Question

When I change into a directory with the cd command, I lose the previous working directory, unless I remember it in my memory. Is there some handy method to go back quickly?

Demo:

$ cd ~/some_path
$ cd /another_path
$ command_to_go_back_to_some_path

Answer 1

You can also do this

$ pushd ~/some_path
$ pushd /another_path
$ popd 
$ popd
