			The directory stack is a list of recently-visited directories. The <code>pushd</code> builtin adds directories to the stack as it changes the current directory, and the <code>popd</code> builtin removes specified directories from the stack and changes the current directory to the directory removed. The <code>dirs</code> 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 <code>DIRSTACK</code> shell variable.

pushd navigate/ #cd to navigate/ dir and adds absolute path to navigate/ dir to directory stack
dirs -v #manages dir stack, -v lists the stack verbosely
popd #consumes first pushed/added directory from stack
</source>

Demonstrate
<source lang="bash">
mkdir -p ./navigate/dir{1..3}
piotr@ubuntu /tmp $ pushd navigate/ #cd and added to left/top of the stack
/tmp/navigate /tmp
piotr@ubuntu /tmp/navigate $ pushd dir1/ #cd and added to left/top of the stack
/tmp/navigate/dir1 /tmp/navigate /tmp
piotr@ubuntu /tmp/navigate/dir1 $ pushd ../dir2/ #cd and added to left/top of the stack
/tmp/navigate/dir2 /tmp/navigate/dir1 /tmp/navigate /tmp
piotr@ubuntu /tmp/navigate/dir2 $ pushd ../dir3/ #cd and added to left/top of the stack
/tmp/navigate/dir3 /tmp/navigate/dir2 /tmp/navigate/dir1 /tmp/navigate /tmp
piotr@ubuntu /tmp/navigate/dir3 $ dirs -v #show the directory stack
0 /tmp/navigate/dir3

3 /tmp/navigate
4 /tmp

Additional options and switches
<source lang="bash">
dirs -c #clears out the directory stack
cd ~2 #cd taking advantage using directory stack, here cd to index.2 dir in the stack
#just remember index.0 always changes, to preserve the order always pushd dummy dir /or current dir .
