What is the use of Pushd and Popd?
The pushd command is used to save the current directory into a stack and move to a new directory. Furthermore, popd can be used to return back to the previous directory that is on top of the stack. It is very useful when we have to switch between two directories frequently.
What is pushd in shell?
pushd is a shell built-in command which allows us to easily manipulate the directory stack. This appends a directory to the top of the directory stack, or rotates the stack, making the new top of the stack the present working directory.
What is popd command?
The popd command changes the current directory to the directory that was most recently stored by the pushd command. Every time you use the pushd command, a single directory is stored for your use. However, you can store multiple directories by using the pushd command multiple times.
What do pushd and popd mean in Linux?
The pushd and popd commands allow you to work with directory stacks in Linux and Unix-like operating systems. They are used to add and remove directories from your directory stack. The “ d ” in pushd and popd stands for the directory. The concept of stacks is straightforward.
What does the D stand for in pushd and popd?

As we’re referring to a directory stack, it probably comes as no surprise that the “d” in pushd and popd stands for “directory.” These commands allow you to push directories onto, or pop them off of, the directory stack.
Where is the directory stack in pushd and popd?
The directory stack is a list of directories you have previously navigated to. The contents of the directory stack can be seen using the dirs command. Directories are added to the stack when changing to a directory using the pushd command and removed with the popd command. The current working directory is always on the top of the directory stack.
What does popd do when there is no argument?
When used with no argument, popd removes the top directory from the stack and navigates to the new top directory. Let’s say we have the following directory stack: If you run the popd command it will remove the /opt from the stack and change to the /usr/local directory:
