∟File Systems

Provides introductions and tutorial on Linux file systems. Topics include 'df' to see disk free spaces of mounted file systems; 'mount' to connect to USB drive file systems; 'fdisk' to list partitions and file system types; 'dd' to copy data and test I/O speed; 'hdparm' to manage hard disk parameters; install 'ntfs-3g' and 'cifs-utils' to support Windows NTFS and shared folders.

"df" - Display Free Space of File System

Mount USB Drive as File System

"fdisk" - Format Disk Partitions

"dd" - Copy Data from/to Storage Devices

Use "dd" Command to Test I/O Speed

"hdparm" - Hard Disk Parameters

"du" - Display Disk Usage of Directories

Mount Windows NTFS File System

Access Persmissions on "ntfs-3g" File System

Mount Windows Shared Folders

W95 Ext'd (LBA) Partition

File System Types, IDs and Formats

LVM (Logical Volume Manager)

"parted" - Partition Manipulation Program

Reformat NTFS Partition into EXT4 Partition

Takeaways:

"df” command can be used to display free spaces of mounted file systems.
"mount" command can be used to bring file system partitions online. "umount" command can be used to bring them offline.
"fdisk -l " command can be used to list file system partitions and their format types of a given storage device.
"dd" command can be used to copy data as continuous blocks of bytes from one device to another bypassing file system structures.
"dd" command can also be used to test I/O (Input and Output) speed of a given storage device.
"hdparm" command can be used to to gather hard disk identification information and get/set its individual parameters.
Mounting Windows NTFS file systems requires installation of the ntfs-3g device driver.
Mounting Windows shared folders requires installation of the cifs-utils device driver.
LVM (Logical Volume Manager) allows you to create a single or multiple logical storage volumes across multiple physical disks or partitions.
"parted" is a better alternative tool than "fdisk" to manipulate hard disk partitions.
"fsmk -t ext4" command can be used to format a partition into an EXT4 file system.
