如何为grep -R编写别名? [英] How do I write an alias for grep -R?

问题描述

我最终输入

grep -Rni pattern .

很多.如何将其设置为别名

and awful lot. How do I make this into an alias like

alias gr='grep -Rni $@ .'

运行可以提供:

$ gr pattern
grep: pattern: No such file or directory

即使别名看起来很好:

$ type gr
gr is aliased to `grep -R $@ .'

似乎$ @和.在实际执行时被交换.

It seems that the $@ and the . get swapped when it's actually executed.

推荐答案

创建一个函数而不是别名.将其保存在mylibrary.sh等文件中，每当您要使用该功能时，都将其作为源文件

make a function instead of alias. Save it in a file eg mylibrary.sh and whenever you want to use the function, source the file

例如mylibrary.sh

eg mylibrary.sh

myfunction(){
 grep -Rni ...
}

#!/bin/bash
source mylibrary.sh
myfunction
