Fedora bash程序无法正常运行 [英] Fedora bash program not working properly

问题描述

我试图只运行一个简单的bash命令，但是我不确定我错过了什么

I am trying to just run a simple bash command but i'm not sure what i'm misssing

#!/bin/bash
$person = Craig Baiey
echo $person
echo '$person'
echo "$person"

每次我运行它都会收到错误消息 第2行:=:找不到命令

everytime I run it i get an error line 2: =: command not found

$ person

推荐答案

空格是=周围的问题.应该是:

Space is the problem around =. It should be:

person="Craig Baiey"

• 您没有将变量分配给名称为$的变量.
• 那里也需要引号.
• You don't assign into variable with $ in name.
• And quotes are also required there.

此行将不会显示变量的值:

btw this line won't print the variable's value:

echo '$person'

由于shell由于单引号的存在而无法扩展.它将改为文字$person

As shell won't expand it due to presence of single quotes. It will instead literal $person
