#CYBER SHADOW PHYSICAL COPY INSTALL#
Install libncursesw5-dev, or your distribution's equivalent package.While some might not enjoy this game's old-school look and gameplay, or its toughness, fans of vintage arcade games will have fun on this nostalgia trip.Install Dub, if it wasn't included with your D compiler.Note that you will need a compiler supporting D v2.097 or newer - the compiler in your distribution's repositories might be too old. Clone this repository and build from source (see below).
#CYBER SHADOW PHYSICAL COPY DOWNLOAD#
Download a static binary from the releases page.Via package manager, if it is packaged by your distribution (see on the right).Logical and physical sampling modes can help understand RAID space usage, especially when using multiple profiles.ītdu can be installed in one of the following ways: The -expert mode enables the collection and display of additional size metrics, providing more insight into the allocation of objects with non-trivial sharing. This btrfs "dark matter" can be an easily overlooked space hog, which can be eliminated by rewriting or defragmenting affected files.ītdu shows explanations for hierarchy objects and common errors, which can help understand how btrfs uses disk space. data in extents containing older versions of file content which has since been overwritten. If you use btrfs data compression (whether to save space, improve performance, or conserve flash writes), btdu can be used to estimate how much real disk space compressed data uses.Ī feature unique to btdu is the ability to estimate the amount of space used by unreachable parts of extents, i.e. the amount of "new" data in that snapshot. YYYY-MM-DD-HH-MM-SS): the size of snapshots displayed in btdu will thus indicate data that occurs in that snapshot or any later one, i.e. An emergent effect of this property is that it can be used to estimate snapshot size, if your snapshots use a fixed-length lexicographically-ordered naming scheme (such as e.g. When an extent is in use by multiple files or snapshots, to decide where to place it in the browsable tree, btdu picks the path with the shortest length, or the lexicographically smaller path if the length is the same. This is useful if the disk is full, and some space must be freed urgently to restore normal operation. Because it queries raw filesystem metadata, btdu requires root privileges to run.ītdu needs to collect only 100 samples to achieve a ~1% resolution, which means it can identify space hogs very quickly.By nature of its algorithm, btdu works correctly with compression and other btrfs filesystem features.(The shortest path is used when placing the sample in the tree for visualization.) btdu counts extents used by multiple files only once.
There is no way to analyze only a particular subdirectory or subvolume. btdu analyzes entire filesystems only.Though wildly inaccurate at first, they become progressively more accurate the longer btdu is allowed to run. btdu starts showing results instantly.It differs from classic analyzers through the following properties: Though it works by taking random samples, it is "eventually" accurate.
It works according to the following algorithm: (btrfs compression in particular is challenging to classic analyzers, and special tools must be used to query compressed usage.)ītdu is a sampling disk usage profiler for btrfs.
