我正在尝试这样做：

rake routes | less

但它会产生以下奇怪的字符，并且less会破坏以使其无法正确搜索或响应。这是新的，并且已经使用了几年。我的系统上的某些东西发生了变化，我不知道如何停止或更改它！我怎样才能避免这个问题？

这些看起来像 ANSI 颜色转义序列。好像 less 没有正确解释序列。你确定你没有使用更少的选项吗？也许有一些选项，例如less -Ror less --RAW-CONTROL-CHARS。我承认我对 ANSI 颜色转义序列知之甚少。

Jared 说您需要使用less -R来解释颜色序列是正确的。

就失去对less导航的控制而言，我认为这不是由 引起的rake，而是由试图从 STDIN 读取的 rails 中的某些东西引起的。

要解决此问题，请重定向 STDIN：

rake routes </dev/null | less
