Linux command line : File System

Linux Filesystem Management

Aim : To study file system in Linux.

Theory : Linux supports a large number of file systems, from journaling to clustering to cryptographic. Linux is a wonderful platform for using standard and more exotic file systems and also for developing file systems. 

Following Commands are used in File system management

badblocks		Used to search a disk or partition for badblocks.
cfdisk		Similar to fdisk but with a nicer interface.
debugfs		Allows direct access to filesystems data structure.
df		Shows the disk free space on one or more filesystems.
dosfsck		Check and repair MS-Dos filesystems.
du		Shows how much disk space a directory and all its files contain.
dump		Used to back up an ext2 filesystem. Complement is restore.
dumpe2fs		Dump filesystem superblock and blocks group information. Ex: dumpe2fs /dev/hda2
e2fsck		Check a Linux second extended filesystem.
e2label		Change the label on an ext2 filesystem.
exportfs		Used to set up filesystems to export for nfs (network file sharing).
fdisk		Used to fix or create partitions on a hard drive.
fdformat		Formats a floppy disk.
fsck		Used to add new blocks to a filesystem. Must not be run on a mounted file system.
hdparm		Get/set hard disk geometry parameters, cylinders, heads, sectors.
mkfs		Initializes a Linux filesystem. This is a front end that runs a separate program depending on the filesystem's type.
mke2fs		Create a Linux second extended filesystem.
mkswap		Sets up a Linux swap area on a device or file.
mount		Used to mount a filesystem. Complement is umount.
rdev		Query/set image root device, swap device, RAM disk size of video mode. What this does is code the device containing the root filesystem into the kernel image specified.
rdump		Same as dump.
rmt		Remote magtape protocol module.
restore		Used to restore an ext2 filesystem.
setfdprm		Set floppy drive parameters.
swapoff(8)		Used to de-activate a swap partition.
swapon(8)		Used to activate a swap partition.
sync		Forces all unwritten blocks in the buffer cache to be written to disk.
tune2fs		Adjust tunable filesystem parameters on second extended filesystems.
umount		Unmounts a filesystem. Complement is mount.
