在 Tmux + ZSH falis 中使用 Silver Searcher 的正则表达式

Question

我正在尝试使用正则表达式通过管道 ag 结果，但它不起作用。

~/c/octoly git:1470 ❯❯❯ drake routes | ag pro_store --page=less -r

我正在尝试获取以 pro_store 开头的结果。我读过破损的管道可能是因为 ag 的东西在 drake 的东西之前结束，但我不明白这是怎么回事以及为什么会发生这种情况。

Answer 1

试试 drake routes | ag "^ *pro_store" --page=less -r

您的输出不是 "start" 和 pro_store，而是多个空格和 then pro_store。这就是 [:space:]* 添加到您的正则表达式的原因。
