‘Bring the revelations from the edge of a shell .’ 🦪🦉

The three real wepons on SHell : ^{来自“过去物质”的三项启示：}

• exec : the old's end, the new's begin. ^{终结的调用 —— 清理残余的旧物并迎接新生。}
• eval : it will write itself by itself ... ^{编程的编程 —— 生命一旦诞生就会自己找到出路。}
• echo : looking to the self ^{传递的回声 —— 审视的可能是反馈的基础。}
