Linux command line navigation tips: the basics of pushd and popd commands

In the first part of this series, we focused on the command line navigation aspect in Linux by discussing the usage of the cd – command. Some other related points/concepts were also discussed. Taking the discussion further, in this article, we will be discussing how you can have a faster navigation experience on the Linux command line using the pushd and popd commands.

Now, when you require a plate, you pick the one which is at the top of the pile, use it, and then pick the next one when required.

Similar is the concept of pushd and popd commands. There’s a directory stack on your Linux system where you can pile up directory paths for future use. You can quickly see the contents of the stack at any point in time using the dirs command.

Here’s an example that shows the output of the dirs command on my system immediately after the command line terminal was launched: $ dirs Continue reading
