dd is a command-line utility for Unix, Plan 9, Inferno, and Unix-like operating systems and beyond, the primary purpose of which is to convert and copy files. [1] On Unix, device drivers for hardware (such as hard disk drives) and special device files (such as /dev/zero and /dev/random) appear in the file system just like normal files; dd can also read and/or write from/to these files ...
XZ Utils can compress and decompress the xz and lzma file formats. Since the LZMA format has been considered legacy, [2] XZ Utils by default compresses to xz.. In most cases, xz achieves higher compression rates than alternatives like zip, [3] gzip and bzip2.
Many data eradication programs also provide multiple overwrites so that they support recognized government and industry standards, though a single-pass overwrite is widely considered to be sufficient for modern hard disk drives. Good software should provide verification of data removal, which is necessary for meeting certain standards.
ddrescue uses a sophisticated algorithm to copy data from disk drives, and other storage devices, causing as little additional damage, if they are failing, as possible. [2] It is considered to have the most sophisticated implementation of a block-size-changing algorithm in free and open source software , [ 3 ] [ 4 ] and is considered an ...
In computing, tar is a computer software utility for collecting many files into one archive file, often referred to as a tarball, for distribution or backup purposes. The name is derived from "tape archive", as it was originally developed to write data to sequential I/O devices with no file system of their own, such as devices that use magnetic tape.
The magic SysRq key is a key combination understood by the Linux kernel, which allows the user to perform various low-level commands regardless of the system's state. It is often used to recover from freezes , or to reboot a computer without corrupting the filesystem . [ 1 ]
The Linux distribution Dragora GNU/Linux-Libre employs lzip for its software packages. Lzip is used to distribute the Time Zone Database from IANA, [10] and the GNU version of the Linux kernel. [11] The European Parliament publishes complete dumps of its database in JSON format compressed with lzip. [12] Lzip is used in NASA's Planetary Data ...
