udisksctl:tldr:98d50
The command "udisksctl info --block-device ${-dev-sdX}" is used to gather information about a specific block device in Linux using the udisksctl utility.
Let's break down the command:
-
"udisksctl" is the command itself, used to interact with the udisks daemon and perform various disk management tasks.
-
"info" is the action or subcommand used to retrieve information about a specific device.
-
"--block-device" is an option that specifies that we want to get information about a block device.
-
"${-dev-sdX}" is a placeholder representing the actual device name. In this case, "sdX" is used as a generic term to refer to a specific disk device. The actual device name should be specified here, e.g., "sda" for the first SATA disk.
By executing this command with the correct device name, you will get detailed information about the specified block device. This can include details such as the device's size, partition information, filesystem type, mount status, and more.
