What is pushd and popd in bash?
Both pushd and popd are shell builtin commands. 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.
What is the purpose of pushd and popd?
Overview. The pushd command saves the current working directory in memory so it can be returned to at any time, pushd moves to the parent directory. The popd command returns to the path at the top of the directory stack.
How does Pushd and Popd work?
pushd and popd work according to the “LIFO” (last in, first out) principle. In this principle, only two operations are allowed: push an item into the stack, and pop an item out of the stack. pushd adds a directory to the top of the stack and popd removes a directory from the top of the stack.
What does popd command do?
The popd command changes the current directory to the directory that was most recently stored by the pushd command. If you use the popd command, the directory on the top of the stack is removed and the current directory is changed to that directory.
What is pushd in Shell?

When used like this, popd does not change your working directory. It only manipulates your stack. The default behavior of popd, given no arguments, is to remove the first (zeroeth) item from your stack and make the next item your current working directory.
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.
