Linux如何自定义自己的命令呢？修改 系统中的 ~/.bashrc 文件即可
在这个文件最后面使用alias命令重定义命令。
例如：
# novel-git begin alias n.r=\'less -s ${novel_path}/reading/`ls novel/reading`\' alias n.g=\'${novel_path}/auto-git.sh\' alias n.n=\'vim ${novel_path}/note\' export novel_path=~/novel # nove-git end
修改完成之后要使用命令 source ~/.bashrc 刷新
这个脚本是我的一个小说阅读器，左边阅读，右上笔记，右下使用git保存笔记到github
我的novel目录：
操作思路：
对于长的脚本，我们可以写一些脚本，放到特定的一个文件夹下，在bashrc文件中执行这个脚本，
对于短的命令，我们直接重命名即可。
