Directory stack
Up one level
-
The directory stack is a list of recently-visited directories. The pushd built-in adds directories to the stack as it changes the current directory, and the popd built-in removes specified directories from the stack and changes the current directory to the directory removed.
Content can be displayed issuing the dirs command or by checking the content of the DIRSTACK variable.
More information about the workings of this mechanism can be found in the Bash info pages.
