Question

我有一个.txt文件，其中包含我的电视频道播放列表的时间表。在文件中有许多字符为＆＃39; logo_0 2 ＆＃39; in。我运行ruby命令来处理播放列表（.txt文件）。我想如何删除所有＆＃39; logo_0 2 ＆＃39;在红宝石？随附的是.txt文件和执行该过程的rb文件。我需要消除＆＃39; logo_0 2 ＆＃39;在.txt文件中。

Answer 1

如果你分享你的ruby代码会很好，我们可以告诉你如何更新它。

filename = 'item.txt'
contents=File.read(filename)
contents.gsub!("logo_0 2\n", '')
File.open(filename, "w") { |f| f << contents }

如果您只想替换字符contents.gsub!("logo_0 2", '')，请使用此语句代替contents.gsub!("logo_0 2\n", '')
