C<syscopy> routine, which copies the |
418 | file specified in the first parameter to the file specified in the | |
419 | second parameter, preserving OS-specific attributes and file | |
420 | structure. For Unix systems, this is equivalent to the simple | |
f1442e8b SB |
421 | C<copy> routine, which doesn't preserve OS-specific attributes. For |
422 | VMS systems, this calls the C<rmscopy> routine (see below). For OS/2 | |
423 | systems, this calls the C<syscopy> XSUB directly. For Win32 systems, | |
424 | this calls C<Win32::CopyFile>. | |

426 | On Mac OS (Classic), C<syscopy> calls C<Mac::MoreFiles::FSpFileCopy>, |
427 | if available. | |
428 | ||
338de517 | 429 | B<Special behaviour if C<syscopy> is defined (OS/2, VMS and Win32)>: |
9b957b78 | 430 | |
71be2cbc | 431 | If both arguments to C<copy> are not file handles, |
432 | then C<copy> will perform a "system copy" of | |
9b957b78 | 433 | the input file to a new output file, in order to preserve file |
434 | attributes, indexed file structure, I<etc.> The buffer size | |
71be2cbc | 435 | parameter is ignored. If either argument to C<copy> is a |
436 | handle to an opened file, then data is copied using Perl | |
9b957b78 | 437 | operators, and no effort is made to preserve file attributes |
438 | or record structure. | |
439 | ||
55497cff | 440 | The system copy routine may also be called directly under VMS and OS/2 |
441 | as C<File::Copy::syscopy> (or under VMS as C<File::Copy::rmscopy>, which | |
71be2cbc | 442 | is the routine that does the actual work for syscopy). |

444 | =item rmscopy($from,$to[,$date_flag]) | |
0cdecedb | 445 | X<rmscopy> |
9b957b78 | 446 | |
71be2cbc | 447 | The first and second arguments may be strings, typeglobs, typeglob |
448 | references, or objects inheriting from IO::Handle; | |
449 | they are used in all cases to obtain the | |
9b957b78 | 450 | I<filespec> of the input and output files, respectively. The |
451 | name and type of the input file are used as defaults for the | |
452 | output file, if necessary. | |
453 | ||
454 | A new version of the output file is always created, which | |
455 | inherits the structure and RMS attributes of the input file, | |
456 | except for owner and protections (and possibly timestamps; | |
457 | see below). All data from the input file is copied to the | |
458 | output file; if either of the first two parameters to C<rmscopy> | |
459 | is a file handle, its position is unchanged. (Note that this | |
460 | means a file handle pointing to the output file will be | |
461 | associated with an old version of that file after C<rmscopy> | |
462 | returns, not the newly created version.) | |
463 | ||
464 | The third parameter is an integer flag, which tells C<rmscopy> | |
1fef88e7 JM |
465 | how to handle timestamps. If it is E<lt> 0, none of the input file's |
466 | timestamps are propagated to the output file. If it is E<gt> 0, then | |
9b957b78 | 467 | it is interpreted as a bitmask: if bit 0 (the LSB) is set, then |
468 | timestamps other than the revision date are propagated; if bit 1 | |
469 | is set, the revision date is propagated. If the third parameter | |
470 | to C<rmscopy> is 0, then it behaves much like the DCL COPY command: | |
471 | if the name or type of the output file was explicitly specified, | |
472 | then no timestamps are propagated, but if they were taken implicitly | |
473 | from the input filespec, then all timestamps other than the | |
474 | revision date are propagated. If this parameter is not supplied, | |
475 | it defaults to 0. | |
476 | ||
477 | Like C<copy>, C<rmscopy> returns 1 on success. If an error occurs, | |
478 | it sets C<$!>, deletes the output file, and returns 0. | |

493 | On Mac OS (Classic), the path separator is ':', not '/', and the | |
494 | current directory is denoted as ':', not '.'. You should be careful | |
495 | about specifying relative pathnames. While a full path always begins | |
496 | with a volume name, a relative pathname should always begin with a | |
497 | ':'. If specifying a volume name only, a trailing ':' is required. | |
498 | ||
499 | E.g. | |
500 | ||
501 | copy("file1", "tmp"); # creates the file 'tmp' in the current directory | |
502 | copy("file1", ":tmp:"); # creates :tmp:file1 | |
503 | copy("file1", ":tmp"); # same as above | |
0cdecedb | 504 | copy("file1", "tmp"); # same as above, if 'tmp' is a directory (but don't do |
6c254d95 CN |
505 | # that, since it may cause confusion, see example #1) |
506 | copy("file1", "tmp:file1"); # error, since 'tmp:' is not a volume | |
507 | copy("file1", ":tmp:file1"); # ok, partial path | |
508 | copy("file1", "DataHD:"); # creates DataHD:file1 | |
