如何在bash中模拟zsh的全局别名？

Question

在syntax中，您可以定义全局别名。例如，

zsh

然后像这样使用它们：

alias -g G='| grep'
alias -g W='| wc -l'

可以在some_command G some_text W 中以某种方式模拟全局别名吗？

Answer 1

Assuming you never want to use capital G for any other purpose, you could add this to your .bashrc file:

bind '"G": "| grep"'

This will expand G to | grep as soon as you type it. That is, Shift+g no longer produces a capital G, but the string | grep. You'd want to choose a longer sequence that you would never expect to otherwise type, either by itself or as part of another word.

Answer 2

您可以将其保存到变量

中

g='| grep'

然后，你的命令可能是

eval some_command $G some_text

OR

some_command $G some_text Ctrl + Alt + E （在其他系统上，seems to be？{{1}并且是可配置的）

将命令扩展为所需的ctrl+x+*，然后按Enter键。不应该扩展的变量必须是单引号。

虽然没有像zsh那样的东西。
