== 实现 ==
[[Multics]]有一个 <code>pwd</code> 命令（是 <code>print_wdir</code> 命令的短名称）<ref>{{cite web|title=working_dir, wd, print_wdir, pwd (Multics help segment)|url=http://web.mit.edu/multics-history/source/Multics/doc/info_segments/working_dir.info|access-date=7 March 2020|website=MIT|archive-date=2021-04-02|archive-url=https://web.archive.org/web/20210402141027/http://web.mit.edu/multics-history/source/Multics/doc/info_segments/working_dir.info}}</ref>，Unix的pwd命令由此起源。<ref>{{cite web|title=Unix and Multics|url=https://multicians.org/unix.html|access-date=7 March 2020|website=Multicians.org|last1=Van Vleck|first1=Tom|archive-date=2022-04-26|archive-url=https://web.archive.org/web/20220426051042/https://multicians.org/unix.html}}</ref>在大部分[[Unix shell]]，如[[Bourne shell]]、[[Almquist shell|ash]]、[[Bash (Unix shell)|bash]]、[[Korn shell|ksh]]和[[Z shell|zsh]]中，它是[[殼層內建指令|内建命令]] ，可以用[[POSIX]] [[C语言|C]]函数 <code>getcwd()</code> 或 <code>getwd()</code> 轻易实现。

它还在[[SpartaDOS X]]<ref>{{Cite web|title=SpartaDOS X 4.48 User Guide|url=http://sdx.atari8.info/sdx_files/4.48/SDX448_User_Guide.pdf|access-date=2021-10-10|archive-date=2021-10-10|archive-url=https://web.archive.org/web/20211010113045/http://sdx.atari8.info/sdx_files/4.48/SDX448_User_Guide.pdf}}</ref>、[[Panos (operating system)|PANOS]]<ref>{{Cite web|title=Chris's Acorns: Panos|url=http://chrisacorns.computinghistory.org.uk/Panos.html#CL|website=chrisacorns.computinghistory.org.uk|access-date=2021-10-10|archive-date=2016-03-31|archive-url=https://web.archive.org/web/20160331135522/http://chrisacorns.computinghistory.org.uk/Panos.html#CL}}</ref>和[[KolibriOS]]<ref>{{Cite web|title=Shell - KolibriOS wiki|url=http://wiki.kolibrios.org/wiki/Shell|website=wiki.kolibrios.org|access-date=2021-10-10|archive-date=2019-02-11|archive-url=https://web.archive.org/web/20190211231827/http://wiki.kolibrios.org/wiki/Shell}}</ref>上可用。[[DOS]]（<code>[[COMMAND.COM]]</code>）和[[Microsoft Windows]]（<code>[[cmd.exe]]</code>）中与之等价的是没有参数的<code>[[cd (命令)|cd]]</code>命令。[[Windows PowerShell]]还提供对等的<code>Get-Location</code> [[PowerShell|cmdlet]]，以及标准的别称<code>gl</code>与<code>pwd</code>。在 [[Windows CE 5.0]]上，<code>cmd.exe</code> ''（Command Processor Shell）''包含了<code>pwd</code>命令。<ref>{{Cite web|title=Command Processor Commands (Windows CE 5.0)|url=https://docs.microsoft.com/en-us/previous-versions/windows/embedded/ms907227(v=msdn.10)|website=docs.microsoft.com|access-date=2021-10-10|archive-date=2020-05-15|archive-url=https://web.archive.org/web/20200515171231/https://docs.microsoft.com/en-us/previous-versions/windows/embedded/ms907227(v=msdn.10)}}</ref>

自1987年的第二版起，Unix上的{{code|pwd}}就是[[X/Open]]可移植手册的一部分。它已被继承到POSIX.1第一版和[[單一UNIX規範|单一UNIX规范]]中。<ref>{{man|cu|wc|SUS}}</ref>它还在Unix第五版中出现过。<ref>{{man|1|pwd|FreeBSD}}</ref>GNU核心工具组打包的<code>pwd</code>版本由Jim Meyering编写。<ref>{{man|1|pwd|Linux}}</ref>

[[Windows PowerShell]]提供等价的“<tt>Get-Location</tt>”cmdlet并有标准别名“<tt>gl</tt>”和“<tt>pwd</tt>”。

数值分析环境[[MATLAB]]与[[GNU Octave]]包含一个 <code>pwd</code> 函数，行使类似的功能。<ref>{{Cite web|title=Identify current folder - MATLAB pwd|url=https://www.mathworks.com/help/matlab/ref/pwd.html|website=www.mathworks.com|access-date=2021-10-02|archive-date=2022-04-09|archive-url=https://web.archive.org/web/20220409080107/https://www.mathworks.com/help/matlab/ref/pwd.html}}</ref><ref>{{Cite web|title=Function Reference: pwd|url=https://octave.sourceforge.io/octave/function/pwd.html|website=octave.sourceforge.io|access-date=2021-10-02|archive-date=2022-04-20|archive-url=https://web.archive.org/web/20220420030327/https://octave.sourceforge.io/octave/function/pwd.html}}</ref>[[OpenVMS]]中则与<code>show default</code>等价。

== *nix上的示例 ==
{| class="wikitable"
!<code>Command</code>
!解释
|-
|<code>pwd</code>
|显示当前工作目录。例如：/home/foobar
|-
|<code>pwd -P</code>
|显示当前工作目录的物理路径，若有任何符号链接名称则不显示。例如：在目录/home/symlinked下有一个指向/home/realdir的符号链接，则显示/home/realdir
|-
|<code>pwd -L</code>
|显示当前工作目录的物理路径，且显示任何符号链接名称。例如：在目录/home/symlinked下有一个指向/home/realdir的符号链接，则显示/home/symlinked
|-
|}
注意：POSIX要求默认行为和提供 <code>-L</code> 开关时的行为相同。

== 工作目录环境变量 ==
在使用cd命令时，POSIX壳层会设置下列[[环境变量]]：<ref>{{Cite web|title=cd|url=https://pubs.opengroup.org/onlinepubs/9699919799/utilities/cd.html|website=pubs.opengroup.org|access-date=2021-10-02|archive-date=2021-11-09|archive-url=https://web.archive.org/web/20211109163602/https://pubs.opengroup.org/onlinepubs/9699919799/utilities/cd.html}}</ref>

; OLDPWD
: 上一个工作目录（由cd命令设置）。
; PWD
: 当前工作目录（由cd命令设置）。

* [[Pushd及popd|<tt>pushd及</tt><tt>popd</tt>]]
