pushd命令用于更改新目录并（或）压栈，或者把栈里的某个目录推到栈顶。
语法格式: pushd [参数]
常用参数:
| +N | 把正数第N个放到栈顶 |
| -N | 把倒数第N个放到栈顶 |
| -n | 不切换，只压栈 |
| dir | 要推送的目录 |
参考实例
添加目录到堆栈，改变了当前工作目录:
[[email protected] ~]# dirs ~ [[email protected] ~]# pushd ~/Desktop ~/Desktop ~
添加目录到堆栈，当前工作目录不变:
[[email protected] ~]# dirs ~ [[email protected] ~]# pushd -n ~/Desktop ~ ~/Desktop [[email protected] ~]# pushd -n ~/Pictures ~ ~/Pictures ~/Desktop
调整顺序:
[[email protected] ~]# pushd +1 ~/Pictures ~/Desktop ~ [[email protected] ~]# pushd -1 ~/Desktop ~ ~/Pictures [[email protected] ~]# pushd ~ ~/Desktop ~/Pictures
