mkswap: Check a partition for bad blocks before creating the swap area.
$ sudo mkswap -c ${-dev-sdb7}
try on your machine
The command sudo mkswap -c ${-dev-sdb7}
in Linux is used to create a swap space on the specified device /dev/sdb7
while performing a full check for bad blocks on that device.
Here is a breakdown of the command:
sudo
: It is used to execute the command with administrative or superuser privileges.mkswap
: It is a command-line utility in Linux used to create a swap area or swap partition. Swap space is used by the operating system when there is a need for more memory than physically available.-c
: This option is used to instructmkswap
to perform a full check for bad blocks on the specified device. It will scan the device for bad blocks and mark them as unusable for swap space. This helps avoid using faulty or unreliable blocks for swapping.${-dev-sdb7}
: It seems there might be an error in this part of the command. A variable or device name is expected, but it is incorrectly formatted. A correct usage would be/dev/sdb7
, without the$
and{}
symbols.
Therefore, the corrected command would be: sudo mkswap -c /dev/sdb7
, which creates a swap area on the device /dev/sdb7
and performs a full check for bad blocks on that device.

never run a command you are not sure if it is safe.
