∟File Systems

This chapter provides introductions and tutorial on Linux file systems. Topics include 'df' to see disk free spaces of mounted file systems; 'mount' to access 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', 'cifs-utils', 'nfs-utils' to support Windows NTFS/shared folders and Linux NFS.

"df" - Display Free Space of File System

Mount USB Drive as File System

"dd" - Copy Data from/to Storage Devices

Use "dd" Command to Test I/O Speed

"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

Reformat NTFS Partition into EXT4 Partition

NFS (Network File System)

Mount NFS (Network File System) on macOS

/etc/mtab and /etc/fstab Files

Unreachable Remote File Systems

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.
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.
"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.
NSF (Network File System) allows you to share sub-directories between Linux systems.
you must append "/" at the end of the NFS file system name when mounting it on macOS computers.
/etc/mtab holds currently mounted file systems.
/etc/fstab holds file systems to be mounted at boot time.
