pushd: Rotate stack by making the 5th element the top of the stack.
$ pushd +4
try on your machine
The command "pushd +4" is used to navigate forward through directory history.
When you navigate to different directories, the pushd command keeps track of the directory history. The "+" sign followed by a number represents the number of directories you want to navigate forward in the directory stack.
For example, if you have navigated through several directories and then execute "pushd +4", it will navigate you four directories forward in the history stack. This means it will change your current directory to the directory that was four positions ahead in the stack.
