I wonder why nobody mentioned this.

There is a really useful use case for pushd and popd commands for working with several folders simultaneously.

You can navigate the stack very easily, since it is enumerated. Meaning, you can have several working folders at your disposal during work.

See a simple example below.

First, let's create example folder structure.

 user@vb:~$ mkdir navigate user@vb:~/navigate$ mkdir dir1 user@vb:~/navigate$ mkdir dir2 user@vb:~/navigate$ mkdir dir3 

Then you can add all your folders to the stack:

 user@vb:~/navigate$ pushd dir1/ ~/navigate/dir1 ~/navigate user@vb:~/navigate/dir1$ pushd ../dir2/ ~/navigate/dir2 ~/navigate/dir1 ~/navigate user@vb:~/navigate/dir2$ pushd ../dir3/ ~/navigate/dir3 ~/navigate/dir2 ~/navigate/dir1 ~/navigate 

You can look it up by:

 user@vb:~/navigate/dir3$ dirs -v 0 ~/navigate/dir3 1 ~/navigate/dir2 2 ~/navigate/dir1 3 ~/navigate 

To navigate safely, you need to add the last (zero) folder twice, since it will be always rewritten:

 user@vb:~/navigate/dir3$ pushd . user@vb:~/navigate/dir3$ dirs -v 0 ~/navigate/dir3 1 ~/navigate/dir3 2 ~/navigate/dir2 3 ~/navigate/dir1 4 ~/navigate 

Now, you can jump around through these folders and work with stack as with aliases for the folders. I guess the following part is self explanatory:

 user@vb:~/navigate/dir3$ cd ~4 user@vb:~/navigate$ dirs -v 0 ~/navigate 1 ~/navigate/dir3 2 ~/navigate/dir2 3 ~/navigate/dir1 4 ~/navigate user@vb:~/navigate$ cd ~3 user@vb:~/navigate/dir1$ dirs -v 0 ~/navigate/dir1 1 ~/navigate/dir3 2 ~/navigate/dir2 3 ~/navigate/dir1 4 ~/navigate user@vb:~/navigate/dir1$ touch text.txt user@vb:~/navigate/dir1$ cp text.txt ~2 user@vb:~/navigate/dir1$ ls ~2 text.txt user@vb:~/navigate/dir1$ dirs -v 0 ~/navigate/dir1 1 ~/navigate/dir3 2 ~/navigate/dir2 3 ~/navigate/dir1 4 ~/navigate

Additional tip is to create some alias for dirs -v.

For example:

# In ~/.bashrc alias dirs="dirs -v"
