可以執行下面指令，安裝「manpages-posix」這個套件。

$ sudo apt-get install manpages-posix

然後就可以執行下面指令，觀看相關的說明

$ man cd

可以找到下面這一段說明

...略...

OPERANDS
       The following operands shall be supported:

       directory An absolute or relative pathname of the directory that shall become the new working directory. The interpretation  of  a  relative
                 pathname by cd depends on the −L option and the CDPATH and PWD environment variables. If directory is an empty string, the results
                 are unspecified.

       −         When a <hyphen> is used as the operand, this shall be equivalent to the command:

                     cd "$OLDPWD" && pwd

                 which changes to the previous working directory and then writes its name.

最近寫「Shell Script」剛好有用到這個功能，
雖然以前知道這個功能，但沒去查過「manpage」，
最近有查過上面這一段說明，所以還有印象。

謝謝分享

也可以嘗試看看 pushd, popd, dirs
