如何将命令提示符输出存储到perl中的veri中 [英] How to store command prompt output into the veriable in perl

问题描述

朋友，

我正在尝试将命令提示符输出存储到veriable中.
我在命令提示符下运行一些命令，该命令以单个值以及多个值给出输出.我想将这些值存储到数组变量中.但是我不知道如何获取命令提示符输出.

有人知道怎么做吗?
我正在谷歌上搜索，但没有得到任何有用的解决方案.

简单的方法是使用反引号:

list =`ls -al`;

-这将在一个变量中为您提供命令输出.如果希望将其拆分为行数组:

  @ list  = 拆分 

Hi Friends,

I am trying to store the command prompt output in to the veriable.
I am running some commands on command prompt which gives output in single value as well as in multiple values. I want to store those values into the array variable. But I dont know how to fetch the command prompt output.

Could anybody have an idea how to do it?
I am googling on it but didnt get any usefull solution yet.

Google[^] for more.

The simple way is to use backticks:

list = `ls -al`;

- that will give you the command output in one variable. If you want it split into an array of lines:

@list = split
