wipefs:tldr:d3291

The command you provided is:

sudo wipefs --all ${-dev-sdX}*

Here's the breakdown of the command:

• sudo: It is used to execute the subsequent command with administrative privileges. It allows the user to run commands as a superuser or another user.
• wipefs: It is a command-line utility that is used to erase filesystem signatures (filesystem metadata) from a device or a file.
• --all: It is an option for wipefs command to erase all filesystem signatures found on the given device(s).
• ${-dev-sdX}*: This part of the command is a placeholder for specifying the device(s) on which the wipefs operation should be performed. The ${-dev-sdX}* is probably a typo or an incomplete placeholder as it does not represent a valid device name. Typically, the sdX part of the device name refers to a specific storage device (e.g., /dev/sda, /dev/sdb, etc.), and the * represents wildcard character for possible additional device names.

So, to utilize this command effectively, you need to replace ${-dev-sdX}* with the actual device name(s) you want to wipe filesystem signatures from.
