解决方法 这里有一个通用的模式,就是这个：这是一个集交集问题,因此可以使用Perl“sets”轻松解决,我们倾向于称之为哈希:).

方法是创建一个数据文件的集合(即将其索引到哈希表中,如下所示：％set =(a => 1,b => 1,c => 1),实际值是无关紧要的,因为我们将使用“set membership operator”来测试它.

完成之后,通过其他数据集并在上面的％set中测试其中一个键(在您的情况下,源ID)的成员资格是一件简单的事情.

因此,假设频道映射文件采用以下格式：

ID,姓名

并且源ID文件每行只有一个ID,您可以执行以下 *** 作：

open my $CHANNEL_MAP,q{<},$channel_map_file_name or dIE $!;my %channel_map    = map {        chomp;        my @mapPing = split /,/;        $mapPing[0] => $mapPing[1] # not needed,just being explicit.      } <$CHANNEL_MAP>;close $CHANNEL_MAP or dIE $!;# source ID file passed as a command line argumentwhile (<>) {    chomp;    print "$_ = $channel_map{$_}\n"        if exists $channel_map{$_};}

但是,这似乎有点无意义,因为您似乎想要做的是按现有源ID过滤通道映射文件.在这种情况下,您可以简单地索引源ID文件(使用上面的技术),然后只需浏览通道映射文件并打印源ID中存在ID的每一行.
