e4defrag: Print errors and the fragmentation count before and after each file.
$ e4defrag -v ${-dev-sdXN}
try on your machine
The command e4defrag -v ${-dev-sdXN}
performs a defragmentation on a specific Ext4 filesystem partition on a Linux system. Here is the breakdown of the command:
e4defrag
: This is the command-line tool used for defragmenting Ext4 filesystems.-v
: It is an option that specifies the verbose mode. When enabled, it provides more detailed information about the defragmentation process while it is being executed.${-dev-sdXN}
: This is a placeholder for the specific partition to be defragmented. Replace${-dev-sdXN}
with the actual path of the Ext4 filesystem you want to defragment.
Here's what each part of ${-dev-sdXN}
represents:
${-}
: This is used to indicate that the following text is a variable or placeholder.dev
: It represents the device or disk where the partition is located. For example, if the partition is on/dev/sda1
, you would replace${dev}
withsda
.sdXN
: TheX
refers to the specific disk identifier (e.g., a, b, c, etc.), andN
represents the partition number. If the partition you want to defragment is, for instance,/dev/sda4
, you would replace${sdXN}
withsda4
.
So, to use this command, you would replace ${-dev-sdXN}
with the actual path of the Ext4 filesystem partition you want to defragment, such as /dev/sda4
.

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