If you are in a subdirectory such as
/PROJECTS/P1/A/A1/A11, what single command would you use to return to your home directory from the current working directory?
The easiest but not only way to return to user's home directory from any directory within a filesystem is to use cd command without any options and arguments.
$ cdit is also possible to use:
$ cd ~ OR $ cd $HOME OR $ cd ~/However, if your home directory was a last directory you have visited previously before you navigated to
/PROJECTS/P1/A/A1/A11you can also use:
$ cd -
