e2freefrag: Check how many free blocks are present as contiguous and aligned free space.
$ e2freefrag ${-dev-sdXN}
try on your machine
The command e2freefrag ${-dev-sdXN}
is not a valid command syntax.
However, assuming it was supposed to be a curly braces syntax like e2freefrag ${dev-sdXN}
, it is likely trying to use the value of the variable dev-sdXN
as an argument for the e2freefrag
command.
In this case, the value of dev-sdXN
should represent the device name or path of a disk partition, such as '/dev/sda1'. The e2freefrag
command is used to display the fragmentation information of an ext2/ext3/ext4 filesystem on the given device.
By substituting the variable value into the command, it would look like e2freefrag /dev/sdXN
. This command would analyze the fragmentation level of the specified filesystem on the given device.

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