Modern Linux distributions include a /sys directory as a virtual filesystem (sysfs, comparable to /proc, which is a procfs), which stores and allows modification of the devices connected to the system, [20] whereas many traditional Unix-like operating systems use /sys as a symbolic link to the kernel source tree.
In computing, a directory structure is the way an operating system arranges files that are accessible to the user. Files are typically displayed in a hierarchical tree structure . File names and extensions
On Linux and modern BSD derivatives, this directory has subdirectories such as man for manpages, that used to appear directly under /usr in older versions. /var: Stands for variable. A place for files that might change frequently - especially in size, for example e-mail sent to users on the system, or process-ID lock files. /var/log
While storage devices usually have their size expressed in powers of 10 (for instance a 1 TB Solid State Drive will contain at least 1,000,000,000,000 (10 12, 1000 4) bytes), filesystem limits are invariably powers of 2, so usually expressed with IEC prefixes.
Filelight is a graphical disk usage analyzer part of the KDE Gear.. Instead of showing a tree view of the files within a partition or directory, or even a columns-represent-directories view like xdiskusage, it shows a series of concentric pie charts representing the various directories within the requested partition or directory and the amount of space they use. [1]
It is a clone of SGI's fsn file manager for IRIX systems, aimed to run on modern Linux and other Unix-like operating systems. [1] It is capable of representing file systems in two ways: MapV mode: files and directories are represented as cuboids of equal height, with the size of the cuboid representing the size of the file or directory.
By default, the Single UNIX Specification (SUS) specifies that du is to display the file space allocated to each file and directory contained in the current directory. Links will be displayed as the size of the link file, not what is being linked to; the size of the content of directories is displayed, as expected.
The maximum file, directory, and filesystem size limits grow at least proportionately with the filesystem block size up to the maximum 64 KiB block size available on ARM and PowerPC/Power ISA CPUs. Extents Extents replace the traditional block mapping scheme used by ext2 and ext3. An extent is a range of contiguous physical blocks, improving ...
