fsck /dev/(device) or fsck (mountpoint) to check one disk

fsck -A to check all disks

The first file system Linux supported was the MINIX file system.

fsck (means "file system check").

There are many files and file types on the Linux system

ext3 is the default file system for Red Hat Enterprise Linux.

The NTFS file system is supported in Linux by both a kernel module and several userspace programs. It is not supported as a root file system and is not recommended for permanent file storage.

The pros and cons of the Linux file system include the quote saying "On a UNIX system, everything is a file, if something is not a file, it is a process". You can consider this either a pro or a con.

The Linux ext3 file system is the default system in many linux derivatives. It allows for journalling, which the ext2 system did not. It also allows in-situ upgrades without asking for a backup first.

In every File system on Linux, a Super Block contains information about the file system: like type, name, size, status, it is metadata(data about data) for a file system.

The Linux VFS (Virtual File System) may be thought of as a sort of interface between the Linux kernel and the mounted file systems. There can be many different file system types mounted simultaneously and VFS allows the Linux kernel to see and address them all in a similar way. This provides Linux with a great deal of flexibility. [JMH]

Depends on the file system.

You don't edit inodes manually. They are managed by the file system driver.

The Linux file system is referred to as hierarchical, because it arranges files in directories, which are themselves arranged in directories, thus forming a tree.

You can set up file sharing between windows 7 and Linux mint 16 by simply installing the Ext2 Installable File System on windows which allow windows to read and write into the Linux file system.

It is usually an abbreviation for File System.

Super block is supposed to be the first sector of any file system that can be mounted on Linux operating system. It is supposed to contain information about the entire file system in that partition. It has magic number to specify which file system is used in that partition and other parameters to help read/write to that file system.

This depends on the Unix/Linux system release; vendors may differ in how they log information. Typically, in a Linux distro you can find sshd authorization errors in auth.log. Other systems use syslog or syslog.log, depending on how they are configured. Check your system information to see what the exact log file is called in your environment.

Ext3 refers to the third extended file system that has a journaling capability. It is the default and widely used file system in Linux operating systems.

There is no "the startup file" in Linux; depending on the type of system, there may not be any files at all. The Linux boot process has a number of steps, many of which are optional or have alternative implementations.

Windows uses 4 file systems: FAT, NTFS, exFAT, and ReFS. "Linux" supports dozens of file systems, there are too many to mention. The differences between them are massive and specific to the file system in question. For a proper answer you need to read . It is incorrect to say "the Linux file system is faster than Windows" because it's dependent on the data, and of course because there is no "Linux file system." It's incorrect to say "The Linux filesystem is more/less secure than the Windows file system" for the same reason. Drive encryption is available in both Windows and Linux. To the average user, there is no functional difference.

That depends on the file system being used. Linux doesn't have just one file system. But various features you'll often find in a filesystem include inode tables, journals, redundant superblocks, extents, etc. The Linux kernel itself will physically arrance the files on the disk itself with guidance from filesystem drivers, but you'll notice that Linux never fragments significantly.

If you are talking about accessing the partition from Linux, the kernel file system driver does not allow writing to NTFS partitions. You can write to the partition in Linux if you install the NTFS-3G file system. This is the only form of "write-protection" that should be on your system.

A journaling file system is a file system that keeps track of the changes in a journal before committing them to the main file system.If system crashes or power fails, such file systems replay the journal to bring file system to a consistent state.

Linux systems have access to a wide range of filesystems, however most Linux distributions default to ext3 or ext4. In the future it is our hope that the "standard" Linux filesystem will be btrfs.Linux supports many different file systems, including ext, ext3, ext4, ReiserFS, Reiser4, JFS, btrfs, and XFS.
