• Create a new volume through a text user interface and use /dev/urandom as a source of random data:

veracrypt --text --create --random-source=/dev/urandom

• Decrypt a volume interactively through a text user interface and mount it to a directory:

veracrypt --text path/to/volume path/to/mount_point

• Decrypt a partition using a keyfile and mount it to a directory:

veracrypt --keyfiles=path/to/keyfile /dev/sdXN path/to/mount_point

• Dismount a volume on the directory it is mounted to:

veracrypt --dismount path/to/mounted_point
