How can I copy a directory but ignore some files in Perl?

Question

In my Perl code, I need to copy a directory from one location to another on the same host excluding some files/patterns (eg *.log, ./myDir/abc.cl). What would be the optimum way of doing this in Perl across all the platforms? On Windows, xcopy is one such solution. On unix platforms, is there a way to do this in Perl?

Answer 1

I think you're looking for rsync . It's not Perl, but it's going to work a lot better than anything you make in Perl:

% rsync --exclude='*.log' --exclude='./myDir/abc.cl' SOURCE DEST

If you have a bunch of patterns, you can put those all in a file:

*.log
./myDir/abc.cl

Now ignore all the patterns in a file:

% rsync --exclude-from=do_not_sync.txt SOURCE DEST

Answer 2

我会使用File::Find ，并一步在每个文件，但不是调用File::Copy的copy()上的每个文件，最先看到的测试，如果它的模式匹配，然后next ，如果它。

On *nix, you can use native tar command, with -exclude options . Then after creating the tar file, you can bring it over to your destination to untar it.
