What is block device in Linux?
Block devices are characterized by random access to data organized in fixed-size blocks. Examples of such devices are hard drives, CD-ROM drives, RAM disks, etc. … To simplify work with block devices, the Linux kernel provides an entire subsystem called the block I/O (or block layer) subsystem.
How can I get a list of all blocked devices?
The best way to list anything in Linux is to remember the following ls commands:
- ls: List files in the file system.
- lsblk: List block devices (for example, the drives).
- lspci: List PCI devices.
- lsusb: List USB devices.
- lsdev: List all devices.
