wipefs:tldr:92578

The command you provided is used to wipe all file system signatures on a specific storage device. Here is a breakdown of each component:

• sudo: It is used to execute the command with administrative ("superuser") privileges. This allows the command to make changes to the system, including wiping file system signatures.

• wipefs: It is a command-line utility in Linux used to erase or delete file system signatures from storage devices. File system signatures are a set of bytes that indicate the presence of a specific file system on a device.

• --all: This option specifies that all available file system signatures on the device should be wiped. It ensures that any existing file system signatures are completely removed.

• --force: This option instructs the command to force the operation without prompting for confirmation. It avoids any prompts or warnings, allowing the command to execute without user intervention.

• ${-dev-sdX}: This is a placeholder for a specific storage device. The format /dev/sdX is commonly used to represent storage devices in Linux, where X is replaced by a specific device identifier (e.g., /dev/sda, /dev/sdb, etc.). By specifying the target device, the command will wipe file system signatures on that specific device.

Overall, the sudo wipefs --all --force /dev/sdX command will wipe all file system signatures on the specified device (represented as /dev/sdX) without any confirmation prompts.
