shell prompt(PS1)与Carriage Return(CR)关系（转自：shell十三问）

当你成功登陆一个shell终端的文件界面之后，大部分的情形下，你会在屏幕上看到一个不断闪烁的方块或者底线（视不同的版本而别），我们称之为游标(cursor).cursor作用就是告诉你接下来你从键盘输入的按键所插入的位置，且每输入一个键，cursor便向右移动一个格子，如果连续输入太多的话，则自动接在下一行输入。加入你刚完成登陆，还没有输入任何按键之前，你所看到的cursor所在的位置的同一行的左

一、何为shell（转自：shell十三问）

shell是什么东西之前，不放让我们重新审视使用者和计算机系统的关系。我们知道计算机的运作不能离开硬件，但使用者却无法直接操作硬件，硬件的驱动只能通过一种称为“操作系统(OS)"的软件来管控。事实上，我们每天所谈的"linux"，严格来说是一个操作系统，我们称之为"内核(kernel)".然而，从使用者的角度来看，使用者没办法直接操作一个kernel，而是通过kernel的"外壳"程序，也就是所谓
