blkdiscard: Discard the first 100 MB of a device.
$ blkdiscard --length ${100MB} /dev/${device}
try on your machine

The command "blkdiscard --length ${100MB} /dev/${device}" is used to discard the specified amount of data from a block device in Linux.

Here's a breakdown of the command:

  • "blkdiscard" is a utility command in Linux used to discard (or trim) blocks of data on a specified block device.

  • "--length ${100MB}" is an option in blkdiscard used to specify the length or size of data to be discarded. In this case, "${100MB}" is a placeholder that would be replaced with the actual value representing 100 megabytes (MB) of data.

  • "/dev/${device}" is the device path for the block device from which you want to discard the data. "${device}" is another placeholder that should be replaced with the actual name or identifier of the device.

So essentially, this command would discard a specified amount of data from the block device identified by "/dev/${device}". Make sure to replace "${100MB}" and "${device}" with their appropriate values for the command to work correctly.
