Summary
Understanding how Linux designates and manages
its devices is crucial
for any Linux user and hacker. Hackers will need to know what devices
are attached to a system and how much space is available. Because storage
devices often develop errors, we can check and
repair those errors with
fsck
. The
dd
command is capable of making a physical copy of a device,
including any deleted files.
