Bash功能->没有找到指令 [英] Bash Function -> Command not found

问题描述

你好急，我正在尝试学习Bash，但似乎无法使该基本脚本正常工作.

Hi gusy I am trying to learn Bash and cannot seem to get this basic script to work.

#!/bin/bash

function system_info
{    
    echo "function system_info"
}

$(system_info)

我得到一个功能:找不到命令.

I get a function: command not found issue.

非常感谢任何帮助

推荐答案

Bash试图评估system_info函数输出的字符串.您将尝试以下操作，只需运行以下功能即可:

Bash is trying to evaluate the string that is outputted by the system_info function. You'll want to try the following, which will just simply run the function:

system_info

或将输出值存储到变量:

or to store the outputted value to a variable:

value=$(system_info)
