sudo fdisk -l
or to list only partitions of one particular disk
sudo fdisk -l /dev/sdb
Like ext4, to an existing directory :
sudo mount /dev/sdb3 iss_share
sudo cryptsetup isLuks -v /dev/sdb2
sudo cryptsetup open /dev/sdb2 iss_cyph_bridge
sudo cryptsetup status iss_cyph_bridge
Mount the partiton binded in /dev/mapper as a regular partition.
sudo mount /dev/mapper/iss_cyph_bridge iss_cyph
sudo umount /media/jovian/iss_share
sudo umount iss_cyph
sudo cryptsetup close iss_cyph_bridge
Useful for safe removal.
sudo udisksctl power-off -b /dev/sdb
