fuse captive	<reply> FUSE (Filesystem in Userspace) is a !kernel driver that allows non-root users to create their own filesystems. See http://en.wikipedia.org/wiki/Filesystem_in_Userspace for more on FUSE. Some examples of filesystems that use FUSE are !ntfs-3g, sshfs and isofs. A full list of Filesystems that use FUSE is here: http://fuse.sourceforge.net/wiki/index.php/FileSystems	Added by apokryphos Date: 2006-06-19 11:48:16 Last edited by Amaranth Date: 2007-08-07 14:36:30 Requested 1130 times
fsck	the FileSystem ChecKer, which runs automatically when you boot if you didn't shutdown cleanly. Type "man fsck" for information on running it manually. The command "sudo touch /forcefsck && sudo shutdown -r now" will force a reboot and a filesystem check; "sudo touch /fastboot" will skip a filesystem check at next reboot	Added by LjL Date: 2006-12-13 20:01:03 Last edited by tsimpson Date: 2011-05-04 07:55:19 Requested 1048 times
ext3	the default filesystem on older versions of Ubuntu, and the most popular on Linux. You can read/write from Windows to ext3 via http://www.fs-driver.org	Added by apokryphos Date: 2006-06-18 21:35:14 Last edited by rww Date: 2011-01-02 04:11:40 Requested 623 times
defrag defragmentation defragment	<reply> The default Ubuntu filesystem (ext4) is engineered to avoid fragmentation issues in most cases. However, there is an online defragmentation tool available if needed. For more information, see `man e4defrag`	Added by Seveas Date: 2006-07-20 22:49:03 Last edited by dax Date: 2016-03-30 19:26:16 Requested 368 times
plymouth	<reply> Plymouth is an application that runs very early in the boot process (even before the root filesystem is mounted!) that provides a graphical boot animation while the boot process happens in the background. To change your Plymouth theme use « sudo update-alternatives --config default.plymouth && sudo update-initramfs -u »	Added by Pici Date: 2010-12-02 14:07:39 Last edited by Jordan_U Date: 2013-04-29 00:05:35 Requested 161 times
btrfs	<reply> Btrfs is a filesystem available for Ubuntu. It is not recommended by default, and should not be used for important data. See https://help.ubuntu.com/community/btrfs	Added by LjL Date: 2011-11-06 15:30:17 Last edited by dax Date: 2016-04-08 06:46:24 Requested 132 times
sshfs	a !Fuse based filesystem which allows you to mount a remote system over !SSH - See https://help.ubuntu.com/community/SSHFS for instructions	Added by jpds Date: 2009-02-15 18:29:16 Last edited by tsimpson Date: 2011-03-03 21:45:11 Requested 100 times
xfs	a high-performance journaling filesystem originally developped by Silicon Graphics for their IRIX OS. It is now fully supported by Linux so you can install Ubuntu on it if you wish. More info at http://en.wikipedia.org/wiki/XFS	Added by Seveas Date: 2007-04-27 00:35:39 Requested 74 times
addingfs	<reply>If you are adding space to your Ubuntu installation mounting a newly created unix filesystem (ext3, xfs, jfs, etc) you can not set permissions (read, write, etc) filesystem-wide like you do when mounting filesystems that do not support unix permissions (vfat, ntfs, hfs, etc). See !permissions and !fstab	Added by jrib Date: 2008-02-12 15:52:30 Last edited by jrib Date: 2008-02-12 15:58:35 Requested 50 times
lost+found lost	where !fsck places any files it gleans from a corrupt filesystem. These are files which had become unlinked from their parent directories.	Added by apokryphos Date: 2006-06-19 13:12:22 Requested 48 times
rm	<reply> The Unix 'rm' command removes files and directories from the filesystem. It is an extremly powerful tool, and you should not run 'rm' commands unless you fully understand them. Do not run arbitrary 'rm' commands you see online. For a beginning guide on using terminal commands, see https://help.ubuntu.com/community/UsingTheTerminal	Added by Seveas Date: 2006-06-18 19:07:55 Last edited by k1l_ Date: 2016-02-22 21:54:28 Requested 41 times
pkexec	<reply> pkexec is a PolicyKit tool that allows an authorized user to run (graphical) applications as another user. To run a graphical application (e.g. gedit) which can write to the entire filesystem, use e.g. "pkexec env DISPLAY=$DISPLAY XAUTHORITY=$XAUTHORITY gedit /etc/environment"	Added by knome Date: 2015-06-25 22:56:08 Last edited by hggdh Date: 2019-03-31 04:02:52 Requested 31 times
filesystems	<reply> ext3 and ext4 are the default filesystems in Ubuntu (and many other Linuxes). Alternative Linux filesystems include reiserfs and xfs. fat32 and ntfs are DOS/Windows filesystems. hfs and hfs+ are filesystems for the Mac.
