Linux Command for Listing Disk Devices

What is the Linux command used to list the current disk devices connected to a computer?

1) ls -l
2) fdisk -l
3) show drives
4) geom

Answer:

The Linux command 'fdisk -l' is used to list the current disk devices connected to a computer.

Reflection:

The Linux command that can be used to list the current disk devices connected to the computer is 'fdisk -l'. This command must be run with superuser privileges and provides detailed partition tables for all connected devices. Other listed options such as ls -l, show drives, and geom are not appropriate for listing disk devices in Linux.

Explanation:

The command fdisk is a disk partition utility that provides disk partitioning functions. When used with the -l option, it lists the partition tables for the specified devices or all devices if none are specified. This command must typically be run with superuser privileges to ensure full access to all devices.

ls -l lists the files in the current directory in a long format, including file permissions and ownership information. show drives is not a standard Linux command, and geom relates to FreeBSD's geom framework, not a standard Linux command for listing disk devices.

To use fdisk -l, simply open the terminal and type sudo fdisk -l. Enter your password when prompted to get a list of all disk devices currently connected to your computer.
