pushd

指令名称:

pushd

使用权限:

所有使用者

使用方式:

pushd [-n] [directory]

pushd [-n] [+N][-N]

说    明:

第一条语法:将directory压入目录堆栈;如果不带参数,则交换栈顶的两个目录项

第二条语法:循环移动目录堆栈,将第n项移到栈顶

参    数:

+N 循环移动堆栈,把从栈顶算起的第n项移到栈顶(栈顶项的索引号为0)

-N 循环移动堆栈,把从栈底算起的第n项移到栈顶(栈底项的索引号为0)

-n 不让新压入的目录成为当前目录

范    例:

参见5.5.4范例

### Windows Command Line `pushd` Usage The `pushd` command is used to save the current directory before changing to a new one. This allows users to easily navigate back using the complementary `popd` command. The syntax for this operation can be summarized as follows: #### Basic Syntax ```plaintext PUSHD path ``` Where `path` specifies either an absolute or relative location that becomes the active working directory after execution. When specifying network paths with `pushd`, it automatically creates temporary drive letters starting from Z: and moving backward through unused letters until reaching A:[^1]. For instance, executing commands like these would demonstrate typical usages: ```batch C:\> pushd C:\Program Files\MyApp\ C:\Program Files\MyApp> ``` This changes the present working directory while preserving the previous state on what's known internally within Windows as "the stack." Another example involving remote shares might look something along those lines below: ```batch C:\Users\User> pushd \\server\share Z:\> ``` Here, assuming no other drives are mapped at Z:, the system assigns this letter temporarily so long as the session persists or another mapping does not override it first[^2]. --related questions-- 1. What alternatives exist for managing directories without relying upon `pushd`? 2. How do environment variables interact when switching between folders via `pushd`? 3. Can multiple levels of directories be pushed onto the stack simultaneously? If yes, how? 4. Is there any performance impact associated with frequent use of `pushd` especially concerning network locations? 5. Are there equivalent functions available in PowerShell compared to traditional CMD utilities such as `pushd`?
