如何讀取文件並用名稱替換該值

我有一個關於我將調用源ID的文件。我想讀取該文件並根據源ID爲其添加一個名稱，例如15431 = MyTV8。我有一個列出源ID和名稱的文件，但我不知道如何讀取原始ID並將頻道映射文件中的名稱添加到具有源ID的文件中。如何讀取文件並用名稱替換該值

源ID的小樣本我輪詢

這將是很好，如果你添加你的示例文件 – 2010-08-21 10:40:34

我只是做了一點關於佩德羅的代碼重新因素，它的工作非常感謝您的幫助！ – evilbits 2010-08-22 16:07:16

有一種普遍的模式在這裏，正是這樣：這是一組交集問題，因此可以用Perl「sets」輕鬆解決，我們稱之爲哈希:)。

該方法是創建一個數據文件的集合（即將其索引到散列表中，如下所示：%set = (a => 1, b => 1, c => 1)，其中實際值不重要，因爲我們要用「集合成員運營商」exists）。

一旦你有了它，通過其他數據集並測試上面的%set中其中一個鍵（在你的情況下，源ID）的成員資格是一件簡單的事情。

因此，假設該信道映射文件的格式如下：

ID,NAME

和源ID文件每行只有一個ID中，你可以做到以下幾點：

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 argument 
while (<>) { 
    chomp; 
    print "$_ = $channel_map{$_}\n" 
     if exists $channel_map{$_}; 
}

但是，這似乎有點沒有意義，因爲您似乎只想通過現有源ID過濾頻道映射文件。在這種情況下，您可以簡單地爲源ID文件編制索引（使用上述技術），然後簡單地瀏覽通道映射文件並打印源ID中存在ID的每一行。

非常感謝您的幫助！這絕對讓我走上了正軌，也將幫助我更多地理解perl。 – evilbits 2010-08-22 02:58:39

這一切都很模糊，因爲你不清楚你的文件的格式。

但是，假設您有一個名爲names.txt的文件，其中列出了「15431 = MyTV8」格式的名稱，每行一個，而您有另一個文件，同時只列出數字，您可以使用如下所示的內容：

#!/usr/bin/perl 

open NAMES, '< names.txt' or die [email protected]; 
my %names = map { /(\d+) = (.+)/; ($1, $2) } (<NAMES>); 

while (<>) 
{ 
    chomp; 
    if (exists $names{$_}) { 
     print "$_ = $names{$_}\n"; 
    } else { 
     print "$_\n"; 
    } 
}
