How to Use Linux Commands pushd and popd
Navigating through directories in Linux can sometimes feel cumbersome, especially when you’re working on multiple projects or need to switch between various folders frequently. Fortunately, Linux provides a couple of handy commands—pushd and popd—that can make directory management more efficient. These commands allow you to change directories while keeping track of your previous locations, enabling you to return to them easily.
In this tutorial, we will explore how to use pushd and popd effectively. Whether you are a seasoned Linux user or just starting, mastering these commands can significantly enhance your workflow. We’ll break down the commands, give you practical examples, and show you how they can simplify your command-line navigation.
Use the pushd Command in Linux
There are two entries in the stack after the first pushd command: your left directory and the one you have.
The pushd command has the following:
$ pushd ~/Desktop
Output:
~/Desktop ~
The directory of the terminal will be changed to Desktop. i.e., ~/Desktop$
~/Desktop$ pushd ~/Music
Output:
~/Music ~/Desktop ~
Now, it’s changed to Music.
$ pushd ~
Output:
~ ~/Music ~/Desktop ~
We returned to our home directory with the last pushd command.
Therefore, the tilde~, which symbolizes our home directory, is the first and last entry on the stack. It indicates that despite a directory already present in the stack, we will add it again for other pushd commands.
Use the popd Command in Linux
The popd command is being used to remove directories from the stack. When we look at the directory stack, we see that /home/user is in position 1.
We type the following to pass the number to popd to remove it from the stack:
$ dirs -v -l
Output:
0 /home/user
1 /home/user/Music
2 /home/user/Desktop
3 /home/user
$ popd +1
Output:
~ ~/Desktop ~
The /home/user directory was eliminated, and all directories below it in the stack were pushed up one position.
$ popd
Output:
~/Desktop
We’ll use popd to remove the top-most directory from the stack and replace it with the second-most directory.
This is now the directory you recently moved out of, so you’ve been redirected back to it.
Overstamping the Stack
It’s simple to revert to old habits and shift directories with cd.
You’ll stamp over the first directory in the stack if you do so. It is unavoidable because the first slot is designated for the current working directory, and none move.
To do so, type the following into the terminal:
$ dirs -v -l
Output:
0 /home/user/Desktop
$ cd ~/Music
~/Music$ dirs -v -l
Output:
0 /home/user/Music
You’ll have a super-fast way to jump between folders once you get familiar with the pushd and popd commands and potentially utilize them to construct a few aliases.
Conclusion
In summary, the pushd and popd commands are invaluable tools for anyone who frequently navigates through directories in Linux. They not only allow you to change directories seamlessly but also help you manage your workflow more effectively, especially when working with multiple projects or repositories. By incorporating these commands into your daily routine, you can save time and enhance your productivity.
