lsblk

lsblk is used to display details about block devices and these block devices(Except ram disk) are basically those files that represent devices connected to the pc. It queries /sys virtual file system and udev db to obtain information that it displays. And it basically displays output in a tree-like structure. This command comes pre-installed with the util-Linux package.

That is the reason you are unable to saw the directories /opt, /var and /tmp

/opt is for “the installation of add-on application software packages”.

/var is a standard subdirectory of the root directory in Linux and other Unix-like operating systems that contains files to which the system writes data during the course of its operation.

/tmp directory is a temporary landing place for files.
