如何在Perl中tar多个文件？

Question

How can I tar multiple directories and also append files with some pattern like '.txt' and exclude some directories and exclude some patterns like '.exe' all into a single tar file. The main point is the number of directories are unknown(dynamic), so I need to loop through I guess?

Answer 1

我使用Archive :: Tar并使用Class :: Path填充@filelist （特别是Class::Path::Dir的recurse方法）

Answer 2

Assuming you have worked out what files you want using File::Find then something like

    my @dir = qw/a b/ ;
    system "tar -cvf mytar @dir" ;

might work. But you might find that the command line is too long.

In which case maybe write the list of files to a file and use the option

   --files-from=NAME

(and please don't tell me you are not allowed to write to files)

Answer 3

If for some reason you cannot, or are not permitted to, install additional modules beyond the base system you could use File::Find instead of Class::Path.

It sounds like you already know how to call out to the system tar command so I'll leave it at that.
