The Directory Stack (Bash Reference Manual)
6.8 The Directory Stack
|• Directory Stack Builtins||Bash builtin commands to manipulate the directory stack.|
The directory stack is a list of recently-visited directories. The
pushd builtin adds directories to the stack as it changes the current directory, and the
popd builtin removes specified directories from the stack and changes the current directory to the directory removed. The
dirs builtin displays the contents of the directory stack. The current directory is always the "top" of the directory stack.
The contents of the directory stack are also visible as the value of the
DIRSTACK shell variable.
