1. Take installing the wget tool as an example

First download a wget rpm package on the windows browser

4. Set environment variables

用户使用报告_linux使用root用户_用户使用报告模板

In the home directory, directly edit the .bashrc file and lower the path of the executable program to the system PATH

In this wayLinux uses the root user and can directly execute the wget command

<span class="token comment"># .bashrc</span>
<span class="token comment"># Source global definitions</span>
<span class="token keyword">if</span> <span class="token punctuation">[</span> -f /etc/bashrc <span class="token punctuation">]</span><span class="token punctuation">;</span> <span class="token keyword">then</span>
<span class="token keyword">.</span> /etc/bashrc
