dumpe2fs:tldr:cb35d
dumpe2fs: Print the detailed group information block numbers in hexadecimal format.
$ dumpe2fs -x ${-dev-sdXN}
try on your machine
The command dumpe2fs -x ${-dev-sdXN}
is used to get detailed information about the ext2, ext3, or ext4 filesystem on a specific block device, which is denoted as /dev/sdXN
.
Here's a breakdown of the command and its components:
dumpe2fs
: This is the main command that allows you to extract information about the ext2, ext3, and ext4 filesystems.-x
: This is an option or parameter provided to thedumpe2fs
command. It instructsdumpe2fs
to output detailed information about the filesystem.${-dev-sdXN}
: This is a placeholder for the specific block device you want to analyze. The format/dev/sdXN
is used to represent block devices in Linux, where:sd
: Represents a SCSI disk device.X
: Represents a lowercase letter (a-z) that identifies a specific disk. For example,sda
,sdb
, etc.N
: Represents a number (1-15) indicating a partition on the disk. For example,sda1
,sdb2
, etc.
So, you need to replace ${-dev-sdXN}
with the appropriate block device you want to analyze. For example, if you want to analyze the first partition of the second SCSI disk, you would replace ${-dev-sdXN}
with /dev/sdb1
.
